Fries. — St. mostly procumbent. FI. larger than those of the 
List, in small terminal panicles the branches of which become 
much elongated as the fruit advances to maturity. — /3. holo-

pubescent. St. 6d. 9. — In fields. /3. Red Ileugh, Gateshead.

tt Caps, nearly straight, pet. mostly shorter than the calyx. 
3. C. semidecandrum (L.) ; 1. broadly ovate, sep. lanceolate 
broadhj membranous at their margins and apices, bracts with 
their upper half membranous, caps, cylindrical slightly inflated 
erect longer than the calyx, fruitstalks longer than the calyx at 
first reflexed afterwards erect. — E. B. 1630. R. 4968. — St. erect 
or decumbent, downy, sometimes viscid. Distinguished by its 
half membranous bracts. — Common in dry places. A. IV. V. 
4. C. atrovirens (Bab.); 1. ovate or oblong slightly pointed, 
sep. lanceolate acute with their apex and margins narrowly mem- 
branous, bracts herbaceous with a very narrow membranous 
margin, caps, longer than the calyx, fruitstalks longer than 
the calyx erect or ascending. — Bab. in Mag. Zool. Bot. ii. t. 9. 
C. tetrandrum Sm. not Curt. Sag. cerastoides E. B. 166. ? — Pet. 
scarcely shorter than the calyx or half as long. Fruitstalks twice, 
or 3 — 4 times, as long as the calyx, sometimes ihvaricated. St. 
repeatedly forked, bearing a flower in each fork. The mem- 
branous margin of the bracts is sometimes scarcely distinguish- 
able even in the living plant. Nearly allied to C. obscurum 
Chaub. {FI. Agen.), but French specimens of that plant have 
the fruitstalks mostly bent just under the calyx, which is not the 
case in our much more branched plant. C. tetrandrum (Koch)

near the sea. A. V. — VII. 
5. C. pumilum (Curt.) ; 1. ovate-lanceolate, sep. lanceolate 
acute with the apex and margins narrowly membranous, bracts 
herbaceous with an extremely narrow membranous margin, caps, 
slightly curved upwards longer than the calyx, fruitstalks scarcely 
longer than the calyx reflexed. — Curt. Lond. ii. 92. — St. branched 
at the root, afterwards nearly simple, prostrate, or ascending. 
FI. in small terminal dichotomous corymbs. Distinguished by its 
reflexed fruit, short fruitstalks and membranous apex of the se- 
pals. It is possible that this and the preceding and C. obscurum 
(Chaub.) may prove to be forms of one species, but I am not yet 
convinced that such is the fact. Their difference from C. semi-
