516 GRAMINACEAE. [ Agrostis. — 
keel, the lower one little longer than the upper. Flowering glume thin, 
glabrous, 4-nerved above, truncate or faintly denticulate, awned below 
the middle, the awn only '/4 longer than the glume and ‘straight. Palea 
wanting. Ovary obovoid, the short styles rising from the angles and 
plumose from the base. s Aibesnuee ovate - acuminate. 
i 1 Th bit an 
indication probably of a pubescent floret i in some formas, “which character would ing. our 
species near A. Chamissonis, Trin., from Easter Island, A. elatior, Steud., from N. Zealand, 
and other species of the Southern Pacific. 
2. A, fallax, sp. n. — Tufted, about 1 ft. high, the stems simple, erect, 
terete, glabrous, the uppermost leaf at the base of the panicle. Leaves - 
linear, glabrous, rough at the margins, 3'/2—2‘ long, the lowest convolute, 
the upper ones plane and considerably longer than their loose sheaths. 
Ligule ovate-lanceolate. see narrow, 3‘ or more long, the rays ternate 
in the lowest nodes, about 1‘ long, appressed, Syaachint g from above the 
middle. Spikelets on scabrous pedicels of their own length or longer, 
purplish, compressed, 2“ long, the floret naked at the base. Outer glumes 
herbaceous, glabrous, ovate-lanceolate, acute, 1-nerved, with the keel 
scaberulous above, the lower glume longer than the upper. Flowering glume 
nearly !/3 shorter than the latter, thin, concave, obtuse, entire, 4-nerv 
awned from the base of the back, the awn twice as long as the glume er 
geniculate. Palea minute, shorter than the ovary. Lodicules 2, slightly 
emarginate. Ovary and s as be 
Plateau of Mt. Eeka, Maui! In appearance much like Deyeuaia Hillebrandi from the 
same locality. 
3. A, Kanaiensis, sp. ». —- Stem weak, compressed, geniculate below, 
l'/2—2 ft. long, naked above, its uppermost internode very long (8—9’) 
cee rather firm, plane, glabrous, roughish on the margins, the blade 
the uppermost 7—8’ long and 3” broad, its sheath 4—5‘ long; ligule 
ovate- lanceolate, 2. Panicle 4—5‘ long, oblong and contracted to pyra- 
idal and quite open, with rhachis and rays smooth in their lower 
portions, the rays of the lower nodes very unequal in fascicles or whorls 
of 3—5, horizontally patent at last, the longest measuring 2‘ and dividing 
from near the middle, the shorter ones from the base, into short patent 
branchlets; the pedicels shorter than their spikelets and faintly scabrous. 
Spikelets */4—1, rather pale, glabrous, awnless. Empty glumes of equ 
le , broadest at the middle, rather obtu tuse, 1-nerved, faintly scabrous at 
the sensitiighs keel. Floret half the length of the outer glumes, thin scarious, 
its glume obovate-truncate, 2—4- aap at the apex, faintly 3—5-nerved, 
the middle nerve not running into a tooth. Palea as long as its AS 
meng bidentate, broadest and itt at the middle. Anthers p
