INTRODUCTION Sumbawa is an island within the string of is- lands stretched eastward from Bali to Timor known as the Lesser Sunda Islands. Unlike the neighbour- ing Java, the pandan flora in any of these islands remains largely unknown. The nature of the pan- dans in the Lesser Sunda Islands is illustrated by inadequate information. Prior to this current study, there have been only two records ever published; Martelli (1910) and Markgraf (1929). Martelli (1910) proposed a new species from Timor, F. timorensis, whereas Markgraf (1929) proposed F. lombokensis from Lombok. Both species are en- demics and so far are known only from the types. Other information to be mentioned is brief accounts (supported by two black and white photos) by Rensch (1930) on Freycinetia and Pandanus (P. odoratissimus) from Flores. The information of F. urvilleana of Decaisne (1853) has been discarded. This species was previously regarded by Solms (1878; see also Warburg, 1900) as collected from the area of Vavao in Timor. However, Vavao is actually a district in the Guadalcanal Island in the Solomon Archipelago, one of islands in Oceania that was visited by Hombron and Jacquinot during their 1837-1840 collecting trips (see Decaisne, 1853). Neither Hombron nor Jacquinot was known to visit Timor during that period. Despite extensive explorations and collections made by Kostermans and his colleagues from Herbarium Bogoriense (BO) in Sumbawa (see Kostermans, 1963), the pan- dan flora of Sumbawa is still in doubt. This current study is aimed to provide an up to date information on the pandan flora of Sumbawa. The exploration was proceeded in the Batulanteh area in the west- ern side of the island. RESULTS AND DISCUSSIONS Two species of Freycinetia and two species of Pandanus are recorded from the Batulanteh vi- cinity in West Sumbawa, in which one species de- scribed here is a new species and named Freycinetia sumbawaensis A.P. Keim & M. Rahayu. 1. FREYCINETIA INSIGNIS Blume –– Fig. 1. Freycinetia insignis Blume (1835) 158, t. 42. –– Type: Java, West Java, Bogor (then Buitenzorg), Gede Moun- tain, Blume s.n. (Lectotype:L).

Rahayu. 2010] 153 KEIM & RAHAYU: Pandanaceae of Sumbawa, West Nusa Tenggara, Indonesia recorded from mountainous areas in western side of the island such as Burangrang, Gede, Pulasari, Salak, and Tangkuban Prahu (see Blume 1835). In Bali this species is abundant at Bedugul forest and adjacent areas at 1,300 m altitude. In Lombok this species is found abundantly at Passuk forest in East Lombok at about 1,450 to 1,650 m altitude. In Sum- bawa, F. insignis is conspicuously found in hill slopes at about 1,500 to 1,700 m altitude, never lower than that. Vernacular name. Sampian (Bali, Bedugul dia- lect), Klipan (Sumbawa). Uses. The mature cephalium is said to be eaten by birds. Notes. Local people mentioned that the “flower” is white tinted with red or deep red. Obviously what they do mean by “flower” is actually the bract. Un- fortunately, the bracts were not available by the time the collection (A.P. Keim 1265) was made. Until the specimen with bracts is collected this taxon is identified here as belonging to F. insignis based on the information on the colour of bract. The unmistakably white tinted with deep red to red- dish-purple colour bract is a distinctive field charac- ter for F. insignis. Furthermore, there is no single distinctive morphological character that can be used to separate this taxon from F. insignis. Specimen examined. INDONESIA, Lesser Sunda Islands, Bali, Bedugul, Mt.

Gracilis scandens usque ad 20 m altum, ca 1 cm dia- metro, viridi; infructescentia terminale, binata vel ter- nata; stigma simper 1, nigrum. –– Typus: INDONESIA, Lesser Sunda Islands, Nusa Tenggara Barat, Sumbawa, West Sumbawa, Batulanteh, Batudulang, Brang Tampu, A.P. Keim 1270 (BO!– Holotype), 16 Aug. 2009. Slender climbing pandan, climbing up to 20 m high. Stem slender, ca. 1 cm diameter, green. Leaf ellipse or oblong-ellipsoidal, ca. 10 cm long, ca. 1.5 cm wide, acuminate apex, with minute spines; ad- axial surface green, glabrous, shiny; abaxial surface light green, glabrous; auricle tapered, glabrous. In- fructescence terminal, binate (2) or ternate (3), ca. 4.5 cm long; peduncle very short, less than 1 cm long; pedicel green, glabrous, 1.5–2 cm long. Cephalium green, said to be red when ripe, globose to rather elongated globose close to ellipse, ca. 2.5 cm long, ca. 1.5 cm wide; stigma 1, black. Etymology. The epithet means from Sumbawa, which refers to the island where the type was col- lected. Distribution. Endemic. Habitat. Lower tropical rainforest to montane for- est. The species is commonly found along streams or riverbanks at 400 to 950 m altitudes or in hill slopes at 1,500 to 1,700 m altitudes. Vernacular names. Klipan, melung (Sumbawa). Uses. As strings. Mature cephalium is said to be eaten by birds. Notes. In general appearance F. sumbawaensis very much resembles F. scandens except for the number of stigma (Table 1). Freycinetia sumbawaensis al- ways has berry consistently with 1 stigma, while F. scandens always has 2 to 4 stigmas, usually 2, but never less than 2. Freycinetia species with a fairly globose cephalium with number of stigma 1 is ex- tremely rare. There are only two species known with that character; F. forbesii, and F. oblanceolata. However, these species have 1 to 2 stigmas (Table 1). Freycinetia forbessii are commonly found with one stigma, rarely two (see Ridley, 1886). Indeed, apart from differences in number of cephalia per infructescence and cephalium dimension the two species are very similar. Ridley (1886) suggested that F. forbesii and F. scandens as closely ally. The result of this current study is in accordance with Ridley and adding F. sumbawaensis into the alli- ance. Stone (1967) mentioned that F. angustissima possesses berries with numbers of stigma 1 to 3. Observations made on specimens in BO indicate that F. angustissima possesses berries with numbers of stigma 2 to 3. The protologue itself (see Ridley, 1886) did not mention about the number of stigma.

