Systematic study of anisoptera species (Dipterocarpaceae) in Sarawak
There are five species of genus Anisoptera found in Sarawak namely Anisoptera costata Korth., Anisoptera grossivenia Slooten., Anisoptera laevis Ridl., Anisoptera marginata Korth., and Anisoptera reticulata Ashton. This study was conducted to obtain details information on leaf morphology, anatomy...

| description | There are five species of genus Anisoptera found in Sarawak namely Anisoptera costata Korth., Anisoptera
grossivenia Slooten., Anisoptera laevis Ridl., Anisoptera marginata Korth., and Anisoptera reticulata
Ashton. This study was conducted to obtain details information on leaf morphology, anatomy and palynology
characters of the Anisoptera species particularly in Sarawak region. The leaf characteristic is important for
field identification while anatomy and palynology study is important as secondary data for identification. The
specimens used in this studied were obtained from Sarawak Forestry Herbarium (SAR). This study includes
morphology on leaf, fruit and flower structure, anatomy on stomata, epidermal cell, trichome and pollen
structure. The details structure of leaves and pollen anatomy were observed using Scanning Electron
Microscope (SEM) model JSM 6390LA. From observation made, Anisoptera grossivenia possessed distinct
characters on the abaxial leaf surface with scurfy texture, has small lepidotes, and yellow-orange in
appearance. The anatomy study of the species showed that the stomata were covered by scales and clustered
hair trichomes. Four types of trichomes were observed namely the scales, glandular cell, clustered hair and
peltate trichomes. Two types of stomata were observed that were the anisocytic and paracytic types. Several
shapes of pollen were observed in this study namely oval triangular obtuse convex, oval, irregular and heart
shaped. Two types of pollen wall sculptures were observed described as reticulate and scabrate. The
morphology, anatomy and palynology studies provide pertinent information for the identification of
Anisoptera species. These informations would also be useful for the conservation and other study in the
future. |
