Lepidaploa belongs to tribe Vernonieae, one of the most complex tribes of
Asteraceae, and relationships among Lepidaploa and related genera are
poorly understood. Microcharacters may be of taxonomic value and used in
the identification of different taxonomic categories. [DM1]The morphology
of phyllaries, florets and cypselae was analysed in detail for the first
time in 23 species of Lepidaploa to evaluate the reliability of
microcharacters as taxonomic markers. The results were also discussed in
relation to closely related genera of the Vernonieae. The species were
studied using stereo, light, and scanning electron microscopy. Eight
trichome types (non–glandular and glandular) were observed on phyllaries,
florets and cypselae. This study demonstrates that the ocurrence in
different combinations of trichome types and crystals, presence of a
stylar basal node, idioblasts and glandular apical anther appendages are
taxonomically important to differentiate between related species of
Lepidaploa. However, they are of little utility to distinguish between
closely related genera of Vernonieae.
