I periodically see images or text about Cattleya trianae Sangre de Toro (or trianae var. sangre de toro). These are referring to dark reddish-lavender or fuschia colored trianae. I have also seen trianae with cultivar names of ‘Sangre de Toro Dark Lip’ and I have a cross with trianae Sangre de Toro ‘Hernando Garcia’ as a parent on the label.
When I look at trianae awards, I find that Cattleya trianae ‘Sangretoro Oscarina’ was awarded a JC in 1987, apparently for “flowers very dark magenta”, a more “fimbriated lip”, and a “lip color … very pleasing dark magenta”. The flower was not large. I see no other AOS trianae awards for a color form or cultivar remotely resembling the term sangretoro.
I suspect that the ‘Sangretoro’ part of the awarded cultivar name might have evolved into a generic trianae color type, which then transitioned to a var. for some, and then finally new cultivar names were even added to this color form (‘Hernando Garcia’). I think this would be like Cattleya trianae ‘Mooreana’ (AM/AOS in 1987) evolving into trianae var. mooreana as a descriptor of other trianae with flamea coloration.
If I am correct, there are many different Cattleya trianae cultivars in circulation carrying the Sangre de Toro (or sangre de toro) color descriptors, while trianae ‘Sangre de Toro Dark Lip’ and Sangre de Toro ‘Hernando Garcia’ should be specific cultivars. I suppose someone could name a plant trianae ‘Sangre de Toro’ but I think that would create unacceptable confusion and I would be very suspicious of an error in the labeling of such a plant.
