brown basal thickening, 5-6 by 15 mm., decurrent and dorsally intruded into the green tissue; 
prickles red to chestnut, about 5 mm. apart, scarcely 1 mm. long, straight, or those below the 
middle twice as long and recurved, narrowly triangular, often from lenticular bases, the inter- 
vening reddish margin straight and often minutely denticulate. Inflorescence paniculate; 
pedicels 15-20 mm. long. Flowers golden, about 60 mm. long; ovary 30-40 mm. long, about 
one-half longer than the perianth, subfusiform; tube openly conical, 8 mm. deep; segments 
7 by 18-20 mm., about half as long as the ovary; filaments inserted nearly in the throat, 35 
mm. long, scarcely twice as long as the segments. Fruit unknown. Bulbiferous. 
Caribbees. Dominica. 
Specimens examined> Dominica. Grand Savanah (Jones, 1910, the type). 
Agave grenadina n. sp. 
Plate 21. 
Aspect of A. Karatio. Leaves deep green, at first slightly glaucous, then glossy, broadly 
lanceolate, deeply concave below when young, gradually acute or rather blunt, 25-30 by 200 
em.; spine brown or blackish, smooth, somewhat glossy, recurved-mucronate, with darkening 
stoutly conical involute basal thickening 5-8 by 15 mm., decurrent and deeply intruded into 
the green tissue dorsally; prickles about 10 mm. apart, 1-2 mm. long, little curved, triangular 
from small lenticular bases, the at first reddish intervening margin straight. Inflorescence 
8 m. high, the upper half paniculate; bracts deltoid, subimbricated, appressed. Flowers orange, 
about 60 mm. long; ovary 30 mm. long, equaling the perianth, fusiform; tube broad and 
shallow, 5 mm. deep; segments 6 by 25 mm., not as long as the ovary; filaments inserted nearly 
in the throat, 45 mm. long, nearly twice as long as the segments. Not known to bear capsules. 
Freely bulbiferous. 
Caribbees. Grenada, plentiful at only one place, a sandy dry estate near the sea (Anstead).
