NEW MORPHOLOGICAL CHARACTERS ON THE FLORETS OF SOME INULA SPECIES (ASTERACEAE)

摘要

This paper gives new information about the presence of glandular and non-glandular trichomes of the florets on eight Inula species. The trichomes are the following: glandular,capitate, biseriate trichome with a bigger subcuticular space and also with a smaller subcuticular space; glandular, reticulate trichomes; non-glandular trichomes. The different between the species might comes from their different ecological and/or life strategy but to proof it needs further investigation.
