Bali. (Exp. R. Maier 1918, Sarip, liv. pi. cuit, in Hort. Bog. sub n. 92). 



A very interesting species of the Ascochiîus section, in tlie abscence 

 of a spur, wliich is only represented by a very short and narrow fissure, 

 it resembles 5. singulans J. J. S. from New-Guinea. The nearest, though 

 not very near, ally, however, is S. emarginatus RCHB. F. The very short 

 column foot too is very remarkable.
