Timing for pollen collection

For the sake of disseminating information, I wanted to share my findings after doing some more digging into my big ideas of crossing Tolumnias and Oncidiums: the following is an excerpt from a document amongst others dated 2022 created by Karl Varian that were made available through the Greater North Texas Orchid Society. Here’s the linkhttp://gntos.org/files/djc/Submitted...y_Tolumnia.pdf

The excerpt begins on the bottom of page 7 and reads:

“Tolumnia intergeneric breeding was best summed up by W. W. G. Moir:

“But nowhere in orchid breeding is there as much wasted effort as in trying to cross the species and hybrids of the Variegata[Tolumnia] into other Oncidium or intergenerics of the Oncidiinae. If they do cross, they lose their Variegata identity entirely since they are completely dominated by the characteristics of the other plant.“

One might say that Rodrumnia is the exception, but I would counter that it took 35 years and four generations of breeding with Tolumnia to obtain a hybrid that was widely used. With Rodriguezia five to six generations removed, it is almost safe to say that these are Tolumnia hybrids.”

I’m glad I can avoid a wild goose chase, but I’m still going make the crosses for fun

Edited to include that the Moirs released a book specifically about breeding Tolumnia in 1980 titled “Breeding Variegata Oncidiums” as well as “Creating Oncidiinae Intergenerics” in 1982.
