The genusAspasia (Orchidaceae: Oncidieae) consists of five species of epiphytic orchids of Central and South America. The genus is compared with closely related genera of the tribe Oncidieae.Aspasia epidendroides is found in Nicaragua, Costa Rica, and western Panama.Aspasia principissa is found in central and eastern Panama and adjacent Colombia.Aspasia psittacina is endemic to western Ecuador.Aspasia variegata is found in Colombia, Venezuela, Trinidad, Guyana, Surinam, and Brazil.Aspasia…

Subtribo Oncidiinae Benth. (Orchidaceae Juss.) no Distrito Federal, Brasil
TLDR
It is concluded that some species of Oncidiinae occurring in Distrito Federal have wide distribution while others are locally rare and require intense effort of collection for registration.
In vitro behaviour of Aspasia variegata, an epiphytic orchid from the Brazilian Cerrado
TLDR
The seedlings originated by higher chlorophyll levels during in vitro cultivation presented the highest survival rates and better development in the acclimatisation phase of A. variegata.
Population decline in the epiphytic orchid Aspasia principissa
TLDR
A possible link between low λ and a long-term decline in precipitation and recent increases in forest dynamics is discussed: variation in annual rainfall significantly affected both recruitment and growth rates of smaller orchid individuals, while the hypothesised increase in the rates of branch and tree falls would increase mortality rates in this epiphyte.

Amazonia occupies approximately 60% of Brazil and hosts one-third of the country’s orchids. Para state contains a significant portion of the Brazilian Amazon, the orchidological flora of which has

Systematics and Evolution of Seed Plants
The development of plant population biology (SOLBRIG et al., 1979) as a discipline which connects plant systematics with ecology has been one of the most important trends within recent years, though

A reconsideration of Ada and the glumaceous brassias (Orchidaceae)
TLDR
It is suggested that Ada (in the broad sense) and Mesospinidium are distinct but closely related genera.
Chromosome Numbers in Oncidium Alliance
TLDR
Somatic chromosomes were counted by the root squash in 15 genera, in which 97 species and varieties, and 40 hybrids are included, and most of the hybrids studied showed the sum of their parents' chromosome numbers though some hybrids have not.

The relationships between some orchid flowers and male euglossine bees were first observed in Darwin's time (Criiger, 1865), but the peculiarities of these interactions have been recognized only
SELECTIVE ATTRACTION OF MALE EUGLOSSINE BEES TO ORCHID FLORAL FRAGRANCES AND ITS IMPORTANCE IN LONG DISTANCE POLLEN FLOW
TLDR
Several additional compounds have been identified from orchid floral fragrances, some of which have been demonstrated in field tests to be active attractants of male euglossines, while other compounds have be shown to modify or reduce the attraction potential of various other odor components.
