slightly twining, covered with fuscous retrorse-hispid pubescence : stip- 

 ules ovate to lanceolate, 4 to 6 mm. long: petioles retrorse-hispid, 1.5 to 

 2.5 cm. long ; leaflets oblong-ovate to obovate, mucronate, slightly strigose 

 above, pale and hispidulous beneath, 2 to 4 cm. long, the terminal on a 

 petiolule (0.5 cm.) thrice as long as those of the lateral leaflets : umbels 

 3-6-flowered, the principal peduncles 4 to 6 cm. long, retrorse-hispid, 

 those on the flexuous branches shorter ; pedicels 1 to 1.75 cm. long : 

 calyx 1 to 1.2 cm. long, hispid: corolla violet, 2 to 2.5 cm. long. — 

 MoRELOS, Cuernavaca, July 7, 1900 (C C. Dcam^ no. 40). Unique in 

 its long peduncles. 



Platanus glabrata. Leaves from broad-cuneate to subcordate, 

 unequally 5-9-lobed, the middle lobe and the upper pair of lateral ones 

 long-acuminate, the lower ones short-acuminate ; the margin entire ; at 

 first closely cinereous-tomentose beneath, soon becoming glabrate : pedun- 

 cles 0.5 to 1 dm. long, bearing 1 or 2 heads 1.5 to 2 cm. in diameter.

 April 24, 1900 (C. G. Pringle, no. 8319). Differing much from P. 

 Lindenia7ia of southern Mexico, which has the less lobed leaves perma- 

 nently cinereous beneath, and the heads more numerous. 



Croton Palmeri, Watson, var. ovalis. Leaves oval, 1.5 to 3 cm. 

 broad, not lanceolate, rounded at base : clusters many-flowered. — NuEvo 

 Leo\, Monterey, Oct. 11, 1895 (C & E. Seler, no. 1047). 



Alcoceria, nov. gen. of Eiiphorbiaceae (^Hippomaneai^). Monoecious. 

 Staminate flowers in a terminal ament; the individual flowers slightly 

 imbedded at base by close dens6 pubescence. Calyx of staminate flower 

 with 2 broad fleshy valvate sepals and a third narrow inconspicuous one. 

 Stamen solitary ; filament thick, columnar ; anther 2-celled, longitudinally 

 dehiscent, dorsally aflixed toward the sheathing tip of the filament. 

 Calyx of pistillate flower with three deltoid-subulate teeth and few or no 

 intermediate small glands. Ovary depressed-globose, suhtrigonous, the 

 three 1-ovulate cells alternating with the calyx-teeth. Style cylindric, 

 erect, equalling the three recurved branches. Fruit a 3-locular capsule. 

 Seed pisiform, scarcely carunculate. — Dedicated to Gabriel Alcocer, 

 acute observer, teacher in the Escuela Preparatoria, and botanist at the 

 Museo Nacional and the Instituto Medico Nacional of Mexico. 



A. Pringlei. Slender shrub, 3 to 5 ra. high, the sprawling branches 

 herbaceous, striate, the lower nodes remote : leaves pilose or glabrate 

 beneath, reniform, acuminate, varying from 0.4 to 1.3 dm. long, and from
