Bangladesh J. Plant Taxon. 27(1): 37‒65, 2020 (June) © 2020 Bangladesh Association of Plant Taxonomists PRELIMINARY TAXONOMIC STUDY ON HOMESTEAD FLORA OF FOUR DISTRICTS OF BANGLADESH: MAGNOLIOPSIDA GOUTAM KUMER ROY* AND SALEH AHAMMAD KHAN Department of Botany, Jahangirnagar University, Savar, Dhaka-1342, Bangladesh Keywords: Homestead flora; Magnoliopsida; Threatened Species; Four Districts; Bangladesh. Abstract This study has documented the contemporary taxonomic information on the species of the class Magnoliopsida (Dicotyledons) extant in the homestead areas of Dhaka, Gazipur, Manikganj and Tangail districts of Bangladesh. In these areas, the Dicotyledons are comprised of total 455 species under 302 genera belonging to 78 families. Fabaceae with 41 species is the largest family and Solanum and Lindernia are the largest genera. Total 238 species are herbs followed by 129 species of trees and 88 species of shrubs. Total 332 species are economically useful. The composition and distribution of the species of this plant group are remarkably variable in the homestead areas of the four districts. The current status of seven threatened species viz., Abroma augusta, Andrographis paniculata, Aniseia martinicensis, Mucuna bracteata, Pterocarpus santalinus, Rauvolfia serpentina and Tournefortia roxburghii, included in the Red Data Book of Bangladesh and extant in the study area, has been evaluated and described. This study has identified some threats to the homestead flora and formulated some recommendations for the conservation of threatened and declining native plant species of the study area. The data provided by this study will serve as an important baseline to track the trend of changes in the floristic composition and diversity and sustainable development of plant genetic resources in the homesteads of the study area. Introduction Dicotyledons are the most successful and dominant plant group (Heywood, 1993). They comprise about 62.5% of the total angiosperm species (ca. 400000) recorded from this planet so far (Leitch and Leitch, 2008). Dicots are the major biotic component of almost all ecosystems and essential for human being as the source of food, cloths, shelter, medicines, fodder and many other substances used in different puroses worldwide. Bangladesh is endowed with about 5,000 species of flowering plants, of which more than two third are Dicotyledonous (Khan, 1972-1987). Dicot plants dominate the forests, village groves and woodlands of Bangladesh (Khan and Afza, 1968; Khan and Banu, 1969; Khan, 1972-1987). Homesteads are privately owned dwellings in the rural and semi-urban settings that typically consist of a living area, kitchen, backyard, front yard, and sometimes a pond and patio (Muhammed et al., 2011). A homestead forest, or “homegarden”, is usually a complex mixture of deliberately planted vegetation and designed to produce natural products for the household uses or market sale. It is an operational unit, in which a number of crops are grown with livestock, poultry and fish production mainly for the purpose of the farmer’s basic needs (Leuschner and Khaleque, 1987). Bangladesh has 15.4 million homesteads occupying 0.3 million hectares of land that are providing major requirement of food, fruit, vegetables, timber and fuel wood (Abedin and Quddus, 1990). Plants of the homesteads are receiving increasing attention from scientists, practitioners and policymakers because of their social, economic, ecological and environmental benefits (Alam, 2011). *Author for correspondence, email: roy_kbd@yahoo.com mailto:roy_kbd@yahoo.com 38 ROY AND KHAN In Bangladesh, there is no specific management plan for the homestead forests (FAO, 2010) and the household owners are traditionally managing these. It is estimated that about 70% of timber, 90% of firewood, 48% of sawn and veneer logs, and almost 90% of bamboo requirements are met from homestead forests (Uddin et, al., 2002). During the last 40–50 years, the relative importance has shifted from the traditional forestry to homestead plantation (Roy et al., 2013). Previousely some detail floristic studies (Hooker, 1872-1897; Prain, 1903; Khan, 1972-1987; Ahmed et al., 2008-2009) were carried on covering the political boundary of Bangladesh. Many taxonomic inventories (Khan et al., 1977; Khan et al., 1985; Huq, 1986, 1988; Alam et al., 2006; Rahman et al., 2012; Rahman, 2013; Rahman et al., 2013; Rahaman et al., 2015; Shetu et al. 2018; Tabassum, 2015) were also performed in different urban and rural areas of this country. However, these studies do not provide specific data on the homestead forests or floras of the study area. A good of number studies (Bashar, 1999; Uddin et al., 2002; Alam et al. 2005; Masum et al., 2008; Kabir and Webb, 2009; Miah and Hussain, 2010; Alam, 2011; Muhammed et al., 2011; Muhammed et al., 2013; Islam et al., 2013; Rahman et al., 2013; Roy et al., 2013; Islam et al., 2015; Rahaman et al., 2015; Sajib et. al., 2016) were carried out on the homestead forests in different regions of Bangladesh. However, the homestead floras of Dhaka, Manikganj, Gazipur and Tangail regions are not yet studied. This study was carried out to provide basic and recent taxonomic information on the species of the class Magnoliopsida (Dicotyledons) extant in the visited homestead areas of Bangladesh. Materials and Methods The study area lies in Dhaka, Gazipur, Manikganj and Tangail districts, that are located in central Bangladesh, in between 23º38'-24º48'N and 89º41'-90º42'E and