springing from the forks of the branches; peduncles but 1-2 lines 
long: calyx in anthesis 1} lines long, glandular-villous ; teeth short, 
ovate, acute: corolla apparently white, with dark spots at the base, 
2-3 lines long: anthers greenish-blue : fruiting calyx about } inch in 
diameter. — First collected by Mr. W. G. Wright near Mazatlan, 
January, 1889 (no. 1252); then by Dr. Edward Palmer, at Alamos, 
September 16-30, 1890 (no. 709, mentioned by Dr. Rose, Contr. 
Nat. Herb. i. 108), and finally collected by Mr. Pringle in the bar- 
ranca of Tepic, 11 October, 1893. This species differs from any 
known to the authors in its very thin, quite entire, exactly ovate and 
sharply acuminate leaves, as well as in its small subsessile flowers. 
The following imperfectly described species may well be related: 
P. geniculatd, Miers, which, however, is said to have obtusish leaves 
and peduncles equalling the petioles; P. glabra, Mart. & Gal., which 
also has peduncles equalling the petioles; and P. minutiflora, Mog. & 
Sesse, with repand acute pruinous leaves. 
JACOBINIA STELLATA.  Stellate - tomentose : stems ligneous, 
branched, light colored, not constricted about the nodes: leaves ovate- 
lanceolate, 14—4 inches long, two fifths as broad, narrowed to an obtuse 
apex, cuneate at the base, paler beneath; petioles 5-8 lines long: 
inflorescences short, crowded, pedunculate in the upper axils, glandular- 
pubescent ; bracts narrowly elliptic, cuneate, foliaceous, 5 lines long : 
calyx segments linear-oblanceolate, acutish, 1-nerved, 8 lines long, a line 
broad: corolla 1} inches or more 1n length, slender, reddish purple; 
the lower lip spreading, 6 lines long; the upper erect, a little shorter : 
fruit glandular-pubescent, a little over a half an inch in length. — 
Collected under dry cliffs in the barranca of Tequila, 16 October, 
1893 (no. 4573). Well characterized by its pubescence. 
CaRLowrIGHTIA HAPALOCARPA. Rootstock horizontal, much 
branched: stems erect, or nearly so, 10-15 inches high, tomentulose 
and slightly hirsute, with a few longer spreading hairs: leaves short- 
petioled, ovate, acute, 1-1} inches long, 9-12 lines broad, hirsute 
Upon the veins and margin, paler beneath: flowers in pairs, forming 
loose subsimple terminal spikes; bracts minute: calyx glandular- 
pubescent ; segments linear-oblong, acutish, 1-1} lines long: corolla 
pale purple, nearly $ an inch in length: anther cells slightly oblique: 
fruit tomentulose ; seeds flat, black, finely tuberculate. — Collected on
