Dendrobium alaticaulinum

Dendrobium alaticaulinum is a New Guinea Dendrobium from the Calyptrochilus section of that genus, though most of the New Guinea Dendrobiums I grow are from the Oxyglossum section. The Calyptrochilus Dendrobiums tend to be large plants with long semi-pendant canes, but this species is very small in comparison, the canes around 15 cm. The 2 cm flowers bloom at the end of the canes in clusters and do not open very widely.
