the broad conspicuous bracts (mostly 3 inches long) : fruit closely re- 

 sembling that of" i). Wheeleri. — At Monclova, Coahuila. 



Dastlirion acrotrichum, Zucc. At San Luis Potosi (500 

 Schaffner) ; 876 Parry & Palmer. Referred by me (Proc. Amer. 

 Acad. 14. 249) to D. graminifolium^ Zucc, but Mr. Baker is probably 

 more correct in considering it a form of D. acrotrichum. Known as 

 « CuchariUa." 



Anthericum stenocarpum, Baker. {Hesperanthes stenocarpa, 

 Watson.) At Lerios, Coahuila (2012). 



Anthericum leptophyllum, Baker. {Hesperanthes leptophylla, 

 "Watson.) In the San Miguelito Mountains, San Luis Potosi (543 

 Schaffner) ; 890 Parry & Palmer, in part. Mr. Bentham's judgment 

 is yielded to in retaining these species in Anthericum. 



Echeandia terniflora, Ort. At Guanajuato (Duges) ; 890 

 Parry & Palmer, in part. 



Glyphosperma * Palmeri. Glabrous : stem 1 or 2 feet high, 

 usually sparingly branched : leaves membranously sheathing at base, 

 6 to 1 inches long ; racemes loose ; pedicels erect, 2 or 3 lines long : 

 perianth-segments oblong, obtuse, 4 or 5 lines long, with a broad 

 brown midnerve : outer filaments a half shorter than the inner and 

 with a somewhat more dilated base : stigmas salmon-colored : capsule 

 2 lines long : seeds with 3 or 4 furrows on the back and usually 3 

 pits on each side. — In sandy valleys at Saltillo, Coahuila (1320), and 

 in cultivation at Cambridge. 



Hemiphylacus * LATiFOLius. Tubcrous roots dilated downward, 

 6 inches long or more ; caudex covered with the fibro-membranous 

 bases of old leaves: leaves thin, nearly a foot long, 8 to 12 lines 

 broad : stem sparingly branched, 2 feet high : racemes elongated, 



* The following new genera are proposed. The first, belonging to Ben- 

 tham's subtribe Antliericem, is remarkable for the large colored stigmas, the 

 peculiar filaments, the short dorsifixed anthers, the 1-nerved perianth-segments, 

 the pitted rugose seeds, and the terete fistulous leaves. The second, interme- 

 diate between the Chlororjalece and the Anthericew, is characterized especially by 

 the adnate filaments, only the inner and shorter ones antheriferous, and the 

 scarious l-nerved perianth-segments, in connection with the tuberous roo:8. 



GLYPHOSPERMA. Perianth-segments distinct, spreading, l-nerved, at 

 length connivent and soon deciduous, not twisted. Stamens 6, shorter than the 

 perianth, upon its base, filaments clavate above a dilated pubescent base, the 

 inner three longest ; anthers versatile, short-oblong, introrse. Ovary sessile, 

 globose : style shorter than the stamens, deciduous ; stigmas 3, obovate, colored: 

 ovules 2 in each cell, pendulous. Capsule thin-coriaceous, obovate, subtrique- 

 trous, 3-celled, loculicidal. Seeds 1 or 2 in each cell, triquetrous, dark ash-color, 

 strongly rugose across the back, pitted on the sides : embryo in fleshy albumen,
