D., SUKSATHAN, P., BORCHSENIUS, F. 2010. Marantaceae in Sulawesi. Reinwardtia 13(2): 213–220. — Six species of Marantaceae occur in Sulawesi. We present a key to the species together with a taxonomic treatment with notes on species delimitation, distribution, habitat and ecology, vernacular names and uses. One species endemic to Sulawesi and not covered by any contemporary publication, Phrynium longispicum (Warb. ex K. Schum.) Suksathan & Borchs. is described and neotypified. Donax canniformis (G. Forst.) K. Schum., Phrynium pubinerve Blume, Phrynium robinsonii (Valeton) Suksathan & Borchs, Stachyphrynium latifolium (Blume) K. Schum. and Stachyphrynium repens (Körn.) Suksathan & Borchs. are also reported from Sulawesi and characterized. For the two last species these occurrences represents an extension of their previously known range across Wallace's line.

INTRODUCTION The Marantaceae includes about 23 genera and 550 species worldwide (Andersson, 1998). Eight genera and an estimated 55 species occur in tropical Asia (Suksathan et al., 2009). Over the last few years, several publications have helped clarify the taxonomy of the West Malesian species (Clausager & Borchsenius, 2003; Suksathan & Borchsenius, 2003, 2005, 2008; Poulsen & Clausager, 2004; Clausager et al., 2006; Suksathan et al., 2006, 2010), but the Marantaceae occurring east of Wallace's line are still very poorly documented. Prior to our recent fieldwork, the most recent account of the Marantaceae of Sulawesi was by Koorders (1898) who, in his account of the flora of north Sulawesi, listed three species: Maranta dichotoma Wall. [a synonym of Schumannianthus dichotomus (Roxb.) Gagnep. misapplied to Donax canniformis (G. Forst.) K. Schum.]; Maranta indica Tussac [a synonym of the widely cultivated root crop M. arundinacea L.] and Phrynium capitatum [a synonym of P. pubinerve Blume which is probably a misidentification of P. longispicum]. In this paper we provide a taxonomic account of the Marantaceae of Sulawesi. The data presented REINWARDTIA 214 [VOL.13 are based on field work carried out in 2008 and 2009 and examination of herbarium specimens found at AAU, BO, E, L and S. The endemic Phrynium longispicum (Valeton) Suksathan & Borchs., for which no up-to-date description exists, is described in full and neotypified. For the remaining five species which are already covered by detailed descriptions in the literature we provide only a brief characterization. Generic delimitation follows Suksathan et al. (2009). Descriptive terminology regarding inflorescence structure follows Clausager & Borchsenius (2003). The term 'special paraclade' refers to the basic flower-bearing structure of the inflorescence while 'fertile bracts' refer to those bracts that subtend a special paraclade.

Distribution. Endemic to Sulawesi. Habitat and ecology. In disturbed primary forest and swampy forest. Alluvial flat land to lower hill slopes. Recorded up to 1,075 m elevation. Vernacular name. Polipot (Uji 4496). Uses. Ornamental plants (Uji 4496). Notes. Both syntypes cited in the original REINWARDTIA 216 [VOL.13 description of the species are lost. As neotype we have chosen a recent collection with both flower material in alcohol and fruits (Poulsen et al. 2815) from Boyong; the same locality as one of the syntypes, Warburg 15739. This neotype well agree with the protologue of the species. Phrynium longispicum was included in the phylogenetic study by Suksathan and Borchsenius (2009) under the accession name Phacelophrynium sp. 1 (DNA extracted from the specimen Vogel & Vermeulen 6721, L). The results show that P. longispicum is more closely related to Philippine taxa such as Phrynium interruptum than to the New Guinea clade of Phrynium (including species such as P. giganteum, P. kaniense and P. macrocephalum).

Javae: 37. 1827., For a full nomenclatural account see Suksathan & Borchsenius (2005). Rosulate herb, 0.7–3.5 m tall. Leaves 2–3 per shoot; lamina 23–82 × 9–30 cm, glabrous except for small hairs around the midrib. Inflorescence terminal on a leafy shoot, erect, usually appearing to protrude from the petiole of an accompanying leaf, capitate, 4–8 cm in diameter; bracts sheathing the inflorescence quickly withering apically and dissolving into a decaying fibrous mesh; flower pairs 2–4 per special paraclade. Flowers pinkish white, ca. 1.8 cm long; sepals ca 10 mm long; corolla tube 4–5 mm long; outer staminodes 2, their petaloid lobes 3–4.5 mm long. Fruits bright red, elongate to triangular, ca 15 × 10 mm, dehiscent; seeds 3, grey, with a small aril. Distribution. Widely distributed in SE Asia, from India to Burma, Thailand, Laos, Vietnam, Cambodia, Peninsular Malaysia, Sumatra, Java, Borneo, the Philippines and New Guinea. Habitat and ecology. This species seems to prefer a moderate level of habitat disturbance, and is often found growing next to streams, roads and trails, or even in the understorey of old rubber plantations. Vernacular name. Onese (Tolaki language) (A.D. Poulsen et al. 2791). Uses. Juice from the stem is used to cure irritant eyes; the stem is used for weaving or to keep roof thatching in place (Poulsen et al. 2791). Notes. A widespread and variable species found throughout SE Asia. It is recognized by the combination of red fruits, capitate inflorescence with tattering inflorescence bracts, and flowers with two outer staminodes. Taxonomic treatments for Borneo and Thailand, with full botanical descriptions, are provided by Clausager and Borchsenius (2003) and Suksathan & Borchsenius (2008), respectively. Herbarium material of this species is often identified as Phrynium capitatum Willd. which, however, is an illegitimate name synonymous with P. pubinerve (see Clausager & Borchsenius 2003).

