Acalypha oreopola. Stem branched, purplish, bifarious-puberu- 

 lent : leaves petiolate, ovate, 1.5 to 5 cm. long, 1 to 3 cm. broad, acumi- 

 nate, acute, shallowly serrate-dentate, short-cordate, glabrous upon both 

 surfaces, pellucid-punctate, 3-7 -nerved ; petioles 0.5 to 3 cm. long, canal- 

 iculate, crisp-puberulent, purplish : inflorescence in terminal or axillary 

 rather remotely flowered glabrous spikes : bracts of the fertile flowers 

 2 to 3 mm. long, glabrous and pellucid-punctate, 3-6-lobed with triangu- 

 lar-acute lobes, 1— 3-flowered : calyx deeply 3-parted ; divisions ovate, 

 acute, sparingly pubescent : ovary hirsute above ; styles pectinately 

 divided : capsule triangularly and obtusely 3-lobed, about 2 mm. long, 

 muricately hispid above: seeds about 1 mm. long, smooth. — Mexico.

Jatropha Pseudo-Curcas, Muell. Arg. in Linnaea, xxxiv. 208, and 

 in DC. Prodr. xv. 2, 1080; Hemsl. Biol. Cent.-Am. Bot. hi. 108. 

 Specimens agreeing well with the description of this species were col- 

 lected by O. Conzatti and V. Gonzalez at Cercanias de Oaxaca, State of 

 Oaxaca, altitude 1550 m., June, 1901, no. 1207 (hb. Gr.). The leaves 

 in the specimens secured by Sefiors Conzatti and Gonzalez are somewhat 

 larger than is ascribed to the species by Mueller, having in many cases 

 leaves fully 2 dm. long and nearly or quite as broad. The fruit charac- 

 ters, which seem not to have been recorded hitherto, may be here pre- 

 sented, as follows: capsule oblong, 2 to 2.5 cm. long, 1 to 1.5 cm. in 

 diameter, abruptly short-acuminate, subtriangular, smooth and gla- 

 brous : seed oblong-elliptic, rather conspicuously carunculate, smooth 

 and shining. 



Manihot caudata. A small tree, 4 to 5 m. high: stem covered 

 with a brown or grayish-brown cortex : branches leafy at the summits : 

 leaves alternate, petiolate, ovate-rotund in general outline, cordate, pal- 

 mately and deeply 3-7-lobed, pale green and glabrous on both surfaces ; 

 lobes or divisions obovate to oblong, 3 to 9 cm. long, 2 to 4.5 cm. broad, 

 abruptly and conspicuously caudate-acuminate, entire ; the outer lower 

 lobes more or less oblique and usually horizontally spreading ; petioles 

 8 to 14 cm. long, terete or slightly canaliculate, and as well as the 

 peduncles, pedicels and lower leaf-surface near the nerves more or less 

 glaucous : racemes short, axillary, 5 to 6 cm. long in the fruiting stage ; 

 pedicels 1.5 to 3 cm. long : capsule 18 to 22 mm. in length : seeds oblong, 

 flattened, 12 to 15 mm. long, 8 to 12 mm. broad, more or less mottled 

 with brown or brownish-black subhorizontal markings ; caruncle broader 

 than long. — Manihot ?, Watson, Proc. Amer. Acad. xxi. 440. —
