December blooming oncidium alliance orchids: Rodriguezia decora

[Hoa Tony Nguyen]

I start this thread with this unusual species, Rodriguezia decora - very unusual flowers for an oncidium-type orchid. It has very long spacing rhizome hence grows best with a "long" mount.
Cheers. Hoa.

They are unusual. I would love to see a photo of the whole plant, if you have it?

Rhynchostele bictoniense (i.e. Lembroglossum bictoniense or Odontoglossum bictoniense), another oncidium type orchid is currently in bloom (winter to spring). Lovely.
Cheers. Hoa.

Your Rodriguezia decora is spectacular. And that is such a great closeup!

The Burrageara (Burr) complex hybrid results from Cochlioda x Miltonia x Odontoglossum x Oncidium cross. Intriguing hybrid, seems to be tolerant of many different growing conditions.

BTW, Dear Jenn, usually I don't take picture of my plants. They don't look as exciting as the blooms. The Rodriguezia looks just like a small oncidium with very flat pseudobulbs which are separated from each other by around 5-10 cm with a rambling rhizome.

Cheers. Hoa.

Most brassia have greenish color but the flowers of this plant from the above cross turn yellow after about 1 week. Maybe that is due to the Brs. cochleata (sym. Brassia lawrenceana).
I still have to figure out how to photograph these spider orchids. The petals and sepals are so long and thin, 12 inches!

Cheers. Hoa.

Degarmoara Winter Wonderland 'White Fairy'
(Miltassia Cartagena x Odm. Gledhow)

This robust clone is very popular. I have seen it everywhere. Very easy growing plant (warm, cool, intermediate), it just grows, grows and then blooms. Love the pristine white color!

Cheers. Hoa.

Today, I post a picture of the the Onc. tigrinum currently in bloom in the greenhouse. The interesting background of this species is included below for our reading enjoyment!
Cheers. Hoa.


The type species of the Oncidium Section is Onc. tigrinum which has been described as one of the most beautiful and free blooming of the large flowered yellow oncidiums. It produces branching panicles of flowers during the dull months of autumn and winter, which greatly enhances its value, and it lasts six weeks in bloom. Its pseudobulbs are rather globular and compressed, being some 75 to 100 mm in diameter. There are two to three leaves 225 to 300 mm long, folded at the base, rather leathery in texture. The inflorescence is stout, usually erect, to 1 metre tall, loosely panieled, rather many flowered. Individual. flowers are about 75 mm long, long lasting, the sepals and petals bright yellow, more or less heavily blotched with rich brown. The lip is large, spreading, vivid yellow, sometimes with a brownish suffusion on the broad isthmus. Autumn-winter flowering, it is native of Mexico. It has been in cultivation since 1840, and is a cooler growing species. In hybridisation, this species has been used with considerable success, especially in intergeneric breeding with odontoglossums and also with oncidium species, and it is said to impart vigour, large lip size and excellent spike.