composed of an area of about 8067.97 sq km. This study was conducted during 2013 to 2018 based on a thorough taxonomic inventory involving 240 field trips to 1120 representative homestead areas belonging to 40 villages of 20 upazilas under the four districts in different seasons (Fig. 1). Following a preliminary reconnaissance survey, four categories of homesteads viz., old joint, old isolated, and new joint and new isolated, were selected from each district for better representation. The selected old homesteads were more than 20 years to 80 years old and the new ones were more than five years to less than 20 years old. The homesteads of each district were equal in number, more or less homogenous and from plain land areas to promote the reasonable comparision. Representative specimens with flowers and fruits were collected during the field trips. Routine herbarium methods (Jain and Rao, 1977) have been followed in collecting, preparing, pressing, drying, mounting, and storing the plant specimens. All plant specimens were identified through consulting with the experts, taxonomic descriptions and keys available in the relevant literature (Hooker, 1872−1897; Wu et al., 1995−2013), and matching with relevant voucher specimens preserved at Jahangirnagar University Herbarium (JUH), and Bangladesh National Herbarium (DACB). Nomenclatural information were verified through consulting TROPICOS (2010), The Plant List (2013), International Plant Names Index (2015) and the recent floras (Wu et al., 1995−2013; Watson et al., 2011). The families have been arranged following Cronquist (1981). The families Phyllanthaceae and Putranjivaceae, not included in Cronquist (1981)’s System, are placed besides their close family Euphorbiaceae. All genera and species are presented alphabetically. All voucher specimens are housed at JUH. The similarities in species composition in the homesteads of four districts have been measured following Jaccard coefficient (Jaccard, 1912). The threatened status of the species in the homsteads of the study area was recognized based on their existing population PRELIMINARY TAXONOMIC STUDY ON HOMESTEAD FLORA 39 size, distribution range, and regeneration in the area, collections, interviews with elderly local people, and consulting the relevent IUCN guidelines (IUCN Standards and Petitions Committee, 2019).

Results and Discussion This study recorded total 455 species of Magnoliopsida (Dicotyledons) under 302 genera and 78 families from the the visited homestead areas of Dhaka, Gazipur, Manikganj and Tangail districts (Table 1). Twenty three of the families were represented by single species each, 39 families by 2-10 species and only 13 families by 11-20 species. The homesteads of four districts 40 ROY AND KHAN Table 1.

Among these species, 47 were climbers, six vines and four parasites. These data indicate that the homestead areas of central region of Bangladesh still harbour a large number of Dicot species and they can serve as the hotspots of the flora and biodiversity of Bangladesh. The taxonomic enumeration of the species of dicotyledons in the homestead areas of the four districts reported by this study seems lower than the record (605 species) of Tabassum (2015). This is due to the reason that Tabassum (2015) studied this plant group of whole Gazipur district consists of homestead and different non-homestead areas, the total land area of this district is much higher than that of the 1120 homesteads of four districts under this study, and in these homesteads, a good number of the species were overlapping and common. Most of other relevant studies conducted in plain land areas of this country mention the taxonomic account of Angiosperm species instead of dicot species. The enumeration of Angiosperm species by few of these studies (Kabir and Webb, 2009) are relatively higher, whereas, that of few other studies (Begum et al., 2013; Islam et al., 2013; Muhammed et al., 2011, 2013; Rahman et al., 2009) are relatively lower than that of the dicot species by this study. In the homesteads of the study area, Fabaceae with 41 species of 28 genera was recognized as the largest family that was followed by Euphorbiaceae with 34 species under 19 genera and Asteraceae with 26 species belonging to 22 genera. Solanum L. and Lindernia All. with eight species each was found as the largest genus in the study area, which was followed by Ficus L and Euphorbia L. with seven species each, Persicaria Mill. with six species and Albizia Durazz., Diospyros L. and Piper L. with five species each. The composition and distribution of dicot species in the homestead areas of the four districts were remarkably variable. In the homesteads of Dhaka, Gazipur, Manikganj and Tangail districts, the occurance of total 283, 243, 285 and 223 species, respectively, was confirmed. Among these species, a total of 52, 35, 53 and 20 species were found to occur exclusively in the homesteads of PRELIMINARY TAXONOMIC STUDY ON HOMESTEAD FLORA 61 Dhaka, Gazipur, Manikganj and Tangail, respectively. Whereas, total 231, 208, 231 and 203 species, respectively of Dhaka, Gazipur, Manikganj and Tangail districts, were recorded as overlapping in the remaining three districts. Only 110 species were commonly found in the homesteads of four districts. The similarity between and among the four districts in species composition of their homesteads measured by Jaccard coefficient shows that (Fig. 2), it is more than 60% in between any two of these districts, whereas, it is only 