On wet ditch-bants, in low meadows, drains and other watery and boggy places ; 

 frequent. FL3u\y — November. 0. (according to Hooker If). 



E. Med. — In a ditch near Ninham farm, by Ryde. Pientilul about Lake com-

W. Med. — In a boggy meadow a little above Newbridge towards Calbourne 

 mill, sparingly, 1844. Marsh at Easton, Mr. Snooke (perhaps S. Savii). 



Root fibrous. Stems forming tufts from 3 to 6 or 8 inches long, spreading in 

 all directions, very slender, partly barren and partly floriferous. Leaves 2 or 3 at 

 the base of each culm, channelled, sheathing the flower-stems, which they closely 

 resemble, and, like them, are setaceous and quite smooth. Spikelets ovate, 

 pointed, 1 — 3, on very short pedicels* or even quite sessile, overtopped by a con- 

 tinuation of the stem, greatly exceeding the same part in S. Savii. Glumes 

 broadly ovate, whitish and membranous, with a green blunt keel. Fruit covered 

 with a thin chaffy tunic, turbinate, dark brown, beautifully sculptured longitudi- 

 nally by prominent ribs, united by minute transverse lines or furrows. 



4. S. Savii, S. et M. Savi's Cluh-rusli. " Stem round leafy 

 below, spikelets 1 — 3 terminal shorter than the unequally 3-leaved 

 involucre, fruit subglobose minutely dotted not furrowed."' — Br.

In similar places with the preceding, and by much the more frequent of the 

 two. Fl. July — October. Fr. August — November. (or If, Hooker). 



E. Med. — Most profusely under the bank of slipped land under the cliff in San- 

 down bay, within half a mile of Shanklin chine, 1844, and where some of the 

 tufts measured as much as 15 inches in diameter. On the farthest end of St. 

 Helens green. Wet spot on Briddlesford heath, 1843. In various places 

 between Niton and Blackgang, especially along the little stream that descends to 

 the sea, in great abundance, as also in most plashy spots on that part of the coast. 

 At Knowle, near Niton, Wm. Borrer, Esq. 



W. Merf.— Colwell heath. 



(3. In a marshy meadow not far from Landguard farm, near Shanklin, plenti- 

 fully in one spot, in 1838. [At Lane end, Bembridge, — also along the stream 

 above Brixton, A. G. More, Esq., Edrs.] 



Root perennial, of many whitish creeping fibres. Stems numerous, 2 — 6 inches 

 high, obtusely angular, finely striated and dotted, very smooth, each enclosed at 

 the base in a tight sheath, often reddish below, sometimes elongated at the sum- 

 mit so as to resemble barren scapes, but which in this genus are viewed as leaves. 

 Heads of flowers terminal, of from 1 to 3 spikelets (solitary in (3.), each head sub- 

 tended by a bractea or involure of 2 unequal leaves, the uppermost longer than 

 the spikelets in a., but in /3. shorter than the mature florets. Glumes concave or 



* I have seen it in Dorsetshire with spikelets very considerably pedunculate.