Rahayu. 2010] 155 KEIM & RAHAYU: Pandanaceae of Sumbawa, West Nusa Tenggara, Indonesia Ridley described that the infructescence consists of 1 to 2 cephalia (he noted: “capitula feminea singula vel bina”) and it is allied to F. angustifolia. Frey- cinetia angustifolia is known to possess numbers of stigma 3 to 4. Prior to the collection made in this current study, a specimen was collected by Mrs. Rensch (Frau Rensch 907), who accompanied her husband in the 1924-1925 German exploration to the Lesser Sunda Islands. Although Mrs. Rensch clearly mentioned that the cephalium (she noted as fruit) was kept in spirits, but the spirit collection was not found in BO. A taxon mentioned as F. meijeri by Stone (1967) was regarded as having berries with numbers of stigma 1. Apparently the name has never been val- idly published, and became a nomen nudum. Evi- dently, Stone (1970) did publish the taxon but as a variety of F. robinsonii Merr., that called F. robin- sonii Merr. var. meijeri B.C. Stone. In contrast to his previous opinion when mentioning F. meijeri, F. robinsonii var. meijeri is described as possessing berries with number of stigmas 2 to 3. Specimen examined.

Leaf lanceolate-elongate, 240–250 cm long, 5.5–6 cm wide, acuminate apex, margin with minute-sharp spines; adaxial surface green, glabrous, adaxial ventral pleats absent; abaxial sur- face light green, glaucous white, recurved spines absent; leaf sheath short, ca. 5 cm long, white. In- fructescence terminal, hanging, consists of 7–8 cephalia; 1 infructescence 100–101 cm long; pedun- cle ca. 50 cm long, green, glabrous; rachis 50–51 cm long. Cephalium elongated-ellipsoidal, sausage- like, trigonal, dull orange when mature, 17–24 cm long, 13–16 cm circumference. Drupes compactly arranged, ca. 1 cm long; stigma short, oblique on the ventral side of pileus, flat, slightly bifurcate. Distribution. Java and Lesser Sunda Islands. Backer (1925) mentioned that this species occur only in Java and Bali. In Java, P. faviger is only so far found in Lamongan (see also Stone 1972) and stored as the type. In other words, new collection has never been made. Habitat. Humid montane forests at altitude 1,000 to 1,800 m. In Sumbawa this species is abundantly found at altitude 1,700 to 1,800 m. Vernacular name. Panan layun (Sumbawa). USES. The hanging prop-roots are boiled and drink as an aphrodisiac and also believed can increase the size of male sexual organ. Notes. People at Batudulang named this species “Panan layun”, which means forest pandan. Appar- ently, they have never used or harvested the leaves. Pandanus faviger in Sumbawa is always found at altitude above 1,000 m dominating the humid mon- tane forest of Batulanteh and adjacent areas. This finding is in accordance with Kostermans (1963).

Beach, mangrove, from seaside up to 500 m altitude. Vernacular name. Pandan, pandan mayit (Sumbawa). Uses. The leaf is very aromatic (odorous) and used by the local people at Batudulang and adjacent areas in funeral procession. Leaf is also used for mats. Notes. Only one cluster of about five individuals is found in Batudulang village. Batudulang is located at around 400 m altitude, thus still within the range of altitude tolerated by P. odoratissimus. The spe- cies could not be found anywhere else in Batudu- lang and adjacent areas. Local people mention that the plants are cultivated and have not yet been seen in fruiting. Nevertheless, inflorescences were once observed and the inflorescences are said to be odor- ous and the bracts are white; thus match the field description for P. odoratissimus. Prior to this current study, there has been no collection of P. odoratissimus from Sumbawa, thus a new record. In fact, previously Herbarium Bo- goriense possesses only three specimens of P. odo- ratissimus (labelled as P. tectorius) from the entire Lesser Sunda Islands. These findings are regarded here as quite surprising concerning the fact that P. odoratissimus is undoubtedly the most wide-spread species in the genus Pandanus. Specimen examined.
