Guadalajara, May, 1891 (n. 5147). I am indebted to Mr. Hemsley 

 for the information that this plant is distinct from 2E. conferta, 

 Benth., and that it appears to be the same species as Seemann's 

 2189, collected in the Sierra Madre. In the Gray Herbarium 

 there is a similar plant collected by Seemann in the Sierra Madre, 

 and probably representing his 2189. It certainly seems to be spe- 

 cifically the same as Mr. Pringle's plant, although it represents a 

 somewhat different stage of growth. In it the leaves arise from 

 the stem, and the inflorescence is hirsute and less glandular. In 

 Mr. Pringle's plants the stem-leaves have all fallen, and the entire 

 foliage is crowded upon short secondary axes, giving the specimens 

 a rather different habit. 



Vigxa luteola, Benth., var. angustifolia. Stem appressed- 

 pubescent: leaflets lance-linear, rounded at the base, 1^—2 inches 

 long, about 3 lines broad: petioles short, not an inch in length. — 

 Wet places near Guadalajara, May, 1890 (n. 3188). 



Vigna strobilophora. Stem slender, flexuous, branched, cov- 

 ered with a fine soft pubescence : leaves pinnately trifoliate ; leaf- 

 lets ovate, acuminate, entire, rounded at the base, pubescent or 

 glabrate above, somewhat paler and soft-pubescent beneath, 2^- 

 inches long, half as broad; common petioles pubescent, 1£ inches 

 in length: peduncles axillary, rather stout, curved, bearing the 

 flowers in dense racemes: bracts large, ovate, sharply acuminate, 

 entire, scarious, finely striate, somewhat pubescent and ciliated 

 toward the apex, closely imbricated over the buds, deciduous: 

 pedicels single, silky-pubescent, 1-3 lines long: calyx campanu- 

 late, short, colored; teeth short and obtuse: corolla blue-purple, 

 6-7 lines in length; standard orbicular, slightly refuse, with two 

 scale-like appendages at the base; wings bluntly auriculate on the 

 upper side; keel bent nearly at right angles, the end then conspic- 

 uously curved inward: stamens diadelphous : style bearded on the 

 outer side near the end; stigma somewhat oblique. — Bluffs of 

 barranca near Guadalajara, September, 1891 (n. 5163). This spe- 

 cies is strongly characterized by its large closely imbricated 

 bracts. In its keel it is almost intermediate between Phaseolus 

 and Vigna. 



Cesalpinia MULTiFLORA. A medium-sized tree, minutely seri- 

 ceous on the younger parts : foliage and racemes crowded near the 

 ends of the branches; leaves 7 inches or more in length, bipinnate; 

 pinnae about 10 pairs; common petiole striate-sulcate, 3 inches 

 long; leaflets 15-18 pairs, elliptic-oblong, mucronate, entire, mod-
