Tonella. SCROPHULARIACE^. 257 



pedicels solitary or above 2 to 5 in the whorl, usually longer than the flowers : calyx- 

 lobes lanceolate or triangular-subulate, usually almost equalling the blue (or partly 

 white) corolla, hardly longer than the mature capsule: filaments glabrous: gland small, 

 capitate, short-stipitate : seeds thickish, marginless. Lindl. Bot. Reg. 1. 1802; Hook. Fl. 

 ii. 94 (misprinted C. paucijiora) ; Gray, 1. c. Shady moist grounds, Upper Michigan (shore 

 of L. Superior) to the Pacific in Washington Territory, and south to Arizona and Utah. 

 C. minima, Nutt, in Jour. Acad. Philad. vii. 47, of N. W". Rocky Mountains, is ambiguous, 

 but apparently a dwarf and large-flowered form of .C. parL'iflora, with corolla proportion- 

 ally longer, 3 or 4 lines long. 



-I -1 Calyx-lobes obtuse: corolla (blue) 3 or 4 lines long, fully twice the length of the calyx: 

 filaments 'glabrous : gland subulate or conical: stem slender, only a span or so high. 



+-1- Not glandular nor viscid : ovules and usually seeds 6 or 7 in each cell ; the latter round-oval, 

 when young discoidal, reticulated. 



C. Parryi. Puberulent : stem strict, simple : leaves (less than an inch long) lanceolate- 

 linear, obtuse ; the upper mostly entire and closely sessile ; the lowest smaller, narrowly 

 oblong, crenate, petioled : pedicels solitary, in pairs, or the upper in threes, as long as the 

 flowers : calyx-lobes oblong, equalling the moderately oblique throat of the deep blue 

 corolla, not exceeding the capsule : lips of the corolla almost equal in length, not longer 

 than the throat ; the lobes emarginate. San Bernardino Co., South-eastern California, 

 Parry, Leuuiion (no. 296). 



H. +-t- Filiform pedicels and upper part of the stems more or less glandular-pubescent and viscid : 

 ovules solitary in the cells: seed oblong, thick, almost terete, somewhat arcuate, smooth: calyx 

 shorter than the throat of the corolla. 



C. Childii, Parry, Herb. Stein mostly simple, puberulent : leaves thinnish; the lower 

 obovate-rotund or oblong, obtusely more or less serrate, petioled; the upper oblong-lanceo- 

 late with narrowed base, subsessile : flowers rather few : pedicels and calyx pubescent and 

 partly glandular : lobes of the latter lanceolate or oblong, surpassing the capsule : corolla 

 light blue; the oblong moderately oblique throat longer than the lips, the lobes of which 

 are of about equal length and entire. South-eastern California, in deep woods (of Libo- 

 cedrusdecurrens) in the San Bernardino Mountains, Parry & Lemmon, H. S. Child. Also Kern 

 Co., Kennedy. 



C. Torreyi, Gray. Stem divergently much branched, very floriferous: slender branches 

 and pedicels viscid-glandular: leaves thickish, linear with attenuate base and entire, or the 

 lowest spatulate or oblong and petioled ; floral mainly reduced to subulate 3-4-nate bracts 

 subtending whorls of 3 to 6 deep blue or violet flowers : corolla rather strongly declined, 

 thrice the length of the calyx, the lobes of which are shorter than the capsule ; upper lip 

 equalling and the lower longer than the ventricose throat. Proc. Arn. Acad. vii. 378, & 

 Bot. Calif. I.e. California, in open woods, through the Sierra Nevada from Mariposa 

 Co. northward to Siskiyou Co. 



8. TONELLA, Nutt. (An unexplained and probably quite meaningless 

 name.) Two known species, slender annuals, small-flowered, with the habit of 

 Collinsia. Gray, Proc. Am. Acad. vii. 378, xi. 92, & Bot. Calif, i. 555. 



T. collinsioid.es, Nutt. Diffuse, nearly glabrous : filiform branches a span to a foot 

 long: radical and lowest cauline leaves ovate or roundish (3 to 6 lines long), slender- 

 petioled, mostty entire ; the others shorter-petioled or sessile, many of them 3-parted or 

 else quite divided into oblong or lanceolate divisions or leaflets; the floral in whorls of 

 three; uppermost simple and shorter than the slender filiform (solitary, geminate, or some- 

 times ternate) pedicels: flowers minute: corolla blue, a line long; its 5 lobes of equal 

 length ; the lower one transversely oval or roundish, very much larger than the oblong 

 lateral and upper ones, and separated from them by deeper sinuses : ovules solitary in each 

 cell : capsule exceeding the calyx. Collinsia tenella, Benth. in DC. Prodr. x. 593, where 

 the mss. name of Tonella collinsioides of Nuttall is cited. N. California and Oregon, in 

 shady places. 



T. floriblinda, Gray, 1. c. Larger, a foot or two high : most of the cauline leaves 3-5- 

 foliolate : whorls numerous in a loose elongated raceme, each of 3 to "flowers: corolla 

 larger, more rotate, 3 or 4 lines broad, much exceeding the calyx, purple ; the three lobes <;f
