Masdevallia decumana is a species from Ecuador only discovered in the early 1980's. It is one of the smaller species of Masdevallia and is very floriferous. My plants bloom several times a year with occasional flowers produced between times.
The species name, decumana, means "large flowered" an apt description of the size of the flowers in relations to the plant. The plant itself is only about 4 cm tall and the flowers are at least that large when measured from the tips of the tails: a very desirable species.
