468 CYPERACEAE. [Cyperus. 
Only one specimen, collected on Maui or Molokai! Stands near C. strigosus, yet 
is suffictently distinguished by the fewer subumbellaie, beeen’ spicate and Poe gyr 
obtuse branches, the inappendiculate ochreae and the obtuse muticous glumes. The 
branches have the bottle-brush appearance of many Mariscus. 
12. C. hypochlorus, sp. n. — Stem 2—3 ft. high, sharply trigonal, 
smooth. Leaves as long or longer, 6“ or more broad, wrarene nerved or 
channelled , bie! scabrous on edges and under side. Umbel compound, 
large, 8—10-rayed, o , the ifs ss ading rays 3—6‘ long, wih “guage 
truncate ‘Siligee ites te low, the Jarger ones emitting at nearly the same 
height 2—4 short saree debreothts: finally resupinate branches (the 
lowest 1—1'/2’ long), besides the longer terminal one, all spicate in their 
entire length. Largest involucral leaves several times the length of the um- 
bel. Leaves of involucel linear or filiform, equalling the lateral branches. 
Spi OR horizontal or res oa supported by a persistent lanceolate 
or subulate saastbe le of 3—1” in length, linear-lanceolate, 6—8” long, 
compressed, acute, green. dncuite 6—8, stiff coriaceous, Seisbis lanceolate, 
3’ long, acute, shortly mucronate at the apex, carinate, 13—19-nerved, 
ith nerves stout and prominent, the thick 5-nerved keel green, the 
sides whitish. Rhachis articulate above the empty glumes, pale green, with 
thick whitish wings extending the whole length of the deep foveola. 
Stamens 3, with yellow anthers. Style 3-fid. Achene ovoid or oblong, 
laterally compressed, asides disk brown, smooth and shining, almost 
ied in the narrow and deep foveola, less than half the length of the

Stem 2—4 ft. long, rather slender, gee’ trigonal or somewhat pss 
smooth. Leaves mostly shorter, 4—6 broad below, scabrous on edges 
and both faces. Umbel open aga an compound, many-rayed, the rays 
compressed , with long bidentate ochreae, of very unequal length, and 
, some reaching 4—5’ and others only 1’ in length, sending 
out near the apex a short contracted raceme or cluster of short branches, 
the lowest horizontal and not exceeding 1‘, most of them more or less 
naked at the base and densely spicate beyond, forming thick epee 
ovoid or short and obtuse, cylindrical spikes, none longer t 
Four or five involucral ages longer than the umbel. Bracteal ols e 
branches filiform and shorter than these. Spikelets suberect, the lowest 
at length patent, with a filiform deciduous bractlet, lanceolate, 3—4” long, 
compressed with gaping glumes, reddish-brown, 2—4-flo wered. Glumes
