Morphology of floral papillae in Maxillaria Ruiz & Pav. (Orchidaceae).

ABSTRACT:

Background and aims

The labellar papillae and trichomes of Maxillaria Ruiz & Pav. show great diversity. Although papillae also occur upon other parts of the flower (e.g. column and anther cap), these have not yet been studied. Labellar trichomes of Maxillaria are useful in taxonomy, but hitherto the taxonomic value of floral papillae has not been assessed. The aim of this paper is to describe the range of floral papillae found in Maxillaria and to determine whether papillae are useful as taxonomic characters.

Methods

Light microscopy, histochemistry, low-vacuum scanning and transmission electron microscopy.

Key results

A total of 75 taxa were studied. Conical papillae with rounded or pointed tips were the most common. The column and anther cap usually bear conical, ob
