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 cuthbertsonii bicolor

This is another one of my Dendrobium cuthbertsonii, the same species as the orange-flowered plant I posted not long ago, but this, obviously, is an entirely different color and is in fact a bicolored cultivar.  Like other plants of the species the flowers are veyr large for the size of the plant and last six to eight months.  The plant, some of which can be seen in the photos, is less than 3 cm tall and the flowers are 4-5 cm.  Some of my plants I grow in pots but this mounted on a piece of cedar shingle.

Dendrobium cuthbertsonii

I've posted this species many times, since I grow numerous plants of it with many differently colored flowers.  This is the best orange-flowered plant I have.  The flowers do not open quite as widely as some but both size and color are good.  The plant is the usual few cm tall.

Dendrobium agathodaemonis

Dendrobium agathodaemonis is very closely related to Dendrobium cuthbertsonii and considered to be the same species by some.  To my mind, however, they are quite different, the former species having very thin growths and flowers without the dark lip markings that Dendrobium cuthbertsonii has.  This is a plant I grew from a seedling and which has rather small but very clear red flowers.  The plant is only a couple of centimeters tall and the flowers around three centimeters long.  Like its close relative, it is from New Guinea and is cool growing.

Dendrobium hellwigianum

I posted this species several weeks ago but the photos were of another plant, since I have two plants.  This is the other, not much different except that flowers have a slightly different color.  The species is from New Guinea, belong to the oxyglossum section fo the genus Dendrobium and is around 10 cm tall with 3-4 cm flowers.

Dendrobium hellwigianum

I have two different plants of Dendrobium hellwigianum, the other one of them a paler pink and with more of a bluish cast to the flowers.  The species seems easy enough to grow when given cool temperatures and high light.  In this case the plant is 10 cm tall and the individual flowers between 3 and 4 cm and usually produced in pairs at the top of the pseudobulb and between the narrow channeled leaves.  Like all the Oxyglossum Dendrobiums the flowers are very long-lasting.

Dendrobium cuthbertsonii bicolor

I grow numerous clones of this species in all different colors and sizes, but this is one of my favorites.  I like the rose-purple and the clear color differentiation, as well as the fact that the flowers open widely.  Like at Dendrobium cuthbertsonii, this is a tiny plant, only a couple of centimeters tall with huge flowers for the size of the plant, in this case 4-5 cm.

Dendrobium vexillarius

Dendrobium vexillarius is a high altitude miniature species from Papua New Guinea.  It is variable both in plant size and in flower color, producing flowers in a rainbow of colors on plants that are even smaller than this or four to five times as large.  My plant is 8cm tall.  The unusually colored flowers are 3 cm and last for many months.  They are produced at the end of the older pseudobulbs, often after the leaves have fallen off, and are usually two or three to each growth.
