Floral, resin-secreting trichomes in Maxillaria dichroma Rolfe (Orchidaceae: Maxillariinae)

Małgorzata Stpiczyńska, Kevin L. Davies

Abstract


Resin-secreting, sunken, glandular trichomes have been described from the vegetative organs of Maxillaria and certain related taxa. However, until now, these hairs have not been recorded for Maxillaria flowers, nor have they been examined at the ultrastructural level for any part of the plant. Here for the first time, these hairs are described using LM, SEM and TEM, and their possible functions discussed.

Keywords
