Judd2 ABSTRACT A floristic and vegetational survey of two recently established national parks in the poorly known mountains of southern Haiti, i.e. Parc National Pic Macaya (in the Massif de La Hotte) and Parc National Morne La Visite (in the Massif de La Selle), clearly documents the rich and highly endemic nature of the tracheophyte (especially angiosperm) flora of the parks, and confirms EL Ekman's early reports of the region's flora. This study resulted in the recollection of most of the region's described endemic species, along with the discovery of several new angiosperms, i.e. Wallenia formonensis, Ilg blancheana, Micropholis polita subsp. hotteana, Mecranium revolutum, Meriania parvifolia, M. brevipedunculata, Miconia macayana, Ossaea woodsii, Lobelia hotteana, Salvia sp., Rhytidophyllum sp., Pilea sp., and Ditta sp. One new combination, Garcinia barkeriana, is made. A total of 470 species of tracheophytes (including 367 angiosperms, but excluding orchids), 99 mosses, and 63 liverworts was collected in Parc National Pic Macaya, and of these, 136 vascular plants (ca 29%) are endemic to Hispaniola. The vegetation of the park may be divided into two major types. A very diverse wet forest on limestone occurs from ca 800 to 1250 m alt. At higher elevations this forest is replaced by a complex mosaic of pine forest and cloud forest, both of which contain many local endemics. A total of 325 species of tracheophytes (including 262 angiosperms, but excluding orchids), 76 mosses, and 19 liverworts was collected in Parc National Morne La Visite, and of these, 112 vascular plants (ca 34%) are endemic to Hispaniola. The plant communities occurring in the La Visite region may be placed in two general categories: pine forest and cloud forest. The former occupies the bowl-shaped plateau of the Massif de La Selle while the latter occurs on the steep more or less north facing slopes along the edge of the plateau and in the major ravines dissecting it. 1 This paper is Florida Agricultural Experiment Station Journal Series No. 7652. 2The author is an Associate Professor of Botany, University of Florida, Gainesville FL 32611.

RESUMEN Se presenta un estudio floristico y de vegetaci6n de dos parques nacionales recidn establecidos en las serranias poco conocidas del sur de Haiti, o sean Parc National Pic Macaya (en el Massif de La Hotte) y Parc NatiOnal Morne La Visite (en el Massif de La Selle). El estudio documenta nitidamente la riqueza y la endemicidad de las traque6fitas (esp. las angiospermas) de los parques y confirma los informes antiguos de E.L Ekman sobre la flora de la regi6n. En el muestreo se recolectaron la mayoria de las especies end6micas descritas, y a la vez se encontraron varias angiospermas nuevas, o sean Wallenia formonensis, Ilex blancheana, Micropholis polita ssp. hotteana, Mecranium revolutum, Meriania parvifolia, M. brevipedunculata, Miconia macayana, Osaea woodsii, Lobelia hotteana, Salvia sp., Rhytidophyllum sp., Pilea sp., y Ditta sp. Se publica una combinaci6n nueva, Garcinia barkeriana. En el Parc National Pic Macaya se han colectado un totaI de 470 especies de traque6fitas (incluyendo 367 angiospermas, pero excluyendo las orquideas), 99 musgos y 63 hepdticas, y de estas, 136 traque6fitas (aprox. 29%) son end6micas de Hispaniola. La vegetaci6n del parque se puede dividir en dos tipos principales. Una selva h6meda en Diedra caliza muy diversa se encuentra de aprox 800 a 1250 metros de altura. A mayores alturas esta selva se reemplaza por un mosaico complejo de pinar y selva nebulosa, ambas con muchas especies end6micas locales. En el Parc National Morne La Visite se han colectado un total de 325 especies de traqu6fitas (incluyendo 262 angiospermas, pero excluyendo las orquideas), 76 musgos y 19 hepdticas, y de estas, 112 traque6fitas (aprox. 34%) son end6micas de Hispaniola. Las comunidades vegetales de la regi6n de La Visite puederi clasificarse en dos categorias generales: pinar y selva nebulosa. La primera se encuentra en la meseta c6ncava de Massif - de La Selle, mientras que la segunda se encuentra en las laderas empinadas nortefias por el borde de la meseta y en las barrancas principales de la meseta. Las selvas de ambos parques estan sujetas a tala y quema por los moradores de la region. Es obligatorio proteger Ios sitios selvdticos que quedan en los parques para con5ervar Ias muchas especies enddmicas y la belleza natural de la regi6n.

