482 CYPERACEAE. [Gahnia. 
shorter than their branches or spikelets, segs long- ner clasping 
at the base. Glumes 4—6, subcoriaceous, the lowest about ?/s the length 
of the spikelet, ovate, long-acuminate, soni ae sana with scabrous 
keel; the 2 or 3 next upper ones longest, conchoid, 1-nerved (or toward 
the apex 3—5-nerved), many-lined, pale at the base, ferruginous above; 
the flowering one enclosing 1 or 2 small veces obovate apiculate scales. 
Stamens 3—5, the anthers with a conical point. Style deeply trifid, pu- 
‘bescent below, its branches undivided. Achene coriaceous, rather suberose, 
obovate- sengats, obtusely trigonal, 2—2'/2, apiculate, pale yellow or 
straw-colored, solid in its upper portion, with 2 parecer circnlar ridges 
in the cavity. — G. mucronata, Bcklr., in Linnaea, XXX VIII, 342. 
At lower elevations, from 1000 to 3000 ft. My specimens are from Hawaii and Oahu! 
Stands nearest to the Tahitian G. schoenoides, Pec and to G. Rawacensis, Kunth. 
3. G. Mannii, sp. n. — Stem, leaves and panicle as in no, 2, but the 
latter shorter, 8—10‘ long and 2-3! wide at the middle, narrowing toward 
ee and pric Saag with their bracts almost black, otherwise as 
Be 7—8, otherwise as before. Achene ondea obovate- 
ae peel piponal or compressed, tipped with the acicular base 
of the style, osseous, of a dark brick-red and glossy as in the next 
species, 2'/2—3" long, the cavity cine transverse ridges. Stamens 3. 
Achenes retained by the elongate filam

perigonial scal the re is ressio: ie 
of the achene. Except for the larger s i oo. neg of the achene (which is 
pale yellowish-brown in the Java plant) this agrees rem markably well with a 
specimen ©: a Z. & M., co apie a ‘ional in — island and in which I have

4. G. globosa, Mann, Enum. no. 526. — Stem 1—1!/2 ft. high, terete, 
ooth. Leaves two or three times as long, 4—5‘’ broad below, scarcely 
convolute, aculeolate cere margins and nerves, dark brown or black at 
the base. Infloresce contracted in a dense foliose panicle, 3—4' long 
and about 1‘ broad. cans 41/.—5", with acute bractlets of the same 
length, ae acute, subcompressed when in flower, almost black, 1-flowered. 
Glumes 8—11, subcoriaceous, all of nearly equal size, saree ges the 
Seay 5 or 6 ovate, long-acuminate, carinate, 3-nerv nerved 
toward the apex), pale at the base, dark ferruginous bore the 3 or 4 
upper ones a little shorter, conchoid, obtuse, even rounded. Perigonial 
scales 2 or 3 of about 1/s the length of the achene, pale, entire or acutely 
emarginate, connate at the base. Stamens 5 or 6, inserted inside the 
scales, with long conyolute dark brown filaments. Style trifid. Achene 3%, 
ovoid, apiculate with the persistent style, thick osseous, of a dark brick- 
red, glossy, solid in its upper portion, the pyriform cavity only exhibiting 
— transverse ridges which do not leave their impress on the seed.
