TLDR
The ultrastructure of the labellar epidermis of 13 species of Maxillaria and one hybrid was examined using low-vacuum scanning electron microscopy (SEM), and preliminary results suggest that labellar features may provide additional taxonomic characters allowing determination of intrageneric affinities.About:

Morphology of floral papillae in Maxillaria Ruiz & Pav. (Orchidaceae).
Kevin L. Davies,M. P. Turner +1 more
TL;DR: Generally, floral papillae in Maxillaria have little taxonomic value, but the absence of papillAE from members of the M. cucullata alliance, the occurrence of clavate papllae with distended apices in theM.

Lip Anatomy and its Implications for the Pollination Mechanisms of Bulbophyllum Species (Orchidaceae)
TL;DR: These findings corroborate the hypothesis that, because pollination in these species is dependent on an unpredictable external factor (wind), nectar is necessary to keep the insect in the flower for a long period.

Pseudopollen: Its Structure and Development in Maxillaria(Orchidaceae)
TL;DR: Histochemical analyses of the pseudopollen of ten species of Maxillaria section Grandiflorae revealed that the main storage product is protein, although starch is usually also present, and may indicate that this character has evolved at least twice inMaxillaria.

Journal ArticleDOI
The ecology of solitary bees
TL;DR: The development of management procedures which will permit increased utilization of native solitary bees and perhaps lead to the importation of foreign species native to the areas in which the authors' agricultural crops originated, requires a detailed knowledge of the ecology, or environmental relationships, of these bees.

Pigment distribution, light reflection and cell structure in petals
TL;DR: Petal structure and the distribution of pigments in petals were studied in relation to the functional anatomy of petals and the ways in which petals absorb and reflect light.
