ColUnsia. SCROPHULARIACEiE. 256 



M. viscida, Gray. Erect annual, a span to 2 feut high, corymbosely branclied, pubescent 

 and veiy viscid: leaves lanceolate, entire, 2 inclies long, tapering to both ends, somewhat 

 petioled ; the lower opposite ; upper alternate : flowers short-pedicelled : sepals lanceolate, 

 acuminate, nearly equal : corolla inch and a half long, sulijhur-colored, with some purple 

 dots : capsule globular : seeds very numerous, oblong, smooth and even on the back ; the 

 ventral face deeply cup-shajjcd, with thickened somewhat corky sides. — Gravelly banks, 

 S. E. California and adjacent jiarts of Arizona: fl. early spring. 



7. COLLINSIA, Nutt. {Zaccheus Collins of Philadelphia, who published 



nothing, but was the most accurate botanist of his place and time.) — N. American 



winter-annuals, flowering early in spring and summer, low or slender ; with 



simple opposite sessile leaves, or the lowest petioled and the upper verticillate, 



the uppermost often reduced to subulate bracts. Flowers handsome, in series of 



cymosely umbellate fascicles or in whorls, or sometimes solitary in the axils ; the 



pedicels ebracteolate, and no common peduncle. Corolla not rarely 2-colored. 



The stamens and style occasionally rise out of the sac of the corolla into a more 



erect position before all the pollen is shed. Ovules and seeds usually few (G to 



2) and sometimes solitary in each cell. — Nutt, in Jour. Acad. Philad. i. 190, t. 9 ; 



Gray, Proc. Am. Acad. xi. 91, & Bot. Calif, i. o53. 



* Flowers short-pedicelled or almost sessile, verticillastrate-crowded, below in the axils of leaves, 

 above in the axils of bracts : corolla half to three-fourths inch long : seeds several or few, 

 meniscoulal. 



-i— Corolla strongly declined; the miicii-intlated and gibbous saccate body (which we denominate 

 the tin-oat) full as broad as long, and forming an obtuse or right angle with the very short proper 

 tube : gland short and small, sessile : upper pair of filaments more or less bearded toward the 

 base : ovules and seeds several. 



C. bicolor, Benth. A foot or so high, from nearly glabrous to hirsute, or above viscid- 

 pubescent : leaves more or less dentate and oblong or lanceolate ; the upper usually ovate- 

 lanceolate, sessile by a broad or subcordate and ncrvose base : pedicels shorter than the 

 acute calyx-lobes, mostly several in the fascicle ; corolla with lower lip violet or rose-pur- 

 ple and the upper paler or white (occasionally both white) ; saccate throat very oblique to 

 the tube ; recurved-spreading upper lip a little shorter than the lower ; seeds rugose-reticu- 

 lated. — Lindl. Bot. Reg. t. 173i; Don, Brit. Fl. Gard. ser. 2, t. 307; Hook. Bot. Mag. 

 t. 3488. C. heteroj)hi/lIa, Graham, Bot. Mag. t. 3695, rare form with lower leavos 3-clef t. — 

 Moist grounds, common through the western part of California. Commonly cultivated. 



C. tinctoria, Hart'Weg. Like the preceding, but with more glandular and viscid brown 

 or yellowish pubescence, which stains the fingers: flowers almost sessile: calyx-lobes lin- 

 ear or oblongdinear, mostly obtuse : corolla yellowish, cream-color, or white, usually with 

 some purple dots or lines ; axis of saccate throat forming a right angle with the tube ; the 

 upper lip and its lobes very short: seeds smaller, rounder, and smoother. — Benth. PI.

 1853, & Bot. Zeit. xii. 905. C. septemnervUi, Kellogg, Proc. Calif. Acad. ii. 224, fig. 09. — 

 Common in California, especially along the Sierra Nevada and its foot-hills. 



4— H— Corolla less declined or oblique; the gibbons throat much longer than broad : .stems only a 

 span or two high : leaves crenate or obtusely dentate, obtuse, thickish, seldom over an inch long. 



++ Filaments and interior of corolla somewhat iiearded : upper lip of the latter erestless, but with 

 transverse callosity : calyx-lobes rather broad and obtuse. 



C. bartsiaefolia, Benth. Puberulent and somewhat glandular, rarely hirsute-pubes- 

 cent above: stem strict: leaves from ovate-oblong to linear: flower-clusters 2 to 5 or 

 fewer: corolla purplish or whitish; its upper lip about the length of the curved gibbous 

 throat ; the lower with narrow base and emarginate or obcordatc lateral lobes : gland ses- 

 sile and elongated, porreet : seeds only a pair in each cell, smooth. — ]^C. Proilr. x. 318 ; 

 Gray, I.e. C. hirsuta, Kellogg, I.e. 110, fig. 34, a hirsute form. — Sandy soil, conmion 

 through California, less showy than j)receding. 



C. corymbosa, Herder. Almost glabrous, cespitose-branching from base and diffuse or 

 decumbent : leaves oblong or oval, very obtuse, rather fleshy : flowers maitdy in a soli-
