Culm, grass, Graminae, leaf blade, light microscopy, taxonomy


The structure of the epidermis, and the anatomy of leaves and culms, as seen in transverse sections, were studied in 10 species representing five genera of the subtribe Ischaeminae in Thailand. A number of characters, such as the leaf blade outline, ribs and furrows on both surfaces, bulliform cells, midribs and keels, number of vascular bundles in the keels, shape of sclerenchyma at blade margins, intercostal long cells, intercostal short cells, papillae, prickles, macro-hairs, silica bodies, costal short cells, culm outline and central cavity in ground tissue of culm, are regarded as particularly distinct characters among the studied species and genera. It seems likely that vegetative anatomical characters are taxonomically useful in classification of the genera (at the generic level) of these grass groups.
