oblongis obovatisvc 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 

 ] O-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 squamellae also as in E. strictifloi'a. 

 — 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. 1 



281. Solanum mammosum, Linn. 1 ? Road-sides in prairies 

 between the Brazos and the Colorado. June. A stout 

 branching perennial, with broader, more canescent and lobed 

 leaves than S. Carolinense. 



282. Pentstemon 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 sphjerocarpa, Ell. Along ponds and riv- 



i Eutoca glabra = Phacelia glabra, Nutt. I. c. Of this a very few specimens 

 were collected by Lindheimer. Fine specimens in fruit exist in Drummond's Texan 

 Coll. III. No. 302. The capsule is about 6-seeded. The calyx-segments in fruit 

 become ovate-lanceolate or oblon?.
