|Oncidopsis Yellow Parade 'Alpine'|
I was, however, just barely able to complete the genealogy of this orchid. This orchid has 68 progenitors, resulting in a sprawling genealogy tree. However, in the mess that is typical of early 20th century orchid breeding, there are actually only 8 orchid species that have contributed to this cross. On the Miltoniopsis side of the family tree, only 2 Miltoniopsis species (M. vexillaria and M. roezli) have generated 16 progenitors.
All in all, it resulted in an intricate family tree that I encourage you guys to check it out. (the chart is much too large for the image embedded below to be legible, but it gives a scale to the breeding scheme.)
|The very complicated genealogy of Oncidopsis Yellow Parade|
One interesting observation revealed by Oncidium Yellow Parade's genealogy is how it is closely related to several of the other Oncidium hybrids I've profiled recently.
For example, Oncidium Brimstone Butterfly and Oncidium Golden Guinea are common progenitors for both Oncidopsis Yellow Parade and Oncostele Wildcat (which is itself a progenitor to several orchids I've written about. The progenitors of Brimstone Butterfly and Golden Guinea account for 34 out of the total 68 orchids that went into the breeding of Oncidopsis Yellow Parade. Essentially, Oncidopsis Yellow Parade shares about 50% of its genetics with Wildcat, Catatante and Sunkissed.
Oncidopsis Yellow Parade also contains ALL 16 of the progenitors that went into breeding Oncidium Midas.

Additionally, I have located my new record for oldest oncidium hybrid: Oncidium Wilckeanum. This hybrid was registered in 1880! O. Wilckeanum is a naturally occuring cross between Oncidium alexandre and Oncidium luteopurpureum. During the late 1800's orchid enthusiasts would attempt to replicate natural hybrids by crossing the species they suspected to be parents of a given hybrid orchid. Oncidium Wilckeanum was one of the very first hybrids to have its parentage registered and recognized (though not without continuing controversy and debate). No one seems to grow this cross anymore, however, as I could not find any images of what this hybrid may have looked like.
Finally these are all of the 8 species that were bred together to create Oncidopsis Yellow Parade: 6 species of Oncidium and 2 Miltoniopsis.
