oblongis obovatisve membranaceis pinnatifido-dentatis vel in- 
cisis basi angustatis sessilibus vel infimis petiolatis, dentibus 
subovatis obtusis ; racemis terminalibus simplicibus secundis ; 
calycis laciniis oblongis, fructiferis subspathulatis patulis pedi- 
cello filiformi patente seu reflexo multum brevioribus ; corolla 
late campanulata calycem parum excedentibus, tubo obscure 
10-squamigero ; filamentis pilosiusculis inclusis ; ovario 14—16- 
ovulato ; capsula circiter 12-sperma.— Woods near San Fe- 
lipe. March—April. Stems 6 to 12 inches long, often de- 
cumbent. Whole plant with somewhat the habit of Eutoca 
viscida, but not glandular. Leaves 1 to 2 inches long. Ra- 
cemes lax; the spreading pedicels an inch long in fruit. 
Corolla much smaller than in the foregoing species, deep blue, 
yellow at the base ; the margin of the lobes somewhat erose ; 
the 5 pairs of very small squamellz also as in E. strictiflora. 
— We can discern the obscure rudiments of the tubal ap- 
pendages in the corolla of Eutoca viscida. In E. hirsuta 
(Phacelia, Nutt.) No. 134 of this collection, they are very 
narrow but are distinctly visible under the microscope ; as 
also in the nearly allied E. parviflora. Hence we should 
have no hesitation in restoring the genus Cosmanthus of 
Nolte and Alph. DC. to Eutoca and Phacelia.’ 
281. Sonanum mammosum, Linn.?? Road-sides in prairies 
between the Brazos and the Colorado. June. A stout 
branching perennial, with broader, more canescent and lobed 
leaves than SS. Carolinense. 
282. Penrstemon Murrayanum, Hook. Bot. Mag. t. 3472. 
Dry sandy soil in open woods west of the Brazos. May — 
June. The splendid flame-colored flowers, with a scarlet bor- 
der, form a pleasing contrast with the bluish glaucous leaves. 
Pedicels erect, the flowers horizontal. 
283. GraTioLa spHmRocARPA, Ell. Along ponds and riv- 
1 Euroca GLAsrA = Phacelia glabra, Nuit. l.c. Of this a very few specimens 
were collected by Lindheimer. Fine specimens in fruit exist in Drummond’s Texan 
Coll. 111. No. 302. The capsule is about 6-seeded. The calyx-segments in fruit 
become ovate-lanceolate or oblong.
