Flower Size to about 2" [3 to 6 cm]

Found in Myanmar, Thailand and Laos in primary and secondary evergreen broad-leaved and coniferous dry open forests and woodlands, commonly on sandstone along streams and rivers at elevations of 200 to 1500 meters as a miniature sized, warm to cool growing epiphytic or lithophytic orchid that has suberect, reclining to creeping, hairy, succulent-like pseudobulbs and 2 to 6, ovate-lanceolate, alternate, semi-deciduous leaves that bloom in the spring and summer with fragrant [lemony], 1 to several flowers on a short inflorescence that arises from the upper nodes of the leafed and leafless canes.

This plant does better potted than mounted and needs lower light levels in the wet summer and higher light levels in the dry winter. Keep humidity high year round.
