Oncidiinae
Encyclopedia
The Oncidiinae is a subtribe within the Orchidaceae
that consists of a number of genera that are closely related.
This subtribe consists of about 70 genera with over 1000 species, with Oncidium
as its largest genus. These genera consist of a single floral type based on the angle of the attachment of the lip
to the column
, reflecting pollinator
preferences. This has however led to several unreliable results and polyphyletic taxa within Oncidium
. These were transferred to Gomesa
and a new genus Nohawilliamsia
, has been described for Oncidium orthostates
Most Oncidioid species have well-developed pseudobulb
s and conduplicate leaves.
It is possible to form hybrids in some instances between multiple genera within the Oncidiinae. These hybrids are often colloquially referred to as "intergenerics."
Orchidaceae
The Orchidaceae, commonly referred to as the orchid family, is a morphologically diverse and widespread family of monocots in the order Asparagales. Along with the Asteraceae, it is one of the two largest families of flowering plants, with between 21,950 and 26,049 currently accepted species,...
