Taxonomic importance of epidermal characters in the IndianThespesia Corr. (Malvaceae)

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

InThespesia lampas andT. populnea, the foliar stomata are anisocytic, anomocytic and tetracytic, the first type being dominant. Further inThespesia lampas andT. populnea altogether eight trichome types are recognisable mostly on the basis of structure. The two species can be distinguished from each other by the presence of multiseriate aseptate stellate hair in the former and that of multiseriate aseptate peltate hair in the latter.T. populnea is also distinct from that ofT. lampas due to curved to wavy epidermal walls, striated surface, absence of mucilaginous cells on the leaf abaxial. The present evidence also supports treatment ofT. lampas underThespesia rather than inHibiscus.
