Genera or species names that are synonyms of current names are denoted with a ~.

The basiosynonym of a species is denoted with a "*". The basiosynonym is the very first name that a species had before it was changed to the current species name. If you have a name in parenthesis preceding another name, the name in parentheses is the basiosynonym. An example: ~*Ophrys bicolor Naegeli - See Ophrys apifera var. bicolor (Naegeli) Nelson: Ophyrs bicolor is the basiosynonym and in the current name the parentheses, (Naegeli), is the author of the basiosynonym, while Nelson is the author of the current species Ophyrs apifera var. bicolor.

If a genus is complete [all of the species are represented] it is preceded by a `
! denotes the Type Species of the genus
* denotes the basionym or original name with the same species taxon
I have decided to include synonyms in the alphabetical listings because I have found it frustrating to find that some growers do not stay currrent in their plant names and as such we the consumer end up buying a plant that we feel is an exotic different species only to find that it is a plant that we have had for years under the correct name. An example, Brassavola rhopalorrhachis Rchb.f is actually the common species Brassavola nodosa [L]Lindley.

Ornithocephalus Hooker 1824 SUBFAMILY Epidendroideae, TRIBE Cymbidieae SUBTRIBE Oncidiinae
This genus has about 55 epiphytic fan shaped species spread across the tropical Americas. Humid, shady, intermediate to warm conditions tied to tree fern or cork mounts and allowing the roots to dry between waterings will insure a happy plant. They have no pseudobulbs and the fleshy leaves are arranged in a basally rooting fan shape and has multiple, bracted infloresence that can arise more than once a year.
Common Name or Meaning refers to the columns similarity to a bird's head

Otoglossum [Schlechter]Garay & Dunsterville 1976 SUBFAMILY Epidendroideae, TRIBE Cymbidieae SUBTRIBE Oncidiinae.
A genus of nine epiphytic and occasional scrambling terrestrial species in Central and South America from Costa Rica to Peru that occur in higher very wet montane forests on trees and steep embankments at elevations of 800 to 3000 meters. They are as a whole cold growing epiphytes and are treated culturally like Odontoglossum. This genus is characterized by the ovoid pseudobulbs, spread on a climbing rhizome giving rise to thick leaves, an erect, racemose inflorescence, large undulate flowers with similar sized petals and sepals, and a three-lobed lip that is basally revolute.
Common Name or Meaning refers to the ear-like wings at the lip base
