Eriophokum angustifolium, Roth, var. triquetrum, Fries, in 
‘ Flora Scanica ’ p. 184, 1835. West Cornwall (‘ Journ. Bot.’ 1906, 
p. 279). — F. Hamilton Davey. 
Carex Pairaei, F. Schultz, Herb. Nonnale n. 1160, and 
‘ Flora,’ p. 302, 1 868. Between Helston and Porthleven, Cornwall, 
June, 1904. 
Habit of C. muricata ; the leaves narrower, stricter, the lower 
perishing (the leaf-fibres alone remaining) before the flowering is 
over. The ovate ligule is partly adherent to the limb, the interior 
part hollowed and curved. The spike compact, sometimes inter- 
rupted at the base. The perigynia divergent large but short (3^ mm. 
by 2) abruptly contracted into a short beak. The nut nearly as 
broad as long, glume more abruptly contracted than in muricata. 
In 7 Huricata the perigynium is 5 mm. by 2 mm. and the beak 
elongated. 
In (iivulsa the perigynia are upright, not divergent, and much 
longer than broad, — G. Claridge Druce. The name C. Pairaei is 
said (‘Bull. Herb. Boiss,’ 107, 1907) to be antedated by C.echinata, 
Murr., the latter being wrongly given in ‘Lond. Cat.’ for Good- 
enough’s C. stellulata. 
Carex elata. All., var. homalocarpa. (Petermann in ‘ Flora,’ 
1844, p. 333.) As a species. ‘ Differs from the type by its flaccid 
bending culms inclining outwards, and the flaccid dark grass-green 
leaves.’ (‘Journ. Bot.’ 1906, p. 226.) Wroxham, Norfolk. — C. E. 
Salmon. 
C. riparia, Curt., var. humilis, Uechtr. Near Brewhurst Mill, 
Loxwood, Sussex, W. Smaller in all its parts than riparia ; leaves 
shorter, only 3 — 6 mm. broad, strongly greyish-green, female spike- 
lets, usually 2, more distant, 0.20 — 0.30 mm. long, but densely 
flowered, cylindrical or ovate at the base, very shortly stalked or 
almost sessile. (‘ Journ. Bot.’ 1906, p. 227.) — C. E. Salmon. 
Lithospermum officinale, L., var. pseudo-latifolium C.
