This species is very near C. digitatus, Roxb., and is distinguished primarily by 

 its acutely triquetrous stem ; the umbel smaller, slenderer, with usually very unequal 

 rays. The colour varies from straw-colour (at low levels) through yellow to a golden- 

 brown (at high levels) — the C atireorufus of Boeckeler ; but there is no red or 

 chestnut-x-ed in the material referred above to this species. At least, this is the 

 view of the colouration here accepted ; the copious synonymy above cited shows that 

 competent cyperoiogists have estimated the colour as of s])ecitic value.

Schweinfui-th, 2025, was the type of this variety, and should perhaps be referred

 but the spikelets are too slender for C. longus or C. rotundus, and the wings of the
