like three round united columns. Berries bluish-black, some- 
times inclining to olive, with three or four roundish seeds, 
(generally) surrounded by a juicy pulp. I cannot ascertain 
the berries to be three-celled, and the partitions, if they exist, 
must be pulpy externally; there are marks of three sutures, 
but I have not found the valves ever separated. Embryo very 
small, lateral, diametrically opposite to the scar of the seed. 
31. Juncus trifidus.—Rocks, East of Mael Ghyrdy, August 
21, 182'1.— Capsule not at all angular, but rounded, elliptical, 
with a furrowed beak. Filaments dilated at the base. Calya- 
leaves single-ribbed. 
32. Juncus biglumis.—Mael Greadha, &c. July 23, 1827.— 
Root fibrous, slightly creeping. Stems generally solitary, 
sometimes two from the same root, roundish, compressed, 
sometimes channelled on one side, below the shortest or lower 
bractea, and thence to the base. Leaves compressed, not 
channelled, and-tubular, with distant transverse partitions, but 
not longitudinally divided ; they are much thicker than in J. 
triglumis, and the sheathing base * not much dilated.” Outer 
bractea incurved or falcate. Capsule abrupt, wider at the top, 
with three rounded projections and intermediate furrows. 
Stem l-leaved. Flowers two, the uppermost stalked, the other 
nearly sessile. Calyx rather shorter than the capsule. Stig- 
mas longer and more slender than in J. triglumis. 
33. Jancus triglumis.—J uly 27, 1827,—( Highlands. )—Stems 
frequently two or three from the same root, perfectly round, 
not channelled on one side, as in J. biglumis, naked above, 2 
generally with two, sometimes with three, leaves near the base. 
Leaves with dilated sheaths, which are auricled at the top; 
setaceous, channelled, bitubular, with transverse partitions. 
Radical leaves also setaceous, more slender and longer than 
in J. biglumis. Sometimes four flowers are found together, the 
additional one placed lower down and separated from the rest. 
Outer bractea sometimes as large as in J. biglumis ; each flower 
has one bractea at its base. Calyx-leaves more membranous 
than in the last, narrower, and more acute. Capsule longer 
than the calyz, with a tapering rather acute extremity, and 
with indistinctly furrowed sides; colour almost black.
