Rynchospora Blauneri Britton, sp. nov. 
Perennal by short rootstocks; culms filiform, weak, clustered, 
glabrous, 3-5 dm. long; leaves filiform, glabrous, shorter than 
the culms; spikelets narrowly oblong, 3 mm. long, few together 
in 2 or 3 distant compact clusters subtended by a filiform bract 
3-5 cm. long; scales ovate-oblong, acute, light brown; bristles 
none; achene obovate, light brown with darker brown margins, 
smooth, about 1 mm. long; tubercle conic, acute, about one- 
third as long as the achene. 
Sierra de Luqiullo (Blauner 247, in herbarium of Columbia 
University, collected in 1852-53). Referred by Clarke to R. 
divergens. 
Rynchospora luquillensis Britton, sp. nov. ° 
Perennial by rootstocks; culms very slender, smooth, erect, 
about 2 dm. high. Leaves narrowly linear, about 1 mm. wide, 
flat, smooth, shorter than the culm; inflorescence a small ter- 
minal cluster of few spikelets; spikelets narrowly oblong, about 
4 mm. long; scales oblong, brownish, acute; bristles about 6, 
retrorsely barbed, a little longer than the achene; style elongated; 
achene narrowly obovate, smooth, brown, about 2 mm. long; 
tubercle subulate, about as long as the achene. 
Sierra de Luquillo (Brother Hioram 364.) 
67. AN UNDESCRIBED SIPHOCAMPYLUS FROM HAYTI 
Siphocampylus pinnatisectus Gleason, sp. nov. 
and the rhachis about 2 mm. wide, with 2-4 sharp salient teeth 
or the smaller entire, sharply acute or submucronate, with a 
single midvein and faint lateral veinlets; flowers in the upper 
axils, few in number, appearing subcorymbose by the shortened 
internodes, on minutely puberulent pedicels 1 cm. long; hypan- 
hi nic, acute at base, 3 mm. high; calyx-lobes narrowly 
linear-triangular, acuminate, erect, separated by narrow acute 
sinuses; corolla red, about 25 mm. long, narrowly tubular, some- 
what curved ventrally, constricted at base, gradually enlarged 
upward, 3 mm. in diameter at the throat, its lobes all depressed, 
3-4 mm. long. ‘ 
Type, Nash and Taylor 1701, collected on an open sunny 
hillside, between La Brande and Mt. Balance, Hayti, at altitude 
of 3150 ft., August 15, 1905. 
Siphocampylus pinnatisectus differs from all other West Indian 
members of the genus in its deeply pinnatisect leaves.
