The affinity of this plant is with C. simpler, H.B.K. Theculms are remarkably short, 
only 2 inches long at most, and winged at the angles; the radical leaves are 4 inches 
long and % inch across, broad and flat, gradually narrowing to the base, where they 
clasp the stem ; the sheathing portion has fine red veins, and the lamina has 3 prominent 
nerves, and several finer ones. "The involucral leaves are similar, and form a conspicuous 
spreading whorl ; they are from 6 to 9 in number. The осгеғе of the umbel-rays are an 
inch in length, and usually bear a distinct but small lamina. The rays of the umbel are 
weak and long, sometimes as much as 11 inches in length. As in C. simplex, the plant 
propagates itself partly by the development of bulbils in the spikelets. The specific 
name is taken from the old name of Plantago lanceolata, Linn., the leaves of which much 
resemble those of this plant.

circiter 16-floris, squamis ovatis breviter mucronatis ecarinatis striatis; stylo trifido

Cabonde ipsius Preesidii, no. 6898. Habitus Scirpi sylvatici et affinium. 
Its affinity is with C. simplex and with the preceding species; but its habit is rather 
that of C. albostriatus. Height of culm 19 inches; leaves more than one foot in length 
and 5 lines in diameter; the longest involucral bract measures 10 inches. Тһе nut is 
two thirds of the length of the glume; Ше lowest glumes іп the spikelet are usually 
more distinctly mucronate than the upper ones.