Thus, the island's flora is quite diverse (see Urban 1920-21, 1923; Barker and Dardeau 1930; Ciferri 1936; Moscoso 1943; Howard 1973). In spite of this diversity, some areas of Hispaniola have been collected relatively poorly. No complete Flora of either 4 BULLETIN FLORIDA STATE MUSEUM VOL. 32(1) tracheophytes (i.e. vascular plants) or bryophytes (i.e. mosses, liverworts, hornworts) exists, although available currently are a generic Flora, i.e. Isa Flore D'Haiti (Barker and Dardeau 1930), a checklist of seed plants, i.e. Catalogus florae Domingensis (Moscoso 1943; with supplement, Jim6nez 1966), and treatments for certain groups, i.e. Flora of Hispaniola: Dart 1. Celastrales. Rhamnales. Malvales. Thvmeleales. Violales (Liogier 1981) and La Flora de la Espaftola II. III. and IV (Liogier 1983, 1985, 1986). Urban's Flora Domingensis (1920-21) and Pteridoljhvta Domingensis (1925) are also useful. In addition, important information on the vascular flora of the island is contained in a series of papers by Urban (1921, 1926a, 1926b, 1927, 1928, 1929a, 1929b, 1930, 193la, 193lb) and Christensen (1938) based on the collections of Erik L. Ekman, and in Urban's Svmbolae Antillanae (1898- 1928). A preliminary list of mosses of Hispaniola has been published (Buck and Steere 1983); other useful papers dealing with Hispaniolan bryophytes include Muller (1898), Williams (1930), Thdriot (1944), Arnell (1956), Crum and Steere (1958), Crum (1965), and Judd (1980). Relatively few tracheophyte or bryophyte groups occurring in Hispaniola have been monographed recently and there is a great need for increased monographic study of neotropical groups. Vascular Floras of the island are being prepared simultaneously by Alain H. Liogier (of the Botanic Garden of the University of Puerto Rico, at Rio Piedras, Puerto Rico) and by Thomas A. Zanoni (of the Jardin Botanico Nacional, Santo Domingo, Dominican Republic) and contributors; William R. Buck (of the New York Botanical Garden) is working on a bryophyte flora of the West Indies. A very useful annotated bibliography of the flora and vegetation of Hispaniola is, given by Zanoni, Long,and McKiernan (1984). The diverse and highly endemic tracheophyte and bryophyte floras of the high elevations of the mountains of southern Haiti are among the most poorly known of the island of Hispaniola, and two Haitian national parks, i.e. Pam National Pic Macaya (in the Massif de La Hotte) and Parc National Morne La Visite (in the Massif de La Selle) have been established recently in this region (Fig. 1). The area designated as Parc National Morne La Visite is located 22 km south of Port-au-Prince in the area of latitude 18' 20' 30" N and longitude 72 ' 20' W. The park is situated along the crest of the Massif de La Sdk between Morne d'Enfer (1900 m) and Morne Kadeneau (2155 m). The highest spot in the park is Pic Cabaio (2282 m). The boundaries of the park have not been officially designated, but the official size of the park is 2000 hectares (Woods 1986). Access to the park is via the mountain road from Port-au-Prince via Furcy and Ca Jacques, a distance of ca 55 km, and normally takes ca 4 hrs to drive. Parc National Pic Macaya is located 36 km northwest of Les Cayes and 195 km west of Port-au-Prince at latitude 18' 21' N and 74' 01' W.

