22. S. IiUgardiy C. B. Clarke. Annual, glabrous. Stems tufted, 

 2 in. long, rather stout. Leaves as long as the stem, yV in. broad. In- 

 florescence a dense compound head J in. in diam., or more rarely an 

 umbel. The 1 or^2 rays up to J-J in. long ; bracts 2 in. long, spreading,, 

 similar to the leaves. Spikes \to\ in. long, very dense, compound, purple 

 and green, 1-4 in the head. Spikelets less than \ in. long, 5-8-flowered. 

 Glumes elliptic, 5-7-nerved, the green keel excurrent into a recurved 

 mucro less than J the length of the glume. Set* 0. Stamens 1 (or 2) 

 with a very small square anther. Nut narrow-oblong, trigonous, 

 smooth, brown. Style linear f the length of the nut, branches 3.

This greatly resembles Scirpus Hystrix, Thunb. ; bat the point of the glume is 

 much shorter and the nut altogether unlike. 



23. S. squarrosus, Linn. Mant. 181. A small glabrous tufted 

 annual. Stems 2-8 in. (rarely 16 in.) long. Leaves \ the length of 

 tlie stem, -j-^-^in. broad. Head of 1-6 (rarely 10) squarrose spike- 

 lets ; bracts 3-5, leaf-like, spreading or pendent, 1-2 (sometimes 4) in. 

 long. Spikelets J-J in. long, with very many flowers, greenish or 

 brownish. Glumes narrowly obovate, suddenly narrowed into a linear 

 subobtuse mucro not longer than the glume, very caducous in fruit 

 beginning from the lowest nut-bearing glume. Hypogynous bristles 0. 

 Stamen 1 or rarely 2 ; anther very small, oblong. Style scarcely any; 

 branches 3, short, much recurved. Nut § the length of the glume 

 (exclusive of the mucro), obovoid -ellipsoid, trigonous, yellow-brown or 

 ultimately black, smooth, the outermost cells minute quadrangular,. so 

 that the nut only appears reticulated under a strong magnification. —
