Estudios micromorfológicos y anatómicos en el género neotropical Axonopus (Poaceae: Paniceae). I. Epidermis foliar
Micromorphological and anatomical features ofthe leaf epidermis were investigated in the genus Axonopus P. Beauv. using scanning electron microscopy (SEM). Fourty species, which included representantive of all infrageneric categories of Axonopus, were studied. The presence and type of bicellular microhairs, unicellular macrohairs, silica bodies, prickles and hooks, and form of epidermic cells and stomata were investigated. The bicellular microhairs are of panicoid type; the macrohairs are unicellular with papillate bases; four types ofsilica bodies and 3 types of subsidiary cells were observed. Axonopus shows a panicoid dermotype. However, the leaf epidermis cannot be considered useful in infrageneric categories recognition with in the genus Axonopus. It appears that there is no clearcut delimitation among the sections and series ofthe genus Axonopus, in terms of leaf epidermal features.
