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, Eastof Mael Ghyrdy, August 

 21, 1827. — Capsule not at all angular, but rounded, elliptical, 

 with a furrowed beak. Filmnents dilated at the base. Calyx- 

 leaves sinjjle-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 

 hractea incurved or falcate. Capsule abrupt, wider at the top, 

 with three rounded projections and intermediate furrows. 

 Stem 1-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. Juncus triglumis. — July 27, 1827. — (Highlands.) — Stetns 

 frequently two or three from the same root, perfectly round, 

 not channelled on one side, as in J. biglumis, naked above, and 

 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 Jlowers are found together, the 

 additional one placed lower down and separated from the rest. 

 Outer bractea sometimes as large as in J. biglumis ; each fioiver 

 has one bractea at its base. Calyx-leaves more membranous 

 than in the last, narrower, and more acute. Capsule longer 

 than the calyx, with a tapering rather acute extremity, and 

 with indistinctly furrowed sides ; colour almost black.
