Agave sp. Nasu, Journ. New York Bot. Gard., vol. 6, pp. 7-9, 1905. 
Habit of A. Nashii. Leaves typically white-glaucous, oblong or oblanceolate, more 
quickly acute, flatter, sometimes plicate, 6-9 by 40-60 cm.; spine often shorter and stouter; 
prickles closer, 2-3 mm. apart, more recurved and less uniform, very narrowly triangular, almost 
continuously joined by a narrow blackish border. Inflorescence and fruit unknown. Pedicels 
5-10 mm. long. Flowers yellow, 50 mm. long; ovary 25-30 mm. long, exceeding the perianth, 
subfusiform; tube open, 5 mm. deep; segments 5 by 15-17 mm., half as long as the ovary; fila- 
ments inserted nearly in the throat, 35 mm. long, fully twice as long as the segments. 
Bahamas. Little Inagua and Caicos islands, on dry southern exposures. 
Specimens examined: Lirrte Inacua. Moujean Harbor (Nash and Taylor, 342, 12165, 
21832; 329, 1202, 21833, Nov. 1904, the type). Sours Catcos ( Wilson, 7684, 1907). 
SISALANAE. 
Plates 106 to 115. 
Medium-sized or large suckering subacaulescent or caulescent plants with rather numerous 
firm and rigid straight narrow gray or somewhat glaucous dull smooth leaves with openly 
grooved not decurrent spine and rather small subdistant prickles (rarely all but lacking); ample 
oblong panicles; medium-sized or large greenish fetid not congested flowers with maroon-dotted 
filaments and style, abundant inflorescence bulbils; and, when produced, moderately large cap- 
sules and large seeds. 
Continental plants introduced into a few islands. 
Spine tortuous, flat-topped; prickles very slender from deltoid bases.........................--- A. angustifolia. 
Spine slightly arcuate, grooved toward the base; prickles (if present) gradually tapered.

Subacaulescent or the trunk at length over 1 m. high, cespitose. Leaves light gray-green, 
narrowly lanceolate, flatly concave, 8 by 40-65 cm.; spine red-brown becoming gray, slightly 
granular, rather dull, acicularly conical, often flexuous, the upper surface obliquely flattened, 
4 by 25-40 mm., not decurrent; prickles similarly colored or nearly black, usually 20-25 mm. 
apart, 3-5 mm. long, mostly upcurved above and recurved below or doubly flexed, very slender- 
cusped from deltoid bases, the intervening margin straight. Inflorescence 2—5 m. high, the upper 
quarter openly ovoid-paniculate with outcurved branches; bracts narrow; pedicels scarcely 5 
mm.long. Flowers yellowish green, 40-50 mm. long; ovary 15-20 mm. long, shorter than. the 
perianth, broadly fusiform; tube openly conical, about 10 mm. deep; segments 4 by 15 mm., 
about equaling the ovary; filaments inserted about the upper third of the tube, 30 mm. long, 
twice as long as the segments. Capsules subglobose or turbinate, 25-30 by 30-35 mm., stipitate 
and beaked; seeds 7-8 by 8-10 mm., broad-winged. Freely bulbiferous. 
Barbados, common as a hedge-plant and somewhat escaped; also apparently on St. Vin- 
cent. Like Yucca aloifolia, known as ‘Spanish needle.’”’ Introduced, from an unrecorded source. 
Long known in European gardens under various names and extensively naturalized in the drier 
parts of India. 
Specimens examined: Barpavos ( Waby, 107, 1895; Trelease, 21-23, 1907).
