Potinara
''Potinara'', abbreviated Pot in the horticultural trade,〔http://www.rhs.org.uk/RHSWebsite/files/87/87be8b1e-908e-4e04-9ee6-30c438354458.pdf〕 is the nothogenus comprising those intergeneric hybrids of orchids which have ''Brassavola'', ''Cattleya'', ''Laelia'' and ''Sophronitis'' as parent genera.
It can easily be imagined that a combination of all the desirable qualities of the four genera would be an outstandingly handsome thing. However, plants in which all the desired qualities show up occur in only a small proportion of the offspring, and the percentage of plants homozygous for all qualities even less often. A rather extensive breeding program would be necessary to achieve the ideal results. Many lovely combinations do occur in Potinara crosses, although relatively few have been made.
The search for a way to breed large red hybrids has been given a new boost with the discovery of ''Cattleya milleri''. It is hoped that this species will not offer the genetic difficulties that have plagued hybridists using Sophronitis. Some encouraging results have already been achieved. (''C. milleri'' is one of the grandparents of the pictured Brassocattleya Hoku Gem.〔Registration of Brassocattleya Hoku Gem as ''Cattleya'' Tangerine Jewel × Brassocattleya Richard Mueller http://apps.rhs.org.uk/horticulturaldatabase/orchidregister/orchiddetails.asp?ID=78222〕〔Registration of Brassocattleya Richard Mueller as ''Brassavola nodosa'' × ''Cattleya milleri'' http://apps.rhs.org.uk/horticulturaldatabase/orchidregister/orchiddetails.asp?ID=60888〕)
==History==
In 2008, the genus ''Sophronitis'' was merged into ''Cattleya'', making such nothogenera as Potinara, Sophrolaeliocattleya and Sophrocattleya no longer current, but only of historical interest. At the same time, several species of ''Cattleya'' which had been widely used in hybridization were moved into the new genus ''Guarianthe''. (Two species of ''Brassavola'', ''B. digbyana'' and ''B. glauca'' had been moved into the new genus ''Rhyncholaelia'' earlier in the decade.) As a result, greges which were once classified in Potinara are now found in several genera and nothogenera.
