Oncostele Romance 'Oro Rojo'

Oncostel Romance 'Oro Rojo'

Oncostele Wildcat was parent to Oncostele Catatante, and Oncostele Catatante is the parent to this brightly colored orchid. Oncostele Romance is a 2010 cross between Oncostele Catatante and Oncidium Petite Shine.

There's a couple different cultivars of this hybrid out in the internet. The 'Oro Rojo' I photographed has scarlet petals and a golden lip. Meanwhile, Oncostele Romance 'Peachy' has the same orange tones as its parent Oncostele Catatante.

I could not complete a genealogy for the orchid. This hybrid's parentage has something like 200 parent plants, and the software I use to draw my genealogy trees cannot handle files of this size. The complexity of the orchid's lineage comes from the utter mess of orchid breeding that went on in the first half of the 20th century. During this time, a relatively small number of primary hybrids were being bred among each other in every combination possible to produce a plethora of very closely related orchid crosses. But if you follow the genealogy trees, all of these hybrids reach back to the same handful of parent species.

The result is: Oncidium Petite Shine has over a hundred progenitors. However, it only adds 1 new oncidium species to the parentage of Oncostele Romance, that were not already represented in its other parent, Oncostele Catatante: Oncidium noezlianum.

Oncostele Catatante

Oncostele Catatante 'Pacific Sunspots'

This fiery oncidium intergenic is named Oncostele Catatante 'Pacific Sunspots.' The hybrid is an old favorite at the New York Orchid Show--I photographed two different clones of this cross, Catatante 'Kilauea Karma' and Catatante 'Alice' in 2013. The flowers from this orchid are bountiful and bright, demanding attention.

Oncostele Catatante is a 2002 cross between Oncostele Wildcat and Oncidium Sphacetante. Both of the parent orchids were familiar to me. I wrote a post on the complicated lineage of Oncostele Wildcat earlier this year. Meanwhile, Oncidium Sphacetante is an older hybrid that made up a significant contribution in the lineage of Oncidium Volcano Midnight. I would say that all of these oncidium hybrids share many similarities.

Oncostele Wildcat, Maria's Orchids: The Many Faces of Oncostele Wildcat

As I wrote in the post about it, Oncostele Wildcat comes in many different colors, depending on the clone. This makes it hard to guess which one was used in making Oncostele Catatante. Further, the differences between Catatante 'Alice' and the other two Catatante clones suggest that different Wildcat strains were used in the makings of each.

Here is the full lineage of Oncostele Catatante:

Lineage of Oncostele Catatante

I re-drew my lineage of Oncostele Wildcat to try and get the relationships between the parent plants to be more legible. However, there is probably no amount of rearranging that can fully untangle this mess. It seems that when people first figured out how to cross Oncidium orchids in the end of the 19th century, hobbyists were just breeding the crosses every which way, resulting in these incestuous loops. A great deal of hybrids from the 1940s and earlier actually descend from a relatively small pool of parent species.

The lineage contains a total of 10 Oncidium species, and 1 Rhynchostele species. Here they are in full:

New York Orchid Show 2013: Oncidiums

Aliceara Tropic Tom

Oncidium hybrids and intergenics were some of the best represented genera at the New York Orchid show this year. There were giant sprays of these blooms absolutely everywhere throughout the greenhouses. I hope you enjoy these as much as I did.
