Mediocalcar versteegii 'Mountainside'

I've seen this species under two names and am not sure which is correct.  I purchased it as Mediocalcar versteegii, but have also seen it under the name Mediocalcar uniflorum.  In either case it is from New Guinea and is a rambling plant, each new growth coming from the top of the previous growth.  It blooms late winter to early spring and the flowers are not long-lasting.  I have my plant in a pot, but most of it is not in the pot and doesn't need to be.
