the lower lip rounded : anther-cells nearly equal in size, the upper not 

 ciliate, minutely mucionate at the base, the lower with a conspicuous 

 spur: capsule 5 lines long, soft-pubesceut, 4-seeded; seeds compressed, 

 very hairy especially at the edge. — On hills near Guadalajara; Oc- 

 tober, 1889 (n. 2967). This species seems anomalous among the 

 New "World members of the genus. It resembles more nearly the 

 species of the § Rhaphidospora of the Old World, which have a diffuse 

 inflorescence and echinate-hispid seeds. It differs from § Sarotheca 

 chiefly in lacking the ciliation of the anthers. 



CiTiiAREXYLU.At Berlandieri. Ten to fifteen feet high; branches 

 gray, striate ; branchlets pubescent, striate, acutely 4-angled but soon 

 becoming round ; leaves ovate or rhombic, varying in the same indi- 

 vidual from acute to refuse at the apex, shortly cuneate at base, mem- 

 branaceous, puberulent above, soft-pubescent beneath, 1 to If inches 

 long, 9 lines broad, entire, or some with a few blunt teeth near the 

 apex ; inflorescence termhial, subspicate, more or less flexuous, 1 to 2 

 inches long, becoming more rigid in fruit; pedicels half a line long, 

 with minute filiform bractlets of the same length: calyx turbinate, 2 

 lines long, striate, pubescent, the five subequal teeth erect, very short 

 and blunt; corolla-tube just equalling the calyx, pubescent within, the 

 spreading limb of five rounded lobes, puberulent on both sides : fertile 

 stamens four, filaments hairy; the fifth stamen present as an an- 

 therless rudiment: drupes dark brown, as large as peas, crowded in 

 the spikes. — Rocky hills. Las Canoas, San Luis Potosi ; July, 1890 

 (n. 3222). Apparently identical with n. 3182 of Berlandier, coUectecf 

 near INIatamoras, May, 1832. This specimen of Berlandier's was 

 doubtfully referred by Dr. Gray to C villosum, Jacq., and has formed 

 the sole evidence that this species occurs in Mexico. In the light of 

 ]\Ir. Pringle's better material, however, it is clear that the Mexican 

 plant is quite distinct from the species just mentioned. 



Scutellaria hispidula. Perennial with ligneous base; stems 

 numerous, mostly sim[)le, hispidulous, a span high, often dark purple as 

 well as the floral leaves and calyx : leaves small, ovate or ovate-elliptic, 

 subglahrous or very minutely hispid but not at all cinereous-pubes- 

 cent, 4 to 5 lines long (about half the length of the internodes), 2 to 

 3 lines broad, all except the very lowest abrupt at the base and sessile : 

 flowers numerous, of medium size, with short pedicels ; calyx strongly 

 accrescent, hispid with short white hairs ; corolla blue, white in the 

 throat, soft-pubescent on the outside, 5 to 7 linos long, the upper lip 

 but slightly cucuUate ; upper stamens often exserted. — Meadows, Flor 

 de Maria, ^lexico ; August, 1890 (n. 3233). A plant with the habit
