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 1417Q). 



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 Sf Wilson 14Q51). 



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 6-1 1 cm. tall, the scapes tufted, usually densely so; 

 leaves erect or ascending, narrowly linear-lanceolate to linear-
