part : Dr. Boott considers it identical with C. vesicaria f3. alpigena 
Fries, but that species has 3 stigmas, while we find only two. 
vi. Terminal spikelet barren, solitary ( sometimes 2 in 37, 38, 39, 41, 
53, and 54). Fruit glabrous (or scabrous in 54). Stigmas 3. 
* Fertile spikelets abbreviated and erect, (in 40 and 41 longish and 
sometimes drooping ). 
■f Beak of fruit bifid. 
35. C. extensa Gooden. ( long-bracteate C.) ; sheaths very 
short (scarcely any) with extremely long narrow canaliculate 
foliaceous bracteas, fertile spikelets nearly sessile oblong, glumes 
slightly mucronate, fruit ovate ribbed with a short straight 
smooth acuminate beak bifid at the point, leaves very narrow 
canaliculate, stem smooth. E. B. t. 833. 
Marshes near the sea, rare; on the east and south of England; 
near Liverpool. Shores of the Menai Straits. Coast of Fifeshire, Ayr- 
shire, &c., Scotland. Ireland. 2). 6 About 1 foot high. Quite 
distinct from C. fiava, with which it has been confounded, in its 
very narrow canaliculate leaves, never spreading and short-beaked 
fruit. Advene oblong-elliptical, tapering at both ends, triangular and 
smooth. 
36. C. fiava L. ( yellow C.)\ barren spikelet cylindrical 
obtuse, fertile spikelets globose or oval nearly sessile, lowest 
with a nearly included stalk, glumes obtuse, bracteas long 
leafy, fruit obovate turgid ribbed spreading with a long more 
or less deflexed or straight beak bifid at the point, stem 
bluntly triangular smooth. — a. barren spikelets distinctly 
stalked, fertile ones rather distant, beak of fruit long deflexed 
distinctly rough-edged. E. B. t. 1294. — (3. spikelets all 
approximate, beak of fruit long rough-edged straight. C. flava 
(3. lepidocarpa Anderss. C. CEderi Ehrh.f: E. B. t. 1773. 
— y. spikelets somewhat approximate paler small, fruit much 
smaller suddenly attenuate into a short straight nearly smooth 
beak. C. CEderi Anderss. C. extensa j3. McLaren. 
Turfy bogs, frequent. — /8. moist sandy places or heaths. 
— y. perhaps not rare; marsh near Prestwick, Ayrshire. If. 
5, 6. — Stems 6 — 12 inches high. Bracteas very foliaceous, the 
lower one resembling the broad acuminate leaves. Spikelets, and 
indeed the whole plant, cf a yellowish hue. Achene obovate, with 
3 nearly equal flat sides and thick angles, very minutely and closely 
dotted with impressed points, at length nearly quite smooth. Our 
/8. is the C. CEderi of E. IS. (as we have now ascertained by means of an 
authentic specimen) and of most British collectors. The y. is C. 
CEderi of Andersson and the botanists of the north of Europe, and has 
much more the aspect of C. extensa, but the achene is the same as in 
C. fiava.
