Differs from Ster. juvanica Bl. by its smaller flowers and the more 
prominent gibbosity of the lateral sepals and the lip. The tubercles at the 
base of the latter are very conspicuous. The flowers are white with 
violet spots, whilst in St. javanica they are whitish with violet tips of the 
sepals and petals. It is a very similar species. 
Klong Son, terrestrial among withered leaves. Flowers white with violet 
spots, ovary with violet elevaled lines, stem and leaves pale reddish. 
Area: The genus Stereosandra, as far we can judge for the moment, 
is confined to the islands of the indo-malayan archipelago. Stereosandra ja- 
vanica Bl. has only been found in Java.
