entire or subspinose, no lobule. Stipules suljrotund subplane, 

 acutely decurrent at the base, to about the middle bifid, segments 

 cuspidate-acuminate, connivent, margin with few long spines or 

 entire. Flowers % on terminal branches. Jiracts adnate at their 

 base, longer than the leaves, deeply bilobed, complicate, lobes 

 obliquely lanceolate acuminate spinose or laciniate, postical half 

 the size or smaller. Bracteole oblong, almost bipartite, carinate, 

 lobes unequal, slenderly acuminate spinose. Perianth verruculose, 

 composed of a single layer of cells, about 200 round, near the 

 middle, twice as long as the leaves, projecting about half beyond 

 the bracts, pyriform or narrowly obpyramidal, deeply tricarinate, 

 flattened antically, postically ridged, angles rounded, at the base 

 terete, apex rotundate-truncate, obscurely rostellate. Pistillidia 

 slender, 1 or 2, very rarely 3 or 4. Calyptra below 2 or 3 cells 

 thick, above abruptly subglobose, delicate. Capsule globose, 

 outer la3'er ©f cells dark brown, inner pale yellow, margin of 

 valves when open reflexed, base (apex of pedicel) cruciate, hyaline. 

 Spores brown, elaters pale brown. 



]\Iale spikelets on short lateral branches ; perigonial bracts 

 about G pairs, more than twice smaller than the leaves, broadly 

 emarginate-bilobed, turgid below, lobes subacuminate, connivent, 

 lower smaller quite entire, rarely denticulate ; perigonial bracteole 

 ovate-acute, bifid to below the middle, segments subulate, margin 

 entire or unidentate ; antheridia 2, oval.
