Mr. Pringle's plant above cited was in the Gray Herbarium referred 

 by the writer to Anthericum Humboldtii, Hemsley (Phalangium cilia- 

 turn, HBK., Nov. Gen. & Sp. i. 276, & vii. t. 676), but that species is 

 a native of South America, first collected near Caracas, Venezuela, and 

 has straight leaves 10 to 13 cm. long, 6 to 7 mm. broad, and is said to 

 have white flowers. 



Anthericum durangense. Roots tuberous, fascicled : leaves basal, 

 lanceolate, 1.5 to 2.5 dm. long, 1.5 to 2 cm. broad, acuminate, acute, 

 ciliate, dark green and glabrous on both surfaces : scape 4 to 5 dm. high, 

 simple or branched, glabrous, or slightly hirtellous, usually unibracteate : 

 floral bracts ovate, mostly acuminate, hyaline, nerved, greenish-white : 

 pedicels jointed : perianth yellow, or yellowish-white in the dried state ; 

 divisions at the period of anthesis about 1.5 cm. long, 3-nerved. — 

 Mexico. State of Durango: near El Salta, altitude 2440 to 2650 m., 

 12 July, 1898, E. W. Nelson, no. 4544 (hb. U. S. Nat. Mus., and 

 hb. Gr.). 



Var. trachycaulum. Leaves in outline and size like the type, 

 yellowish-green, ciliolate-scabrellous on the margins : scape hirtellous 

 even to the flowers : perianth somewhat smaller than in the species

 State of Durango: Ramos to Inde, 11-14 August, 1898, E. W. Nelson,

Anthericum Nelsonii. Roots tuberous, fascicled : leaves basal, 

 narrowly lanceolate, 4 to 9 cm. long, 3 to 7 mm. broad, glabrous on 

 both surfaces, minutely scabrellous on the subcartilaginous margins : 

 scape 1 to 2 dm. high, glabrous, naked or bearing a single greenish-white 

 nerved bract near or somewhat above the middle, terminated by 1 to 3 

 flowers : floral bracts scarious, greenish-white, nerved : pedicels 0.5 to 

 1 cm. in length, jointed in the middle : perianth yellow or in the dried 

 state yellowish-white; divisions 8 to 10 mm. long, 3-nerved, obtusish or 

 somewhat rounded at the apex : stamens nearly or quite as long as the 

 perianth ; anthers free : capsule about 1 cm. long. — Mexico. State
