Stems three or four feet high, (in Ireland seven or eight according to Dr. 
Wade,) erect, straight, simple, round, smooth, leafless, stiff, and very 
strong, with a sharp rigid point, turned somewhat aside by the panicle , 
and rising a little above it. Leases none, though the barren stems have 
been taken for such. Panicle compound, and repeatedly subdivided, 
from a lateral sheathing cleft, near the top of each stem, corymbose, 
many-flowered ; its branches smooth, obtusely compressed. Bractea 
resembling the point of the stem, which embraces it at the bottom, but 
smaller, and more spreading: inner ones several, still smaller, tapering, 
with membranous points. FI. partly capitate. Three inner calyx-leaves 
obtuse. Siam, broad and short. Style scarcely any. Caps, broadly 
ovate, hard, brown, sharp-pointed, with three blunt angles, and in the 
upper part as many intermediate depressions; its lower half invested 
with the withered calyx. Seeds ovate, pellucid. Tunic unilateral, elon¬ 
gated at each end.

Smaller and more slender than J. acutus , with more of a glaucous hue. 
Panicle and bractea, as well as the summit of the stem, more erect; the 
bractea much shorter in proportion, and the main branches of the panicle 
more unequal. Calyx-leaves acute, with a membranous wavy border, 
often jagged towards the point. Caps, much smaller than the last, of an 
oblong, prismatic figure, not at all ovate or rounded, and not projecting 
beyond the calyx.

and Luciola , especially of Mr. Bicheno’s observations, (Linn. Tr. v, xii.) it may be well 
to state that the original specimens of that acute investigator are deposited in the museum 
of the Linnaean Society, for future reference. E.)