Fertile shoots with 15–45 cm tall stem. Sheath of basal leaf ca. 120 cm long, petiole 10 cm long, blade 40–50x17–25 cm. Inflorescence with peduncle 10–20 mm long measured from node of subtending leaf, primary inflorescence branches 2–4, the proximal ones separated by internodes of 30–65 mm long. Primary bracts to 25 mm long, persisting. Flower pairs 2–3 per special paraclade. Flowers to 25 mm long; sepals ca. 7 mm long; corolla tube ca. 16 mm long, petal lobes elongate, 10–12 mm long; outer staminode 1, linear, ca. 7 mm long; callose staminode with an elliptic, emarginate petaloid lobe, ca. 6 mm long. Fruit ca. 10x5 mm; seeds 1(–2). Distribution. Endemic to the Moluccas and Sulawesi. Habitat and ecology. Not much is known, but it REINWARDTIA 218 [VOL.13 seems to occur mostly at low elevations. Notes. This species is known from several collections in the Moluccas and a single record from Sulawesi. We have not found this species in the field and we have had no access to fresh or pickled flower material. The above description of flowers is based on Valeton's (1917) protologue. According to Valeton, the flowers of P. robinsonii are markedly smaller (25 mm long) than those of P. longispicum (ca. 40 mm long). The inflorescence structure also seems to be different in the two species, more elongate and with fewer branches per node in P. robinsonii. The limit between the two species should, however, be reinvestigated as more material becomes available. Specimens seen from Sulawesi.

Widespread in the west Malesian region, from southern Thailand and Peninsular Malaysia to Java, Sumatra, Borneo and Sulawesi (first record). Habitat and ecology. Small forested hill in garden area. Notes. The species is readily recognized by its spicate inflorescences, with distichous fertile bracts, that arise on separate shoots from the leaf-bearing ones. Detailed botanical descriptions based on material from Borneo and Thailand, respectively, are provided by Clausager & Borchsenius (2003) and Suksathan & Borchsenius (2008). The single recent collection (Poulsen et al. 2805) represents an extension of the known range of the species across Wallace's line. This species is sometimes cultivated in Malaysia and it is difficult to rule out entirely that it has escaped from cultivation. The plants were, however, collected in a more or less primary forest patch amongst cocoa plantations etc. far from the nearest village. The locals also thought it was native. Lacking collections of this species from several primary forest sites nor evidence of cultivation, we cannot be certain whether it has been introduced. Specimens seen from Sulawesi. Central Sulawesi. Samawati (1°1'31.2''N, 121°36'16.2''E), 40 m, 21 February 2009, flowering, Poulsen & Kinho 2805 (AAU, BO). 6. STACHYPHRYNIUM REPENS (Körn.) Suksathan & Borchs. Stachyphrynium repens (Körn.) Suksathan & Borchs. , Taxon 54 (4): 1086 (2005). — Phrynium repens Körn., Bull. Soc. Imp. Naturalistes Moscou 35(1): 103 (1862). – Type: Java, Göreng 408 (Turczaninow herb., KW?, LE?). Stachyphrynium jagorianum (K. Koch) K. Schum. in Engler, Pflanzenr. 4(48): 48. 1902. For a full nomenclatural account see Suksathan & Borchsenius (2005) Rosulate herb, to 55 cm tall, frequently forming large colonies on the forest floor. Leaves 1–3 per shoot; lamina elliptic to oblong, acute to acuminate, 10–20x3.5–5.5 cm, green to dark green above, with more-or-less pronounced darker green stripes following the major veins, pale below, glabrous or pubescent. Inflorescence interfoliar, erect, usually simple; peduncle 5–14 cm long; spike 2.5–7.5 cm long with 3–6 distichous fertile bracts; flower-pairs 2 per special paraclade but usually only 1 pair develops. Flowers white, ca. 10 mm long; sepals to 2.5 mm long; corolla tube 13–18 mm long. Fruits broadly ellipsoid to obovate, to 4x5 mm; seeds 1–2, with a large bifid aril. Distribution. Indo-China, Thailand, Peninsular Malaysia and Indonesia: Sumatra, Java and Sulawesi (first record). Not recorded in Borneo. Habitat and ecology. Forest-savanna mosaic on sandy soil. Notes. Easily recognised by its small size and the dark green oblique bands on the upper side of the leaves. A detailed botanical description of this species is provided by Suksathan & Borchsenius (2008). This record represents an extension of the known range of the species across Wallace's line. Only one collection is known from Sulawesi (Poulsen et al. 2797) but we found S. repens at several localities south of Kendari and it appears to have dispersed to SE Sulawesi a long time ago. Specimens seen from Sulawesi. Southeast Sulawesi.
