These Carices were sent to A. B. Lambert, Esq. VPLS. by 

 Dr. Wallich ; they bear a greater resemblance to the European

 has taken for his model the Bishop of Carlisle's Monograph of 

 the British species, in vol. xi. of the Linnean Transactions ; their 

 specific characters are as follows :

 glumis ovatis acuminatis, culmo striato nudo inferne tereti, foliis 

 involutis. — 2. C. foliosa, digyna ; spica elongata, spiculis
