Fourcroya gigantea BotpineH, Fl. Dutch West Indies, vol. 1, p. 38, 1909. 
Aspect of A. Karatto. Leaves transiently glaucous or slightly gray, at length somewhat 
glossy green, lanceolate, gradually acute, often somewhat plicate, as much as 200 cm.; spine 
with compressed-conical mostly upeurved involute base measuring 5-7 by 10-15 mm. and 
recurved apiculus 2 mm. long; prickles 5-10 mm. apart, 2 mm. long, straight or variously 
curved, triangular, lenticularly thickened at base, the intervening margin nearly straight. 
Inflorescence about 5 m. high, the upper third or more oblong-paniculate with spreading 
branches; bracts deltoid, approximated, subappressed; pedicels scarcely 10 mm. long. Flowers 
golden yellow, 45-55 mm. long; ovary about 25 mm. long, rather shorter than the perianth, 
subfusiform; tube openly conical, 7 mm. deep; segments 5 by 22 mm., nearly as long as the ovary; 
filaments inserted a little below the throat, 35 mm. long, about one-half longer than the seg- 
ments. Capsules oblong, light gray, 20 by 40 mm., stipitate and beaked; seeds 5 by 7 mm. 
Freely bulbiferous. 
Caribbees. The ‘‘karata” of St. Eustatius.

Aspect of A. Karatto. Spine conical awl-shaped, with rather recurved involute base 
measuring 4-5 by 10 mm. and tapered rather than apiculate tip about 3 mm. long; prickles 
10-15 or 20 mm. apart, 2 mm. long, triangular rather straight, lenticularly thickened at base, 
the intervening margin nearly straight. Flowers, fruit, and bulbils unknown.

Agave sp. SHAFER, Journ. New York Bot. Gard., vol. 8, p. 83, 1907. 
Acaulescent, not cespitose. Leaves slightly grayish deep green, transiently blue-glaucous, 
then rather glossy, oblong-lanceolate, somewhat valleculate above, abruptly or gradually 
acute, 15 by 175 cm.; spine conical awl-shaped, strongly recurved with heavy involutely thick- 
ened base 6 by 10-15 mm. and slender cusp; prickles slender, usually 2-3 or even 5 mm. long 
and recurved-appressed in the middle, somewhat lenticular at base. Inflorescence paniculate; 
pedicels 15-20 mm. long. Flowers yellow, 60-65 mm. long; ovary 30 mm. long, rather shorter 
than the perianth, oblong-fusiform, slightly contracted shortly above the base; tube open, 
about 8 mm. deep; segments 7 by 25 mm., nearly as long as the ovary; filaments inserted a 
little below the throat, 40-50 mm. long, nearly twice as long as the segments. Capsules broadly 
oblong, 20 by 45 mm.,stipitate and somewhat beaked; seeds about 5 by 8mm. Bulbils unknown.