41% if all of the four districts are considered. The highest similarity in species composition (72%) was found in between Gazipur and Tangail districts, and the lowest (63%) in Dhaka and Manikganj districts. Fig. 2. Similarity in species composition in homesteads of the four districts based on Jaccard coefficient (Jaccard, 1912). The study has recognized a total of 332 species from the homesteads of the study area of central Bangladesh as economically useful. The major categories of these economically useful species were medicinal (184 species), timber (34 species), fruit (38 species), ornamental (36 species), vegetable (30 species), fuel wood (26 species), oil (14 species), spice (five species) and fiber (eight species). Among the economically useful species of the study area, total 53 species were useful in two and seven species in three economic categories. Among these, at least 96 tree species (e.g. Albizia lebbeck, Alstonia scholaris, Aphanamixis polystachya, Barringtonia acutangula, Bombax ceiba, Lagerstroemia speciosa, Lannea coromandelica, Miliusa velutina, Polyalthia longifolia, Syzyzium cumini, Tamarindus indica, Tectona grandis, and Trema orientalis), used as wood or timber, are now native to Bangladesh. Moreover, a good number of medicinal (e.g. Abroma augusta, Azadirachta indica, Cinnamomum tamala, C. zeylanicum, Ficus racemosa, F. religiosa, Holarrhena antidysenterica, Moringa oleifera, Ocimum sanctum, Ricinus communis, Terminalia arjuna, T. belerica, T. chebula, Tiliacora acuminata, Tinospora crispa, Vitex negundo, and Zanthoxylum rhetsa) and fruit yielding (e.g. Aegle marmelos, Annona reticulata, A. squamosa, Artocarpus heterophyllus, Averrhoa carambola, Baccaurea motleyana, Carica papaya, Citrus grandis, C. limon, Dillenia indica, Diospyros peregrina, Flacourtia jangomas, Mangifera indica, Manilkara zapota, Elaeocarpus floribundus, Phyllanthus acidus, P. reticulatus, Psidium guajava, Punica granatum, Syzygium cumini, and Tamarindus indica) species, harboured in the homesteads of the study area, are also 62 ROY AND KHAN native to Bangladesh. The occurrence of a good number of timber and fruit species in the homestead areas of the study area is supported by Bashar (1999). But in contrast, the population of about 28% of the native tree species (e.g. Holarrhena antidysenterica, Terminalia belerica, T. arjuna, Diospyros montana, Pithecellobium dulce, Macaranga indica, Mallotus philippensis, Elaeocarpus tectorius, Piper peploides, Tabernaemontana dichotoma, Miliusa velutina, Diospyros peregrina) were found to be declining in the homestead areas of the four districts. This study has provided field data on the current status of seven threatened species, included in the Red Data Book of Vascular Plants of Bangladesh (Khan et al., 2001; Ara et al., 2013), in the study area (Table 2). The existing population size, number of localities, and estimated Extent of Occurrence (EOO) and Area of Occupancy (AOO) of these species were very narrow (Table 2). Moreover, all of these species were observed with poor regeneration and their localities were under the threats of continuous habitat destruction. Based on these facts, Abroma augusta (L.) L.f., Aniseia martinicensis (Jacq.) Choisy, Pterocarpus santalinus L.f. and Tournefortia roxburghii C.B. Clarke have been estimated as Critically Endangered (CE), Mucuna bracteata DC. ex Kurz and Rauvolfia serpentina (L.) Benth. ex Kurz as Endangered (E), and Andrographis paniculata (Burm.f.) Nees. as Vulnerable (V) in the homeatead areas of Dhaka, Gazipur, Manikganj and Tangail districts. Table 2.

The data provided by this study might be useful in planning, management, conservation and sustainable development of homestead plant genetic resources in Bangladesh. The increased human population and associated development activities in the last few decades has resulted directly in depletion of natural vegetation, which in turn increase the pressure on the homestead forest especially in the developing countries to meet various needs of the human beings (Alam et. al., 2005). This observation is found to be true in the homestead areas of the four PRELIMINARY TAXONOMIC STUDY ON HOMESTEAD FLORA 63 districts studied. Additionally, habitat fragmentation and depletion, intrusion of exotic (e.g. Parthenium hysterophorus, Mikania cordata, Chromolaena odorata, Acacia auriculiformis and Eucalyptus camaldulensis) and parasitic species (e.g. Cuscuta reflexa, Dendrophthoe falcata, and Helixanthera cylindrica), vegetation clearing, unnecessary firing, unplanned agricultural extension, over exploitation of natural resources, lack of awareness in the local people including the homestead owners, and lack of proper management and protection systems homestead forests etc. are also the functional threats to the homestead flora, especially the threatened and declining native plant species, of the study area. Therefore, appropriate planning, management strategies and measures, and awareness building programs should be effectively launched for the conservation of plant genetic resources in the homestead areas of this region. Performing studies on the natural regeneration, biogeography, and pollination, breeding and dispersal mechanisms of the threatened species threatened and declining native species of the region are very crucial for their sustainable conservation. Besides, effective attempts including the provision of incentives for involving the local people in conservation programs in the region is highly recommended.
