to oblong-lanceolate, deeply pinnatifid, the narrow lobes very nar- 

 rowly acuminate, the smaller leaves only toothed or nearly entire : 

 sepals broadly oblong, acute, 4 lines long : stamens 10 or 15, the 

 filaments mostly very short (i to 1 line long) : style as long as or 

 longer than the stigmas ; fruit (immature) erect, 2 to 2^- lines long, 

 equalling the stipe. — In rich mountain canons near Lake Chapala, 

 Jalisco ; December, 1889 (n. 2445). 



Capsella (Hymenolobcs) stellata. Low and spreading, 

 somewhat woody below, rather rigidly much-branched, canescent 

 throughout with stellate pubescence : leaves narrowly oblanceolate, 

 entire or obscurely few-toothed, 6 lines long or less : racemes sessile ; 

 flowers white: pods elliptical, somewhat obcompressed with deeply 

 concave valves, stellate-pubescent, about 1| lines long and equalling 

 the divaricately spreading pedicels ; cells 3-4-seeded. — On limestone 

 ledges in Carneros Pass, Coahuila ; September, 1889 (n. 2844, 2848). 

 Habit nearly that of O. Mexicana ; style variable in length. 



Alsodeia parviitolta. a much branched leafy shrub : leaves 

 short-oblanceolate or narrow-rhombic, obtuse or acutish, cuneate at 

 base, serrulate, glabrous or slightly pubescent on the nerves beneath, 

 3 to 15 lines long, usually much exceeding the nodes: flowers solitary 

 in the axils, on pedicels 1 or 2 lines long, small (about a line long) : 

 fruit 2 lines long, the placentas 1 -seeded. — In the mountains east of 

 San Luis Potosi; 1890 (n. 3063). Remarkable for the numerous 

 short nodes of the branches and for its small leaves. 



PoLTGALA Pringlei. Tall and slender (1| or 2 feet high), 

 closely resembling P. paniculata, but glabrous throughout, the raceme 

 dense and narrowly cylindrical, and the smaller seed with a very mi- 

 nute hilum, nearly ecarunculate. — In wet places, plains of Guada- 

 lajara ; October and November, 1889 (n. 2148, 2452). Distributed 

 under the latter number as P. paniculata. 



Drymaria longepedunculata. Annual, very slender, the 

 elongated branching stems recumbent, clothed throughout with a soft 

 villous pubescence: leaves thin, broadly ovate, apiculate or shortly 

 acuminate, truncate to rounded or cuneate at base, 3 to 5 lines long : 

 peduncles axillary, elongated (1 to 3 inches), 1-3-flowered : flowers 

 large ; sepals thin, oblong-lanceolate, 2 lines long ; petals twice 

 longer, deeply parted and cleft : capsule stipitate. — Under ledges of 

 the barranca near Guadalajara; November, 1888 (n. 2121). Of the 

 D. gracilis group. 



Drymaria tenuis. Glabrous throughout, the stems very slender, 

 from a slender branching rootstock, a foot long or less : leaves thin,
