Orchidoideae [SEP] parent taxon
Orchidoideae
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae).
They typically contain the orchids with a single (monandrous), fertile anther which is erect and basitonic.
The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies in the natural group of the monandrous orchids because of 
- a shared terrestrial habit
- sectile (capable of being severed) or granular pollinia
- erect anthers.
The Orchidoideae contain two subclades with the following tribes
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
