Abstract

MUZAKKI, F. A., CHIKMAWATI, T. & HARTANA, A. 2020. The resurrection of Schizostachyum biflorum McClure (Bambusoideae). Reinwardtia 19(2): 93‒96. ‒‒ Based on newly collected specimens from Mount Salak referable to Schizostachyum biflorum, made it justifiable to recognize this species as different from S. iraten Steud., to which formerly it was synonymized. A complete description of S. biflorum, a comparative tabulation of the morphological features that distinguished it from S. iraten, and figures of the two species are presented.

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 (Bird's 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

The leaf epidermis and mesophyll of fifteen species of Pandanus from Java were investigated to assess the value of anatomical features in species identification and classification. Characters of diagnostic importance are epidermal cell shape, differentiation of the abaxial epidermis into costa and intercosta, adaxial anticlinal cell wall outline, occurrence of raphides in the mesophyll, distribution of cubical crystals, pallisade cell shape, papillae on epidermal cells, and the stomatal complex. Leaf epidermal anatomy was found to be useful in the identification at species level.

Abstract

Since a large number of characters are now known for Freycinetia Gaudich. and Pandanus Parkinson species, it appears useful to consider their use in identifying plants from Java. Fieldwork carried out for this study has provided stronger foundation for understanding morphological variation within the species. This study was undertaken to have a better understanding on the morphology of the family in order to make a better species delimitation. Characters of habit, stem, leaves, auricles, bracts, peduncle and pedicel, inflorescence, staminate flowers (male), pistillate flowers (female), cephalia and berries were found useful in delimitation and identification of Javanese Freycinetia, while characters of habit, stem, prop root, marginal spine, leaves, bracts, inflorescentia, peduncle, staminate flowers (male), pistillate flowers (female), cephalia, drupes were found to be useful for distinguishing among species of Javanese Pandanus.
