10. C. strigosus, L.— Kunth, 1. c. I[, 87. — Stem 3 ft. or more high, stout, 
acutely angular, scabrous in the upper portion. Leaves as long or longer, 
5—6‘' broad, very scabrous on both faces near the end. Umbel compound, 
about 12-rayed, the rays suberect, slender, 4—7‘ long, their ochreae running 
out into a short subulate leaflet, horizontally branching in the upper third 
or fourth, the lowest 3—4 branches longest, ochreolate and approximate in 
a kind of whorl, sometimes again dividing in their upper portions, all 
ultimate branches closely spicate in their entire length and supported by 
linear scabrous bracts of ae own length or less. Involucral leaves many, 
most of them exceeding t mbel several times. Spikelets patent, each 
with a short subulate fran bracteole, linear-lanceolate, 3'/2—5” long, 
compressed, with gaping glumes, greenish. Glumes 6—8, thin, oblanceolate, 
acute, 2—-21/2 long, carinate, faintly 7—9-nerved, pale or sometimes rufous at 
the margins, with the keel darker-green and ending below the apex in a short 
and stiff erect mucro. Rhachis slender and narrow, continuous, the thin 
white margin extending along the whole length of the furrow. Stamens 3, 
included. Style deeply 3-fid, exserted. Achene(?) (half as noes as its glume, 
obtusely trigonal, with rough dots, in the American plant). — . & Arn
