A new and remarkable aquatic species of Schismatoglottis (Araceae) from the Philippines

Schismatoglottis prietoi P. C. Boyce, Medecilo & S. Y. Wong (Araceae: Schismatoglottideae), the first recorded aquatic species of Schismatoglottis Zoll. & Moritzi, is described and illustrated from Cebu and Luzon islands in the Philippines

Richness and distribution of reptiles and amphibians in the tropical lowland habitats of Mt. Agad-Agad, Iligan City, Southern Philippines

Knowledge of Philippine herpetofauna is progressively increasing. However, there are still areas in the country that are poorly understood and remain unexplored, particularly in the southern Philippines. Mt. Agad-Agad in Iligan City (Lanao del Norte Province) is a secondary lowland evergreen tropical rainforest in the southern portion of the northern Mindanao region, popular with the general public and a biologically important mountain ecosystem. Herein, we present the species richness and distribution of herpetofauna using standardized sampling methods. We documented 37 species of amphibians and reptiles, recording 20 Philippine-endemic species, three exotic anurans, two threatened reptiles, and one unidentified species of lizard. Species richness was higher in a mixed agricultural area (18 species, n = 108 individuals) compared to secondary growth forest (17 species, n = 86 individuals). This research provides baseline information on the herpetofauna from Mt. Agad-Agad, and additional herpetological knowledge on the distribution and ecology of amphibians and reptiles from the northern Mindanao region

A review of the taxonomy and taxonomic characters of Philippine Alocasia (Schott) G. Don (Araceae)

This study was conducted to provide insights in the taxonomy of Philippine Alocasia by investigating the morphology, anatomy and pollen characters of the component species. Results showed that morphological characters can be used to a certain extent in delimiting taxa, while leaf anatomical characters showed continuous variation between species and are not of much use for taxonomic recognition when used alone. The combined morphology, anatomy and pollen characters showed a clear distinction on the \u27heterophylla\u27, \u27longiloba\u27, \u27macrorrhizos\u27, \u27odora\u27, \u27princeps\u27 and \u27scabriuscula\u27 groups, which agree with the classification of Alocasia proposed by Hay in 1991, 1998, 1999. The distribution and ecology of the species were also reported. The center of diversity of Alocasia in the Philippine archipelago is in Luzon and the Visayan regions. All of the species, except A. macrorrhizos, are endemic to the country. This study shows that the Philippines now ranks second, next to Borneo, in terms of species diversity of Alocasia

Chemical constituents of Moringa oleifera Lam. leaves

Chemical investigation of the ethanol extract of the leaves of Moringa oleifera Lam. yielded lutein (1), β-carotene (2), phytyl fatty acid ester (3), polyprenol (4), chlorophyll a (5), β-sitosterol (6),triacylglycerols (7), fatty acids, fatty alcohols, and saturated hydrocarbons. Their structures were identified by comparison of their NMR data with those reported in the literature

Chemical constituents of Alocasia portei Schott

Chemical investigation of the dichloromethane extract of Alocasia portei afforded phytyl fatty acid esters (1), polyprenols (2), lutein (3), a mixture of stigmasterol (4) and β-sitosterol (5), chlorophyll a (6), chlorophyllide a (7), a mixture of linolenic acid (8) and saturated fatty acids (9), and hydrocarbons (10). The structures of 1-10 were identified by comparison of their NMR data with those reported in the literature
