Notable Varieties:
C. trianaei also ranks with C. mossiae in having the greatest number of named clones of the Cattleya species. An inventory of the famous Dixon collection in 1930 listed 68 outstanding clones of C. trianaei and there were hundreds more in other collections and in the literature. By 1916, the Royal Horticultural Society in England had awarded 22 First Class Certificates and 24 Awards of Merit to C. trianaei, and the American Orchid Society has made C. trianaei one of its most-awarded unifoliate Cattleya species.
