Dendrobium agathodaemonis

Dendrobium agathodaemonis is usually considered a synonym of Dendrobium cuthbertsonii and comparing this post with the previous will certainly show why.  If there are any reason to consider them separate species then the lack of dark markings on the lip and the very thin growths distinguish this species.  The growth on my plant are 1 cm tall and produce 3 cm flowers.  My plant is grown on a piece of cedar and the flowers are pendant.

Dendrobium cuthbertsonii bicolor

This is one of a number of bicolor Dendrobium cuthbertsonii I own, and this is one of the better examples, with very large and very open flowers.  Like other examples of this species the plant itself is tiny, only 2 cm tall, with 4 cm flowers.  Some of the plants of this species I grow mounted.  This is grown in a clay pot in live sphagnum, but does no better than those that are mounted.

Dendrobium Illusion

This is one of several plants I own of the hybrid of Dendrobium cuthbertsonii and Dendrobium lawesii.  The cross has reduced the size of Dendrobium lawesii, a species with long pendant canes, and has produced a plant with erect growths and flowers that are more open (those of Dendrobium lawesii are tubular).  The hybrid has canes 12 cm tall with 3 cm flowers that are produced in clusters.  The leaves have the "pebbled" appearance of the Dendrobium cuthbertsonii parent.

Dendrobium Mountain Magic

This is a Dendrobium cuthbertsonii hybrid, a cross of that species, less than 3 cm tall, and Dendrobium pseudoglomeratum, a very large plant.  The smaller parent has reduced the plant size to around 15 cm but the flowers are still very large, 4 cm long.  The plant blooms several times a year and is more tolerant of warm temperatures than its Dendrobium cuthbertsonii parent.  My plant is grown in live sphagnum in a clay pot with cool temperatures and good humidity and light.

Dendrobium limpidum 'Ashley'

Dendrobium limpidum is from New Guinea and belongs to the Pedilonum section of Dendrobium.  This group of Dendrobiums have arching or pendant canes and most of them are quite large.  This plant is one of the smallest in the group.  It is considered by some to be the same plant as Dendrobium dichaeoides and  the plants do resemble another orchid genus named Dichaea with their closely set alternating leaves.  The canes are about 10 cm in length and produce clusters of rather small flowers that impress more by their bright color and number than by their individual beauty.  The flowers are less than 2 cm but come in clusters of around 15 flowers.  Like the other flowers in the Pedilonum section the flowers tend to be more or less tubular.  In this case the flowers are not only tubular but do not open very far and have a lip that curls up to block most of the open end of the flowers.  This can be seen in the close-up photos.  One very nice thing about this species is that the older canes continue to produce flowers for several years, though the new canes do not bloom the first year.  The older canes eventually lose their leaves but will even then continue to produce flowers.  On another note: I took this plant in for judging a few days after I posted this and it received a cultural award (Certificate of Cultural Merit) from the American Orchid Society.

Dendrobium seranicum 'Brendan'

This is my awarded plant of the species.  Dendrobium seranicum is from the island of Seram in the Moluccas, loves cool temperatures and high light, has very long lasting flowers on a miniature plant, and is one of the Oxyglossum Dendrobiums.  The plant is 8 cm tall and the flowers are 3 cm, usually produced in pairs from the top of the pseudobulbs and between the two or three succulent leaves.

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.

Dendrobium petiolatum

Dendrobium petiolatum is another species from the Oxyglossum section of that genus, one of my favorite groups of orchids.  It is one of the larger species in that section, though still small, and the flowers have all the characteristics of that section.  They are colorful, with a lip that is differently colored and accents the flowers beautifully.  The plant with its round pseudobulbs is 9 cm tall and the flowers, which come in clusters from the top of the older leafless pseudobulbs, are 2 cm.  The species is from New Guinea and this is the first time I've grown and bloomed it.
