ABSTRACT
A comparative study on the leaves and petioles of five Peninsular Malaysian species of Heritiera Dryand. (Sterculiaceae; was undertaken in order to investigate interspecific anatomical variations which may be useful in species identification. Characters which may be useful in differentiating certain species include the presence of hypodermis, multiple epidermis, the number of central bundles, the presence of styloids and silica bodies and the type of trichomes. A combination of these characters may be used to identify the species studied.
ABSTRAK
Anatomi daun dan petiol lima spesies Heritiera Dryand (Sterculiaceae) dari Semenanjung Malaysia telah dikaji untuk melihat variasi antara spesies dalam genus ini yang mungkin boleh digunakan untuk pengecaman spesies. Ciri-ciri yang didapati sesuai untuk membezakan sesetengah spesies ialah kehadiran hipodermis, epidermis berbilang, bilangan berkas vaskular tengah, kehadiran stiloid dan jasad silika dan jenis trikom. Gabungan antara ciri-ciri tersebut boleh digunakan untuk mengecam spesies yang dikaji.
Key words: Heritiera, Sterculiaceae, leaf anatomy, petiole anatomy, trichomes, crystals
