TONELLA 



linear or narrower, 1-2 inches long, coarsely toothed or subpinnatifid to 

 entire, only the uppermost in whorls of 3-4 : peduncles 6-8 lines long, erect, 

 usually solitary: calyx about 3 lines long, cleft to the middle; the lobes 

 triangular, obtusish: corolla 4-5 lines long, violet; the lips about 2 lines 

 long: capsule ovoid, hardly as long as the calyx: seeds narrowly winged. 

 In wet places about Cold Camp, eastern Oregon. 



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 : 

 corolla 3-4 lines long, violet and white, but little declined ; the lips only a 

 line or two long, the upper one with a double callosity: gland subulate; 

 ovules only 2 in each cell : capsule globular, equalling the calyx ; seeds 

 meniscoidal, slightly wing-margined. On dry open hillsides, Washington 

 to California. 



C. linearis Gray 1. c. Minutely puberulent : stem slender, 6-12 inches 

 high,paniculately branched above: 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-lanceolate, acute : 

 corolla much declined, gibbous- saccate, 6-8 lines long, the light blue and 

 white lips longer than the tube and throat ; upper lip with a 2-lobed callus : 



fland filiform-subulate : ovules 3 in each cell : seeds very slightly margined. 

 n dry open places, southern Oregon to California. 



5 TONELLA Nutt. Gray Proc. Am. Acad. vii, 378. 



Small annual herbs with opposite leaves and small 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-tube. 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. T. 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' t by 

 deeper sinuses : ovules solitary in the cells : capsule globose, longer than 

 the calyx. Common in shady places, Krit. 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
