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.  The plant is not a very eager bloomer for me, but since I reduced the light a bit it has bloomed more freely, this the best blooming yet.

Dendrobium oreodoxa x cuthbertsonii

I purchased this hybrid several years ago and as far as I know it is still unnamed.  It is a hybrid of the micro-miniature Dendrobium cuthbertsonii from section Oxyglossum and the much larger cane-type Dendrobium oreodoxa from section Calyptrochilus, both species from New Guinea.  The hybrid seems little influenced by the Dendrobium oreodoxa parent.  Both plant and flowers look like the other parent, Dendrobium cuthbertsonii.  The individual growths are less than 3 cm and the flowers are nearly 4 cm long.

Dendrobium cyancocentrum

This is another tiny species from New Guinea, but it belongs to a different section than most of the New Guinea Dendrobiums I post.  This jewel is from section Calyptrochilus.  The plant is only 4 cm tall and the flowers are 1.5 cm.  There is a blue-flowered form of this species as well, but both have the blue "column" that gives the species its name.  I am flowering this for the first time and it has only a single flower, but I thought I'd post it anyway.
