74 AMARYLLLDACEAE. 



basal, or clustered at the top of the caudex, the large bracted flowers in 

 terminal spikes or compound clusters. Perianth tubular or funnelform, wither- 

 ing-persistent, with 6 equal or nearly equal lobes. Stamens inserted on the 

 perianth at the bases of the lobes, exserted. Ovary 3-celled; style slender, 

 exserted, 3-lobed; ovules numerous, in 2 rows in each cavity of the ovary. 

 Capsule 3-lobed, thick-walled, many-seeded. Seeds compressed, somewhat 

 cuneate, black. [Greek, signifying noble.] Perhaps 150 species. All these 

 plants, except the Sisal, are called "Bamboo" in the Bahamas. We have 

 copied here the original descriptions of the Bahama species by Professor Tre- 

 lease, who had all our specimens for his investigation, and we have nothing to 

 add to them.

 usually 5-10 mm. apart, 2-3 mm. long, straight or the lower gently recurved, 

 triangular, scarcely lenticular at base, the intervening margin straight, or con- 

 cave when they are raised on low green bases; inflorescence about 7 m. high, 

 paniculate; pedicels about 10 mm. long; flowers golden-yellow, 40-45 mm. 

 long; ovary 20 mm. long, nearly half as long again as the perianth, oblong- 

 fusiform; tube conical, about 7 mm. deep; segments 3-4 by 15-17 mm., three- 

 fourths as long as the ovary; filaments inserted nearly in the throat, 35 mm. 

 long, about twice as long as the segments; capsules broadly oblong, 20 by 35 

 mm., shortly stipitate and beaked ; seeds 6 by 8 mm. ; bulbils unknown.
