For anyone who's interested, "Stlma" stands for Stellamizutaara. This genus is a combination of B. nodosa x Ctna Keith Roth (C bicolor x Broughtonia sanguinea). The genus was named after Stella Mizuta, co-owner of Richella Orchids in Honolulu (Stella and Richard Mizuta = Richella). Richella Orchids ceased operations in the 1990's
It is one of my favorites not only because it is so easy to bloom but every new growth produces flowers. They can be in bloom almost every month of the year.
