The pollination mechanism in Trigonidium obtusum Lindl (Orchidaceae: Maxillariinae): sexual mimicry and trap-flowers.
The pollination process in Trigonidium obtusum Lindl. (Epidendroideae: Maxillariinae) is documented. The flowers are pollinated by sexually excited drones of Plebeia droryana (Meliponinae). When attempting to copulate either with sepals or petals, these bees slip on the waxy perianth surface and become trapped in the funnel-like flower tube. Bees trying to escape from the flowers may instead ac...
متن کاملCryptocentrum beckendorfii (Orchidaceae: Maxillariinae), an extraordinary newspecies from Andean Peru
Cryptocentrum beckendorfii is described and illustrated from a single cultivated plant reputedly from the Amazonian slopes in the Cuzco region of Andean Peru. This species is similar to C. pseudobulbosum, also from the Amazonian slopes of the Andes, with which it shares sympodial habit with pseudobulbs unlike most species of the genus, which are monopodial and lack pseudobulbs. It differs from ...
متن کاملPseudopollen in Eria Lindl. section Mycaranthes Rchb.f. (Orchidaceae).
BACKGROUND AND AIMS Pseudopollen is a whitish, mealy material produced upon the labella of a number of orchid species as labellar hairs either become detached or fragment. Since individual hair cells are rich in protein and starch, it has long been speculated that pseudopollen functions as a reward for visiting insects. Although some 90 years have passed since Beck first described pseudopollen ...
متن کاملLabellar micromorphology of Bifrenariinae Dressler (Orchidaceae).
BACKGROUND AND AIMS The two closely related subtribes Bifrenariinae Dressler and Maxillariinae Benth. are easily distinguished on morphological grounds. Recently, however, molecular techniques have supported the inclusion of Bifrenariinae within a more broadly defined Maxillariinae. The present paper describes the diverse labellar micromorphology found amongst representatives of Bifrenariinae (...
متن کاملRe-Establishment of the Genus Ania Lindl. (Orchidaceae)
Ania Lindl. is a small genus of the tribe Collabieae subtribe Collabiinae (Orchidaceae). For the last 150 years, it has generally been treated as a synonym of Tainia Blume. In this study, we critically re-examined morphological characters that have been used to distinguish Ania from Tainia, and assessed the phylogeny of Tainia using morphological and palynological characters. Sequences of the n...
