Japan Red List (2000)

An epiphytic orchid that grows on trees in evergreen broad-leaved forests. Its pseudobulbs are ovoid-conical in shape. The leaves are linear-lanceolate, 2-4 in number, and 30-50cm long. The flower stalks emerge from the side of the pseudobulbs from February to April and bear 5-10 flowers sparsely. The sepals are pale yellow with dark purple-red lines along with the lateral petals. The lip is ovate, shorter than the lateral petals, blunt, and conspicuously recurved, with irregular purple lines on a pale yellow background.

The current status is unknown in 2 out of 4 mesh squares, and only a few individuals are growing in each of the remaining 2 mesh squares. The main factor causing the decline is the collection for horticultural purposes, but the impact of deforestation has also been noted in 1 mesh square.
