Sumatra: Pariaman, Kajoe Tanam. (W. Groeneveldt, cuit, sub n. 1377).. 



This plant diff.^rs froni the other species with a compressée! distichous- 

 inflorescence knowii to me in the triangular side lobes of the lip. The 

 peduncle and rachis are much more flattened than in S. compressus Rchb. 

 F. and 5. fraterniis ]. ]. S., the leaves narrower, as are the sepals and\ 

 petals, the spur not thickened at the base, etc. S. ^/se/rtv^ws Ridl. evidently 

 belongs to the same affinity, but it has the side lobes of the lip linear 

 and acute as in S. compressus Rchb. f., the column slender with a short 

 foot, the dise of the pollinia very small. In the colour it agrées with 

 5. bipennis J. J. S. 



Description trom spécimens preserved in alcohol. 



Mr. E. Jacobson describes the colour as follows. Rachis and ovary 

 light green, sepals and petals transparently light yellowish green, lip pure 

 white dotted light purple at the base of the midlobe, column light green,. 

 foot pure white, anther yellow with a greenish yellow bar. The flowers- 

 have a very agreeable scent of ilang-ilang.
