472 CYPERACEAE. [Fimbristylis. 
1. F, Hawaiiensis, sp. n. — Stems densely tufted from a short and 
thick rhizome with black wiry rootlets, 6—9‘ high, very slender, slightly 
compressed. Leaves few, straight and erect, filiform or wiry, plano-convex, 
not broader than the stems and about half their length, almost smooth, 
green, not glaucous. Spikelets ovoid-lanceolate, acute, 3—3'/2‘’ long, either 
3 - a simple cyme, the middle one sessile, the lateral ones on pedicels 
out 4“, or 4—5 in an irregular umbel with one only sessile. Largest 
inva leaf about as long as the cyme or umbel, the others shorter. 
actlets glume-like. Glumes ovate, 1'/2’’, convex, carinate near the apex, 
1. pitty mucronate, subchartaceous, pale or greenish at the base and 
middle, dark brown or blackish at the sides above, as is also the nerve 
near the apex. Stamens 3, enclosed. Style flat, bifid, fimbriate, slightly 
swollen at the base, deciduous with the bulb. Achene very shortly stalked, 
obovate, biconvex, brown, apparently smooth but under the lens exhibiting 
longitudinal and transverse lines, without however being ae 
High plateau of Hawaii! Nearly allied to 7. schoenoides, Vahl, yet ciently distin- 
gnished by the — number of spikelets, which are neither sida nor aie and by 
the single-neryed glume. 
2. F. polymorpha, Boeckeler, in Linnaea, XX XVII, 14. — Stems tufted,

%/4—1'/2 ft. long, angular, compressed above. L numerous, about 
half as long, glaucous, thin and flat, grass-like, 1'/2“ bch not carinate, 
shortly acuminate, glabrous, serrulate on the m margins, mostly curv 
Spikelets ovoid-oblong, acute, 3!/2—4” long, brown, numerous, weet 
a shortly stalked in err at the ends of the very unequal rays of 
ose umbel; the 2 or 3 longest rays projecting to the length of

g their corresponding rays. Bracteoles of spikelets filiform. 
Glumes 11/2“, broad ly ovate, yarn almost rounded, convex- earinate 
mucronulate, with 5—7 nerves close to the ee snadiden and shining, 
pale but brownish at the sides apex and a the nerves. Stamen I.

U this species Boeckeler unites sae forty synonyms, six of them by Vahl, the most 
maeetts being: T. tipi, Vahl, F. laza, Vahl, F. communis, Kth., F. annua, R. & 8. 
Oahu! Molokai! Maui! Kaanapali. — Not reported before from this group. The 
Species is widely diffused over the tropics of both hemispheres and in a depauperate form 
(F. annua) extends to the Mediterranean regions of Europe. 
B var. longifolia. — Stem 6’. Leaves twice as long or more, straight, 
rather flaccid. Involucral leayes 3—4 times as long as their respective 
rays. Glumes navicular, pale hyaline, with two brown patches near the 
apex, the lateral nerves very faint. Style as before. Stamens 1 or 2. 
A single flowering specimen from the northern slope of Kaala, Oahu!
