Mini-catts of the Cattleya Alliance

     Synopsis of Suzi Porter's program on "Mini-Catts" at 1/12/97 AAOS meeting. Mini-catts are relatively small-sized, compact growing species or interspecific or intergeneric hybrids of species that are members of the Cattleya Alliance. Hybrid mini-catts don't necessarily have to have any Cattleya species in their ancestry! Appreciation for these plants has grown substantially during the last 25 years because they're usually more easily grown and bloomed under non-greenhouse conditions than the larger, rangier species and hybrids within this alliance. They are especially well suited for hobbyist culture under lights or at windowsills and also can be put outside in summer.

     Suzi reviewed the various species, general cultural requirements, and the hybrids that have been used in producing the better-known mini-catts. Most of these bloom as small or moderate-sized plants: Cattleya aclandiae, C. forbesii, C. luteola, and Suzi's favorite, C. walkeriana (includes C. nobilior), C. intermedia var. aquinii; Laelia milleri, L. cinnabarina, L. anceps, L. pumila (various forms), L. sincorana, L. briegeri, L. lucasiana, and L. tenebrosa; Sophronitis coccinea, S. acuensis, S. brevipedunculata, S. cernua, S. wittigiana, Brassavola nodosa, B. glauca, B. digbyana; Broughtonia sanguinea, B. negrilensis; Diacrum bicornutum; and various species of Epidendrum and Encyclia. Some mini-catts produce surprising large flowers for such small plants and may bloom two or three times a year under optimum growing conditions. Some are also especially fragrant.

     Excellent slides, including many AOS award slides, showed the forms and colors of various parent species as well as the impressive and colorful variety of interspecific and intergeneric hybrids that have been produced from these plants. The greater "mix" or breadth of genetic material that many hybrids--especially the really complex intergenerics--contain also means that these tend to adapt more readily to a greater variety of growing conditions than would the parental forms. About 75 people attended Suzi's talk, and many members and guests left the January meeting with at least one new mini-catt to add to their growing collections at home.
