38 MEMOIRS NATIONAL ACADEMY OF SCIENCES, VOL. XI. 
segments 5 by 15-20 mm., rather more than half as long as the ovary; filaments inserted 
nearly in the throat, 35 mm. long, about twice as long as the segments. Capsules broadly 
oblong or somewhat turbinate, 20-25 by 30-40 mm., stipitate and beaked; seeds 5-6 by 6-8 
mm. Exceptionally bulbiferous. 
Greater Antilles. The “karata”’ of St. Thomas and the Virgin Islands. 
Specimens examined: Sr. Tuomas. Krumbay, abundant in the chaparral (T’release, 16, 
1907; Hmanuel, 1908, 1909). Ma Folie, occasional and less evidently spontaneous (Trelease, 
15, 1907, the type). Elsewhere about Charlotte Amalia (Trelease, 14, 1907;, Emanuel, 1907, 
1908; Eggers, 305). Tortoua (Fishlock, 1908). Sr. Jan (Hornbeck). 
Seedlings from the Tortola plant are much darker green and glossier than the young plants 
collected on St. Thomas.

Acaulescent, not cespitose. Leaves dark green, glossy, more or less lightly glaucous 
when young, broadly lanceolate, subacuminate, somewhat plicately concave, 15-20 by 100-150 
cm.; spine chocolate or chestnut, smooth, glossy, somewhat curved, sometimes compressed 
from the sides and basally thickened, conical-awl-shaped, shallow-grooved, or involute nearly 
to the end, 2-5 or even 7 by 10-15 or 20 mm., decurrent for several times its length and dor- 
sally intruded into the green tissue; prickles mostly 15-30 mm. apart, 2-5 mm. long, straight 
or retrorsely turned, heavily triangular from lenticular bases, the intervening margin more or 
less concave. Inflorescence 5-6 m. high, narrowly oblong-paniculate in the upper half or 
more, with nearly horizontal branches; bracts deltoid, appressed, not imbricated; pedicels 
about 10 mm. long. Flowers greenish-yellow, about 55 mm. long; ovary 30-35 mm. long, 
considerably exceeding the perianth, oblong-fusiform; tube conical, about 7 mm. deep; seg- 
ments 5 by 15 mm., half as long as the ovary; filaments 40 mm. long, more than twice as long 
as the segments.! Capsules subglobose, 20-25 by 25-30 mm., stipitate, more or less beaked; 
seeds 6 by 7-9 mm. Bulbiferous, at least in western Puerto Rico. 
Greater Antilles. The ‘‘cocuiza” or ‘‘maguey”’ of southern Puerto Rico and of Culebra. 
Specimens examined: PuERTo Rico. Pefion (Goll, 626, 1899). Vicinity of Coamo Springs 
(Underwood and Griggs, 587, 1901; Dewey, 1907). Various points along the military road 
between Coamo and Aibonito, especially near the marks of kilometers 86.7, 89.2, 91.6, and 
99 from San Juan (Britton and Cowell, 1379, 1906; Trelease, 7, 1907, the type). Hills near 
Sabana Grande (Curt, 1903; Trelease, 4, 1907). Cultivated in Sabana Grande (Trelease, 5, 
1907) and at the Mayaguez Experiment Station (Henricksen, 1906; Trelease, 1907). CULEBRA 
(Britton and Wheeler, 236, 1906, with the leaf-margin notched between some of the closer nearly 
deltoid prickles, and the stout spine openly grooved to the middle). ; 
The perhaps differentiable plants of the western part of the island (pls. 79 to 82) have 
less recurving and less plicate more glaucous leaves with more triquetrous open-grooved spines 
and more often curved prickles, more ascending (young) panicle-branches, longer-pedicelled 
rather less rugose capsules, and, apparently, they more constantly produce bulbils in the old 
inflorescence. 
BAHAMANAE. 
Plates 83 to 92. 
Rather large not cespitose acaulescent plants with numerous somewhat curved fleshy 
mostly dull and gray leaves with long grooved usually papery-decurrent spine and small or 
moderate usually subdistant prickles; rather ample ovoid panicles with subhorizontal branches; 
medium-sized bright yellow flowers scarcely congested; rather large stipitate capsules, and 
medium-sized seeds. Occasionally bulbiferous. 
Confined to the Bahamas. 
1 The floral proportions are derived from enlargements of an inflorescence photograph taken at Coamo Springs by Mr. Dewey (pl. 77).
