32 BRITTON: STUDIES OF WEST INDIAN PLANTS 
crowded; bracts very broadly cuneate, fully 1.5 mm. long, short- 
hairy at and near the apex; sepals of the staminate flowers 
concave, cuneate to obovate, about 1.5 mm. long, exceeding the 
corolla, pubescent at the apex; corolla-lobes minute, ovate to 
oblong-ovate, obtuse; anthers about 0.25 mm. long; sepals of the 
pistillate flowers about 1.5 mm. long, boat-like, keeled, pubescent 
near the top; petals oblong to oblong-spatulate, fully 1 mm. long; 
capsule reniform-didymous, fully 0.5 mm. wide: seeds oval, barely 
0.5 mm. long. 
White sand, vicinity of Los Indios (Britton & Wilson 14179). 
This plant is related to Eriocaulon sigmoideum C. Wright. It 
differs from it in the larger size, the more compact heads, the more 
copiously pale-pubescent and longer bracts, the smaller staminate 
flowers, and the sepals of the pistillate flowers which are wider 
below the middle, instead of at the top. 
Eriocaulon fusiforme Britton & Small, sp. nov. 
Plants 3-6.5 cm. tall, the scapes tufted, usually densely so; 
‘leaves ascending or recurved, subulate-lanceolate, 1-2.5 cm. long, 
thinnish, concave, glabrous; scapes relatively slender, spirally 
twisted, prominently 5-angled, each subtended by an obliquely 
opened sheath which is shorter than the longer leaves; heads 
dense, fusiform, becoming 7—-8.5 mm. long, acute, glabrous, brown- 
ish; bracts of the involucre ovate to oblong, obtuse, chartaceous, 
2-3 mm. long; flowers numerous; bracts rhombic-ovate or rhom- 
bic-cuneate, mostly 2 mm. long, acute or short-acuminate, scarious, 
glabrous, or obscurely fine-pubescent; sepals of the staminate 
flowers spatulate to oblong-spatulate, about 1 mm. long, some- 
times laciniate at the apex, about equalling the corolla or exceeding 
it; corolla-lobes ovate; anthers about 0.15 mm. long; sepals of 
the pistillate flowers about 1.5 mm. long, boat-shaped, strongly 
keeled and crested above the middle, acuminate; petals linear- 
elliptic to linear-spatulate, 1.5-2 mm. long; capsule suborbicular 
or orbicular-ovoid, about 0.5 mm. wide: seeds narrowly oval, 
about 0.5 mm. long. 
Pinelands, Siguanea (Britton & Wilson 14951). 
This differs from all described Cuban species of Eriocaulon. 
Its short stiff scapes and fusiform glabrous or nearly glabrous 
heads are particularly diagnostic. 
Eriocaulon ovoideum Britton & Small, sp. nov. 
Plants 6-11 cm. tall, the scapes tufted, usually densely so; 
leaves erect or ascending, narrowly linear-lanceolate to linear-
