the Eio Grande. Eoot 0-8 lines in diameter, 4-6 inches long, black, with long thick white 

 fibres. Leaves 4-6 inches long, \ an inch wide, deeply channelled, but not carinate, very 

 glaucous, the dark greenish brown blotches more distinct on the upper than the lower surface. 

 Scape l|-2 feet high. 8pike about 6 inches long, with 12-15 flowers. Bracts subulate, longer 

 than the pedicel, which is about one line long and articulated in the middle. The flowers, 

 which are of musky not disagreeable 0(Jor_, are about 20''' long ; ovary 6'^', tube 9'", the limb about 

 6'". Lacini^e of the perianth at first green, afterwards on both sides (with the filaments) of a 

 dirty purplish color Evidently near A. revoluta, Klotzscli; but that species has smooth-mar- 

 gined leaves ; limb of the perianth equal to the tube ; stamens free in the tube and longer than 

 the limb. To Polyanthes Mexicana, Zucc. (which Kunth in Enum. 5, p. 847, says, is probably 

 a species of Agave) it is still more nearly related, but that has leaves entire on the margin, 

 with reddish dots ; flowers white, in pairs and sessile, the tube 18 lines long, segments only 

 3-4 lines long. Capsule (immature) ovate- oblong obtusely triangular. Nothing is said of the 

 fragrance of the flowers.

TiLLANDSiA RECURVATA [Linn.; Le Conte in Ann. Lye. N. YorJc^ 2, y, 132): ca>spitosa; foliis 

 subdistichis filiformibus teretibus anguste canaliculatis cinereo-lepidotis recurvatis ; pedunculis 

 folio longioribus unifloris glabriusculis ; bracteis 2-3 acuminatis calyce longioribus. — On trees 

 near the Rio Coleto, Texas ; Thiirher. On oaks and grape vines, Los Moros ; Bigelow. Lower 

 Rio Grande ; Schott. San Fernando, Mexico ; Berlandier^ No. 818. The specimens are all in 

 fruit, and the peduncles mostly one-flowered.

Dasyliriox tenuifolium (n. sp.): caudice brevissimo; foliis linearibus gramineis planis vix 

 rigidulis nitidis margine spinuloso-scaberrimis; panicula elongata, ramis simplicibus distantibus 

 sublaxifloris, basi subnudis ; pedicellis flore sublongioribus ; fructibus membranaceis, lobis 

 carinatis vix alatis; seminibus oblongo-obovatis. Among rocks, borders of the Sabinal river ; 

 Wrighty (No. 1919.) Stony places on the high plateau of the upper Guadalupe, Texas ; Lind- 

 heimer. Caudex short and almost subterranean. Radical leaves about a foot long, 2-2^ lines 

 wide, bright green and shining on both sides, much thinner in texture than in any other species 



of this genus, those of the scape gradually smaller. Stem or scape (including the panicle) about 

 3 feet high. Branches of the panicle 2-3 inches long. Flowers solitary or somewhat fascicu- 

 late. Perianth scarcely a line and a half in diameter. Ovary 3 -celled, with 2 erect ovules in 

 each cell ; stigmas 3, oblong, sessile. Fruit rather broader than long, S-lobed, one or two of the 

 seeds commonly abortive. Seed minutely reticulate-rugose. Remarkable for the thin leaves 

 and long naked panicle.

 leaves. Scape 6-8 feet high. Flowers in a long dense panicle of close spikes, which are sub-

 ovary, and the female with sterile anthers. Bracts and bracteoles broadly ovate, acuminate
