Kata kunci: Jambi, Freycinetia, Pandanaceae INTRODUCTION Nine species of Freycinetia Gaudich were re- ported for Jambi (Widjaja & Hidayat 2007). This number is almost as high as recorded previously by Stone (1970a), where he mentioned that there are 10 species occurred in Sumatera. During an inventory of this genus in Jambi, one more species was found and described here as a new species. The present article briefly discusses the nine species which have been written previously by Widjaja & Hidayat (2007) and Widjaja et al. (2009). A key to the nine species in Jambi, nomenclature, habitat, recent new notes of specific morphological characters and specimen examinations are provided. Many new specimens of Freycinetia for this study were collected by the first authors during an exploration of this genus around Sumatra. The col- lection were deposited in MEDA, a local university herbarium in Sumatera Utara, belongs to the Uni- versity of Sumatra Utara, Medan. MEDA is pro- posed to be a herbarium and written in the list of herbaria in Indonesia (Girmansyah et al 2006). IDENTIFICATION KEY TO THE SPECIES OF FREYCINETIA IN JAMBI 1. a.

FREYCINETIA ANGUSTIFOLIA Blume Freycinetia angustifolia Blume, Rumphia 1: 157. t. 43, f. 1–7. 1835. —Lectotype: Java, G. Seribu, Blume 841 (L, holo, sh. 908. 164–106).

Philipp. Bot. 3: 1114. 1911. —Type: Capiz Province, Mt. Magel- lanes (Giting-giting), May 1910, Elmer 12426 (FI, holo n.v.; PNH, lost, EDINB n.v.). Distribution. Malay Peninsula (Johor, Malacca, Negeri Sembilan, Penang, Perak, Selangor), Singa- pore, Sumatra (It is widely distributed in Jambi Province), Java (G. Salak), Borneo (Sarawak, Ban- jarmasin), Philippines (Sibuyan). Habitat. Littoral zone, primary and secondary for- est, roadsides, swampy areas, lowlands, rarely up to 1800 m altitude. Notes. This species was first described by Blume from Java and again by Ridley as a new species from the Malay Peninsula, which was duly syn- onymised by Stone (1970b). Stone (1970b) men- tioned that 1–3, rarely 4, very rarely 5 stigma re- main, but in the present study it was found that the stigma remain are 1–6, very rarely 7. Also, he men- tioned that the outermost bracts would be dark to pale yellow or yellow-orange, sometimes flecked with red on the inner surface. However, in fresh plants in the field, the outermost bracts are pale green to greenish with green tips. This species is characterized by its linear leaves, basal leaves with spines, leaf auricles laciniate or finely fibrous with 2 (or 3) horizontal septa across the auricle width, and racemose inflorescences.
