Rottler. Judging from the coloured figures in Herb. Perad., we have also 

 in Ceylon S. Arachnites^ Rchb. f. — Trimen. 



S. Aradmites is a Malayan species, with larger fl. than 5. co7npla7tatus, 

 and caudately acuminate sepals and petals. Probably the figures alluded 

 to were made from imported specimens. The genus DcndrocoHa, Bl., 

 should perhaps be maintained for the species of Sarcochilus with an infl. 

 of distichous, persistent, fleshy bracts, and the lip jointed on to the base 

 or foot of the column. — J. D. H.
