Abstract

This current study of Freycinetia was carried out in Timika, West Papua. Results indicate that species vary in both morphological characters and habitat preferences. Timika is unique as only in this area species with highest number of segments in a berry and of stigmatic remains are found. Exceptional characters regarding to auricles, areolas, and stigmatic remains are observed in many species in this area. The result of this current study suggests that the ability of species to adapt to the widespread forest disturbances in Timika leads to their differences in morphological features compare to other Papuan species. Subsequently, seven new species are described here.

Abstract

SINAGA, N. I., MEGIA, R., HARTANA, A., KEIM, A. P. Ecology and distribution of Freycinetia Gaud. (Pandanaceae; Freycinetoidea) in Indonesian New Guinea. Reinwardtia 13(2): 189-197. - The study mainly concerns with the species of Freycinetia that occurs in the Indonesian New Guinea, including the provinces of Papua and Papua Barat. The study indicates that almost all species of Freycinetia in the Indonesian New Guinea prefer high humidity and abundantly occur along rivers, except for the members of the group of species with imbricate leaves, which inhabit also secondary forests. Futhermore, the members of this group have never been found within the range of 1700 to 3000 m altitudes. This highest range of altitudes is specifically occupied by the members of the groups of species with semi imbricate and grass-like leaves. The costal forests are inhabited by the groups of species with semi and non imbricate leaves. Indonesian New Guinea shares many species with Papua New Guinea, except for the members of the group of species with semi imbricate leaves, which are more common in Indonesian New Guinea than in Papua New Guinea. On the contrary, the members of the group of species with grass-like leaves are more common in Papua New Guinea and becoming rare toward the Indonesian site and becoming absent in the Vogelklop (Birds head), except for F. polyclada which is commonly found in Sorong. Indonesian New Guinea possesses 34 species exclusively distributed in the area, while Papua New Guinea has 72 species. The two areas share 52 species. Only five species have extra New Guinean distributions, i.e. F. excelsa, F. funicularis, F. marginata, F. percostata, and F. scandens.

Abstract

SINAGA, N. I. 2010. Two new species of Freycinetia (Pandanaceae) from Manokwari, Papua. Reinwardtia 13(2): 183-187. - Two new species of Freycinetia from Manokwari, Papua were described; Freycinetia gunungmejensis Sinaga and Freycinetia aculeata Sinaga. These two species are placed into two different groups. F. gunungmejaensis is placed in the non imbricate leaves group that has a non imbricate arrangement of leaves, caducous auricle, 1-keeled prophyll at the base of inflorescence, auxiliary or terminal inflorescence, and with cauline leaves on the terminal inflorescence/ Whereas F. aculeata is included in the imbricate leaves group that has an imbricate arrangement of leaves, persistent auricle, without prophyll, terminal inflorescence and without cauline leaves. The differences between these new species and closely related species are discussed below and their description and distributions are provided.
