entire to more or less palmately 3-7-lobecI, palmately 5-nerved, the 

 nerves conspicuous beneath ; petioles 1.5 to 4 cm. long, pubescent at tip : 

 inflorescence axillary or terminal ; the staminate ament linear-oblong, 

 2 cm. long, long-peduncled, with few strongly reflexed pistillate flowers 

 at base ; pedicel of pistillate flower glandular at base, thick-clavate, 1 to

 tains above Iguala, alt. 1,230 m., Sept. 26, 1900 (C. G. Pringle, no. 8433). 



Related to Dalembertia, Baillon, which differs in the single bract 

 (instead of a 3-lobed calyx) at tlie base of the anther. Also approaching 

 Tetraplandra, 'B-a.iU.OQ, and Maprounea^ Aublet, but the former is distin- 

 guished by its four terminal anthers, and the latter by its sbort staminate 

 sjDike and two more or less connate stamens. 



Euphorbia (Anisophyllum) puberula.^ Branching from the 

 base, the branches subligneous, ascending, 2.5 dm. or less high, puberu- 

 lent, the tips cauescent and tomentulose : leaves rhomboidal, 1 to 2 cm. 

 long, 0.5 to 1 cm. broad, very oblique, glaucous beneath, blunt, crenate- 

 serrate, sparingly pilose ; stipules setaceous : cymes dense, 1 or 2 cm, 

 broad, terminating the leafy branches : involucre white-pilose, turbinate- 

 campanulate, 1.5 to 2 mm. long, with deltoid hairy lobes; glands 4, 

 short-stipitate, with or without narrow appendages ; false gland absent 

 from the broad shallow sinus : capsule appressed-pilose, subacutely lobed, 

 1.5 mm. long: seed pulverulent, 1 mm. long, oblong or ovoid-oblong, 

 quadrangular, with somewhat broken ridges between the angles. — 

 Mexico without locality (^Coulter, no. 1438 in part): Guanajuato, hills 

 of Guanajuato, 1895 {A. Buges): Morelos, Puente de Ixtla, July 3, 

 1900 (Charles C. Beam, no. 26) ; Huerta de la Hacienda de Miacatlan, 

 Distr. Tetecala, Dec. 28, 1887 (C. & K Seler, no. 341): Oaxaca, near 

 Mitla, Distr. Tlacolula, June, 1888 ; Tecomavaca, Nov. 15, 1895 ;

 Distr. Tuxtla, Feb. 19, 1896 (C. & E. Seler, no. 1952). Nearest related 

 to £J. pilulifera, L., and E. lineata, Watson, differing from the former in 

 its terminal cymes and blunter leaves, from the latter in its rather 

 stouter habit and more rhomboidal leaves, and from both in its cinereous 

 puberulence. 



1 In the preparation of the descriptions of these Euphorbias the writer has 

 been greatly assisted by Professor C. F. Millspaugh, who has generously examined 

 tlie specimens, and who has already pointed out (Bot. Gaz. xxv. 13) the impor- 

 tance of the involucral appendages in differentiating the species of this genus.
