The tapering summit of the capsule, dilated sheaths, and 
doubly tubular setaceous channelled leaves, abundantly dis- 
tinguish the two flowered varieties of J. triglumis from J. 
biglumis. 
34. Juncus castaneus.—Mael Greadha, &c. July 23, 1827.— 
Hoot slightly creeping, with short runners or lateral shoots. 
Stem hollow, round, leafy. Leaves hollow, channelled above, 
rounded at the back, the channelled side very thin and almost 
membranous; within are found distant transverse partitions ; 
upper part of the leaf rounded and compressed. Heads of 
flowers often solitary. Calyx-leaves elliptic-Ianceolate, acute, 
and, as mentioned in Engl. FL, 3-ribbed. Style breaking 
off at a joint. Capsule shining, and, as well as the calyx and 
interior bracteas, of a deep chocolate colour, obscurely tri- 
angular, the angles blunt, and the sides convex, almost round, 
nearly twice as long as the calyx. The seeds are obliquely 
attached to the edge of the partition. v. Engl. Fl. 
35. Juncus obtusiflorus.—Near Bangor, July 29, 1826.— 
Stems certainly compressed, and the /eaves slightly so, some- 
times with only one leaf, generally two-leaved. Capsule ovate, 
not thickened upwards, often longer than the calyz, not always. 
The three calyz-leaves opposite to the sides of the capsule, flat, 
more acute, and less membranous in the margin than the rest. 
Panicle sometimes less subdivided, with twelve or more flowers 
in each head. The panicles of neighbouring plants are fre- 
eas so entangled together, that it is difficult to separate 
them. y 
This species is frequent in Anglesea; it grows in Cheshire, 
but is rare in that county. 
36. Luciola spicata.—Ben Lawers, August 17, 1820— 
Radical Zeaves with concave sides, rounded at the back, those 
s the stem nearly plane. Filaments dilated at the base, very. 
Short. 
37. Tofieldia palustris.—Scotland, July 20, 1827. 
Grn, Cuar, The “ calyx” appears to be only a trifid - 
tea, and, if the flower be considered en ^ = 
separated by a stalk from this supposed calyx.
