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. 

 Ste7n 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 



Jlowers often solitary. Calyx-leaves elliptic-lanceolate, 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 bracfeas, 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 leaves slightly so, some- 

 times with only one leaf, generally two-leaved. Capsule ovate, 

 not thickened upwards, often longer than the calyx, not always. 

 The three calyx-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 Jlowers 

 in each head. The panicles of neighbouring plants are fre- 

 quently so entangled together, that it is difficult to separate 

 them. 



This species is frequent in Anglesea ; it grows in Cheshire, 

 but is rare in that county. 



36. Luciola spicata. — Ben Lawers, August IT, 1827. — 

 Radical leaves with concave sides, rounded at the back, those 

 of the stem nearly plane. Filaments dilated at the base, very 

 short. 



37. T ofieldm palustris. — Scotland, July 20, 1827. 



Gen. Char. The " calyx" appears to be only a trifid brac- 

 tea, and, if the flower be considered hexapetalous, it is 

 separated by a stalk from this supposed calyx. If the
