C. Rattani Gray Proc. Am. Acad. xx, 50. Somewhat cinereous with 
a very minute pubescence below, glandular above: stem slender, strictly 
erect, 6-18 inches high, sparingly branched above: lower leaves spatulate, » 
the blade 4-6 lines long, slender-petioled ; upper ones linear to almost fili- 
form, sessile by a broad base, entire, opposite or in whorls of 3-6, 1-2 inches 
long: pedicels about 6 lines long, erect, solitary or 3-6 in the upper whorls; 
calyx-lobes broadly lanceolate rather obtuse, about as long as the tube:

line or two long, the upper one with a double callosity: gland subulate; 
ovules only 2 in each cell: capsule globular, equailing the calyx; seeds

C. linearis Gray 1. c. Minutely puberulent: stem slender, 6-12 inches 
high, paniculately branchedabove: leaves all linear, 1-3 inches long, those 
of the inflorescence reduced to filiform bracts; all entire or the lowest ones 
obscurely dentate: pedicels slender, erect, 4-6 lines long: calyx less than 
3 lines long, cleft to below the middle, the lobes triangular-lanceo!ate, acute : 
corolla much declined, gibbous-saccate, 6-8 lines loug, the light blue and 
white BR longer than the tube and throat; upper lip with a 2-lobed callus:

5 TONELLA Nutt. Gray Proc. Am. Acad. vii, 378. 
Small annual herbs with opposite leaves andsmall flowers on 
filiform axillary naked peduncles. Calyx campanulate, 5-lobed, 
persistent. Corolla little declined, obscurely bilabiate, the 5 more 
or less unequal lobes somewhat rotately spreading, the lower not 
enclosing the soon ascending stamens: the tube slightly gibbous 
posteriorly. Filaments filiform the lower pair inserted on the 
corolla-tubé. Ovules and seeds 1 or 2 in each cell. Capsule sub- 
globose, septicidally dehiscent. Seeds ovate, convex on the back; 
the ventral face concave. 
T. collinsioides Nutt. Mss. 7. tenella Benth. in DC. Prodr. x, 293. 
Nearly glabrous: stem weak and filiform, diffusely branched from the base, 
6-12 inches long: lower leaves round or reniform in outline more_or less 
deeply 3-5-lobed or trifoliolate, on slender petioles longer than the blade, 
the others short-petioled or sessile, ovate to lanceolate, coarsely toothed 
to entire, many of them 3-parted or else quite divided into oblong or lan- 
ceolate divisions or leaflets; the uppermost in whorls of three, simple{and 
shorter than the long filiform pedicles: corolla blue, a line long, its 5 lobes 
of equal length, the lower one transversly oval or roundish very much 
larger than the oblong lateral and upper ones and separated from them{by 
deeper sinuses: ovules solitary in the cells: capsule globose, longer than 
the calyx. Common in shady places, Brit. Columbia to California. 
_T. floribunda Gray Proc. Am. Acad. vii, 378. Glabrous through- 
out: stem stout erect, 3-20 inches high, paniculately branched: lower leaves 
ovate mostly simple, on slender petioles ; most of the cauline 3-5-foliolate, 
the leaflets lanceolate to linear, 1-2 inches long: whorls numerous, in loose 
elongated racemes each of 3-10 flowers: calyx 2 lines long its subulate
