 be esteemed only a form of 0. nubigena.

The Kashmir examples resemble ordinary large European typical ones. Slema 

 20 in. Leaves i— 1- in. broad, flat when dry. Infl. 2-3 in. by i in., consisting of 

 4-8 globose spikes, lower shortly distant. Anthers with a linear crest. Vtricle 

 large, i in. long, yellowish, with a few irregular nerves on convex face, otherwise 

 nearly nerveless, beak bifid i its length, margins closely minutely scabrid or nearly 

 smooth. Suti utricle, subquadrate-ovoid compressed, not at all trigonous. — The form 

 C. divulsa is in infl. and general aspect nearer the subjoined var.

 Linn. The Indian var. foliosa has the crested anthers and flat leaves of muricata, 

 and is thus easily distinguished from nubigena even when young. Some of the 

 Indian plants referred here are hardly separable from the American C. stipata, Muhl. 

 which extends to Japan and Amurland. 



8. C, Thomsoni, Boott Oarex, i. 1, t. 1 ; stem lignescent with many 

 nodes, spikes ellipsoid androgynous male at top forming a close linear 

 compound spike long overtopped by leaves, style 2fid, utricle ovoid- 

 triangular thinly obscurely many-nerved with numerous red glands 

 thronghout. Boeck. in Linnsea, xxxix. 93. 



Himalaya and Khasia, alt. 1-5000 ft., from Kumaon, Thomson, to Uppeb 

 Burma, Griffith, frequent, only on river margins. — Distbib. Tonkin. 



Stems 1 ft., densely casspitose, very rigid, black in age, and often shining, 

 perennial, not rarely rooting at top and throwing thence a cluster of stems the next 

 season. Leaves numerous, infolded when dry, narrow, far overtopping tlie infl. 

 Znfl,. often by 4-5 by J in., dense, of 25-30 regularly placed brownish spikes. 

 Utricle small, brownish, plano-convex, hardly narrowed into the triangular shortly- 

 notched beak. — The younger examples have been mixed with 0. nubigena, Don, 

 which has the infl. sometimes dense and regular j but in 0. nubigena the infl. is less 

 overtopped by leaves, and the utriele is more narrowed into the beak.

 equalling the green stem, spikes ellipsoid androgynous male at top 

 numerous forming a close linear compound spike, style 2-fid, utricle ovoid
