Agave sp. Brirron, Journ. New York Bot. Gard., vol. 8, p. 78, 1907; vol. 11, p. 197, 1910; Discovery, vol. 1, pp. 30 
and 32, 1907. 
Acaulescent, not cespitose. Leaves somewhat grayish and at first very glaucous beneath, 
lanceolate, somewhat concave, gradually acute, 20-25 by 150-250 cm.; spine chestnut, smooth, 
rather glossy, nearly straight, conical, involutely grooved to the middle, 3 by 12 mm., decur- 
rent for about its own length; prickles 5-12 mm. apart, about 1 mm. long, straight or slightly 
recurved, narrowly triangular, not lenticular at base, the somewhat membranous at first slightly 
pink intervening margin straight. Inflorescence 9 m. high, paniculate; pedicels 15-20 mm. long. 
Flowers unknown. Capsules narrowly oblong, 20 by 55-60 mm., thick-stipitate, acumimately 
pointed; seeds 5 by 7-8 mm. Said by Dr. Britton to be bulbiferous. 
Bahamas. Watling Island; possibly also to be sought on Rum Cay and Conception Island. 
Specimens examined: Wattine Istanp. Little Lake (Britton and Millspaugh, 6155, 1907, 
the type). 
Named in commemoration of the explorers who are reputed to have sighted this island 
first in the New World; and of Dr. Britton and his associates, without whose collections the pres- 
ent study would have been impossible.

flowers congested at the ends of their branches; small thin-walled capsules, and mod euwiehy 
small seeds. Not known to be bulbiferous. Conaned to the Western Antilles.

Acaulescent, not cespitose. Leaves rather few, light green or slightly glaucous, broadly

somewhat lenticular at base and on green prominences, the intervening margin slightly concave. 
Inflorescence 4—5 m. high, the upper third or more very loosely paniculate, with few outcurved
