rather coarsely crenate-serrate, aeutish or obtuse, 1 to 3 inches long, 

 the terminal rhombic-obovate and petiolulate, the lateral obovate or 

 elliptical and sessile : panicle stout, tomentose, equalling the leaves : 

 flowers nearly sessile: sepals and fruit pubescent ; wings ascending, 

 6 lines long. — Same locality ; December, 1889, in fruit (u. 2567). 



Staphylea Pringlei. Resembling S. trifolia ; lateral leaflets 

 somewhat more rounded and unequal at base : capsule very broadly 

 elliptical or nearly orbicular in outline, acute, 1^ to 2 inches long : 

 seeds much larger (3 lines in diameter), dull, with a broad deep scar 

 at base. — In canons of the Sierra Madre, near Monterey; July, 

 1888, in fruit (n. 1936). 



Lupixus EiiMiNEUs. Perennial, stout and leafy, white through- 

 out with very dense short-villous pubescence, appressed on the leaves 

 and pods, elsewhere mostly spreading: leaflets usually 7, oblanceo- 

 late. acute, 15 lines long or less, somewhat shorter than the petioles: 

 racemes nearly sessile, many-flowered, becoming much elongated ; 

 bracts linear, equalling the calyx, deciduoHS ; pedicels very short 

 (2 or 3 lines long in fruit) : calyx scarcely gibbous at base, very 

 villous, 3 lines long, the broad purple corolla 4 or 5 lines long : pod 

 6-seeded, an inch long by 3 lines broad. — Gravelly banks of streams 

 near Zacatecas ; October, 1888 (n. 1762). Near L. Palmeri and 

 L. niveus, distinguished especially by the more villous character of 

 the dense white pubescence. 



Dalea capitata. Woody, diffusely much branched, a foot high, 

 glabrous or slightly puberulent : leaves small, the 5 to 9 leaflets ^ to 

 1|^ lines long, obovate, emarginate: spikes capitate, dense, on very 

 short terminal peduncles ; bracts broadly ovate, acute or short-acumi- 

 nate, subpersistent, equalling the campanulate scarcely nerved pubes- 

 cent calyx: calyx-teeth acute; petals yellowish, 3 lines long: pod 

 pubescent, included. — At Carneros Pass, Coahuila; September, 1889 

 (n. 2378). With the habit of D. frutescens. 



Brongniartia nudiflora. Shrubby, with the branchlets densely 

 villous-pubescent and usually flexuous : leaves 4 or 5 inches long, of 

 4 to 6 pairs of oblong acute subcoriaceous and strongly reticulated 

 leaflets, sparingly pubescent beneath and ciliate, 1 or 2 inches long ; 

 8tii)ules deciduous : flowers apparently loosely racemose, in fascicles 

 of 1 to 6, each fascicle subtended by a pair of thin villous semicordate 

 stipule-like bracts; calyx and pedicels (each about ^ inch long) green 

 and glabrous; corolla dark purple, 10 lines long: young pods gla- 

 brous, flat, attenuate below, 6-8-ovuled. — On rocky hills near Gua- 

 dalajara; November and December, 1889 (n. 2128, 2980).
