S70 CXLVI. CYPERACE^. 



KoNKAN : Kalyan, Wuodrow. — Distrib. India (Bengal, Assam, Bandelkaud, 

 W. Peninsula); C'liina, Japan. 



Woodrow gives Kalyan as the habitat of the plant, but I haTe seen no specimena 

 from the Bombay Presidency ; there are none in Herb. Kew. It is possible that the 

 plant collected by Wooiiruw may have been C. cori/mbosus, which is scarcely separable 

 from C. tegetiformis and which is also reported from Kalyan.
