Cirrhopetalum dentiferum (a/k/a *Bulbophyllum dentiferum)
Myrmecophilia thompsoniana (a/k/a Schomburgkia thompsoniana var minor)
Here are four interesting orchid species that range from fairly common to pretty uncommon. *Only the Cirrhopetalum has bloomed so far (it has those classic pinwheel blooms). *The Dendrobium is a famous Australian species and this one probably needs another year before blooming. *The Laelia is a rupicolous species (grows on rocks) and is a great companion for highland Neps. *Rupicolous Laelia species stay small and this one should be ready to bloom. *The Myrmecophilia is one of the ant orchids that host ant colonies in their pseudobulbs. *It's still small and, no, it doesn't have any ants. *None that I know of, anyway.
This is a pretty diverse sampler and feel free to PM if if you'd be interested in a substitution. *You can learn about each at http://www.orchidspecies.com. *Bidding will start at $12 and I'll pay for shipping when the price passes $21.
