Silica bodies and their systematic implications at the subfamily level in Podostemaceae

Blog Article

Abstract Podostemaceae is a family of eudicotyledonous rheophytes with unique morphology, sometimes resembling algae, lichens or bryophytes.This study evaluates the taxonomic value of VITAMIN COOLER PEACH MANGO silica-body morphology (presence, location, size, shape, ornamentation) in species representing the three subfamilies: Tristicha trifaria (Bory ex Willd.) Spreng.(Tristichoideae), Weddellina squamulosa Tul.

(Weddellinoideae) and Diamantina lombardii Novelo, C.T.Philbrick & Irgang (Podostemoideae).T.

trifaria and D.lombardii have silica bodies in stems and leaves.In contrast, W.squamulosa exhibits silica bodies only in the scale-like leaves.

The morphology of Resistance Brake these bodies is unique to each species.The results denote the taxonomic usefulness of silica characteristics and a need for a more complete study of silica bodies throughout the family.
