Agave Underwoodii n. sp. 
Plates B and 67 to 71.

Agave sp. Brirron, Journ. New York Bot. Gard., vol. 10, p. 104, 1909. 
Acaulescent, not cespitose. Leaves green, more or less narrowly lanceolate, gradually or 
in the broader forms acuminately pointed, concave, 20-25 by 100-200 cm.; spine brown, 
smooth or a little roughened, rather dull, straight or slightly upcurved, triquetrously conical or 
somewhat awl-shaped, openly grooved to or beyond the middle or involute, 4-6 by 15-25 mm., 
decurrent and somewhat dorsally intruded into the green tissue; prickles brown or chestnut, 
about 10 (or even 20-30) mm. apart, 2-5 mm. long, straight or somewhat curved or occasionally 
hooked, mostly downward, rather heavily triangular from lenticular bases, exceptionally on 
green prominences, the intervening margin straight or somewhat concave. Inflorescence 4-8 
mm. high, the upper three-fourths or more broadly paniculate with acutely recurved branches; 
pedicels slender, 15-20 mm. long. Flowers golden, 50-55 mm. long; ovary 25-35 mm. long, 
rather exceeding the perianth, oblong-fusiform; tube conical, plicated, about 8 mm. deep; 
segments 5 by 15 or 20 mm., typically about half as long as the ovary; filaments inserted 
somewhat below the throat, 30-50 mm. long, two or three times as long as the segments. Cap- 
sules narrowly oblong, about 15 by 40-45 mm., stipitate and beaked; seeds 3-4 by 5-6 mm. 
Not known to be bulbiferous. 
Greater Antilles. Southeastern Cuba. 
Specimens examined: Cusa. Santiago (Pollard, Palmer, and Palmer, 266, 1902; Under- 
wood, 1699, 1903; Trelease, 2 and 3,1907, the type; Britton, 1857, 1909). Guantanamo (Brit- 
ton, 2151, 1909). Novaliches (Mazon, 4516, 1907, with capsules 20 mm. thick; Britton, 1981, 
1909, with short ovary but representative fruit). Holguin (Shafer, 1225, 1909). 
Considerable variation occurs about Santiago in the color of spine and prickles, which are 
sometimes almost black, in the openness of the spine-groove, and in the length of the perianth 
segments and the exsertion of the filaments. The Guantanamo flowers differ from one another 
as well as from those of Santiago. Though far out of the usual range, and in the region of the 
preceding, the Holguin number is apparently referable to this species.

Acaulescent, not cespitose. Leaves dark green or very slightly grayish, at length rather 
glossy, broadly lanceolate, gradually acute, concave, occasionally plicate, 20 by 250-275 cm., 
or, according to Schomburgk, 50 by 300-450 cm.; spine brown, or gray in age, smooth, somewhat 
glossy, straight or a little upcurved, somewhat triquetrously awl-shaped, round-grooved to 
about the middle or occasionally involute, 36 by 15-25 mm., decurrent and dorsally produced 
into the green tissue; prickles from brown to nearly black, mostly 10-15 mm. apart, 3-5 mm. 
long, straight, gently curved, or bent in either direction, heavily triangular, the smaller from 
often confluent lenticular bases, the intervening margin nearly straight. Inflorescence 5-7 m. 
high, the upper two-thirds oblong-paniculate with subascending branches; bracts deltoid, 
appressed, not imbricated; pedicels mostly 15 or 20 mm. long. Flowers yellow, 55 mm. 
long; ovary 30 mm. long, exceeding the perianth, oblong-fusiform; tube about 7 mm. deep;