The park also includes the rocky plain south of Pic Formon (Plaine de Formon and Plaine de Deron--mainly agricultural areas) as well as - the karst hills along the southern boundaries of these plains, i.e. Bois Formon. Exact park boundaries have not been established; the official size of the park is 2000 hectares (Woods 1986). Access to Pam National Pic Macaya is difficult. The journey is via the route to the southwest from Port-au-Prince passing through Les Cayes. Beyond Les Cayes the route is via a gravel road 6 BULLErIN FLORIDA STATE MUSEUM VOL. 32(1) to Le Duc and then a rough dirt road to Le Pretre that crosses the Rividre l'Acul. From Le Pretre the route ascends to the plateau of the Plaine de Formon by a series of sharp switchbacks to the town of Les Platons. At this point it is necessary to hike for ca 10 km across the southern edge of the Plaine de Formon through Marche Sous Bois to Ville Formon, an agricultural community just south of the park, although a poor quality dirt road has been constfucted recently from Les Platons to Ville Formon. Since 1983 both parks have been under the administration of the Institut National Haitien de la Culture et des Arts (INAHCA) and the Ministere de l'Agriculture, des Ressources Naturelles et du Developpement Rural (MARNDR). This preliminary floristic study of the two parks was undertaken as part of a larger study of the systematic biology, ecology, and geology of these parks by the Florida State Museum (see Woods and Harris 1986; MacFadden 1986). The first botanist in the Morne Formon/Pic Macaya region (Parc National Pic Macaya, Massif de La Hotte) was probably L. C. Richard (Dod pers. comm.), who collected in the area in the late 1700s. The next and most important plant collectors in the Morne Formon/Pic Macaya region were Erik L. Ekman and Henry D. Barker, who visited and collected in the area from December 1926 to January 1927, and climbed Morne Formon; the results of this fascinating excursion are presented in an article by Ekman (1928). The many new species resulting from their collections were described mainly by Ignatius Urban or Urban and Ekman. The valuable field work of Ekman and Barker in the Massif de La Hotte is commemorated in the names of several distinctive endemics of this region (see lists). A xerographic copy of Ekman's field notes (University of Florida herbarium, FLAS, library; original set at Swedish Museum of Natural History, S) has also been studied, and reveals (along with Ekman's published account) a fairly detailed picture of the flora of the region as it existed in the 19205. Erik Ekman again collected in the high elevations of the Massif de La Hotte and climbed Pic Macaya from the north (Morne La Hotte, above Les Roseaux) in September 1928. Leslie R. Holdridge (former Division Manager, Pine Forest Project, Haiti) botanized on Morne Macaya (to near the peak) in February 1941. The natural history of the Massif de La Hotte is outlined by Dod (1984), who comments briefly on the distinctive and highly endemic flora of the region. Donald D. Dod (of the Jardin Botanico Nacional, Santo Domingo, Dominican Republic) has botanized in the region on several occasions between 1981 and 1984 and has prepared a report on the indigenous orchids (Dod and Judd 1986). Erik L. Ekman was also the most important plant collector in the Morne La Visite/Pic Cabaio region (Parc National Morne La Visite, Massif de La Selle). Ekman botanized in this region on several occasions in 1917 and the 1920s. Others who collected either in localities now within the La Visite park JUDD: FLORISTIC STUDY HAITIAN NATIONAL PARKS 7 or in adjacent regions include: W. Buch, Padre E. Christ, and Padre L. Ricarda; see Moscoso (1943) for brief outlines of their activities. More recently (Nov. 1982) W. Buck, T. Zanoni, and M. Mejia also have collected in this area. The work of these botanists is commemorated in the names of many plants occurring in the Massif de La Selle (see list). A brief description of Ekman's collecting experiences in the Massif de La Selle has been published (Ekman 1926), and additional information on the diverse and highly endemic flora of this region is present in Ekman's personal field notes (S, copy at FLAS, library). Holdridge's (1947) and Marie-Victorin's (1943) accounts of the similar pine forests of the Morne des Commissaires are also of interest. From a study of published accounts of the flora of the localities now contained in the Pic Macaya and Morne La Visite National Parks, and from Ekman's personal field notes, it appears that most of the members of the vascular flora present in the 19205 still occur within (or adjacent to) the two national parks--despite the extensive human-caused disturbances in some localities. Noteworthy species collected in these areas by Ekman (unpubl. field notes) but not recollected in this floristic study are listed in Tables 1 and 2. It should be noted that these lists are not complete but stress endemic and/or conspicuous woody taxa. Additional collecting in the parks will likely reveal the presence of these, as well as other, species. In addition, two endemic bryophytes described from the high elevations of the Massif de La Hotte have not been recollected; these are: Hymenostomum castaneum Crum and Steere and Campylopus haitensis Th6r.

Last, I thank my wife, Beverly, for her understanding and patience throughout this study. ENDANGERED SPECIES Top priority for protection should be given to species endemic to Hispaniola, and especially to those endemics with ranges restricted to the Massif de La Hotte and/or the Massif de La Selle (or with more local distributions within these mountain ranges). Species very susceptible to disturbance (e.g. Juniperus ekmanii) should be given special concern. Ecological/biological studies of these species are urgently needed; unfortunately very little is known beyond the most basic taxonomic informhtion for most plant species endemic to these regions. Junipents ekmanii may be the woody species most in danger of extinction. This species has a very limited range, and does not sprout vegetatively after fire or cutting, both very common in the region. Thus, in many parts of the La Visite park (even places seemingly little disturbed and with diverse native vegetation) the species is present only in the form of dead stumps and logs. The species is surviving in the Tete Opaque region, and urgent efforts should be made to protect the few remaining individuals. Other endemics that seem to be rare or very restricted in distribution within the parks include: Hypen~cum millefolium, Miconia nkidissima, Gesnen'a hypoclada, Smplocos hotteana Urb. & Ekm.
