408 SUPPLEMENT. 



verform corolla, neither exserted nor declined : ovules solitary in the cells : 

 seed-coat with abundant spiracles except in one species : annuals, with neither 

 foliage nor calyx-lobes rigid or spinescent ; the leaves sessile and entire (except 

 some laciniation in G. coccinea, Collomia, Lehm., of Chili), the lower sometimes 

 opposite. CoUomia, Nutt. ; Benth. excl. spec. 



G. grandiflora, GKAY, Proc. Am. Acad. xvii. 223, not Steud. CoUomia yrandiflora, 

 IXmgl., &c.; Syu. Fl. ed. 1, 135. 



G. linear^S, GRAY, 1. c. CoUomia linearis, Nutt., &c. Passes by many gradations, and 

 equally viscid herbage, into 



Var. Subulata, G. tinctoria, Kellogg in Bull. Calif. Acad. i. 142. CoUomia linearis, 

 var. subulata, Gray, in part, of p. 135. 



G. aristella. A span high, with almost filiform and few-leaved stem and lax branches, mi- 

 nutely pubescent above and viscid : leaves lanceolate-linear and tapering to both ends (inch or 

 less long, a line or two wide) : flowers 1 to 3 in the forks and upper axils : corolla purple, 

 with filiform tube 4 to 6 lines long and small lobes : calyx-lobes (2 lines long) aristiform 

 from a triangular base: capsule obovate-3-lobed with attenuate base. CoUomia linearis, var. 

 subulata, p. 135, as to an attenuate form. Northern part of California, Greene, &c., and 

 Oregon, Kronkite, Cusick, to Washington Terr., Suksdorf, on bare hillsides. Habit of the 

 following, and of the most diminutive variety of the preceding : calyx-lobes truly attenuate 

 into an awn. 



G. leptotes, GRAY,!, c. CoUomia tenella, Gray, Proc. Am. Acad. viii. 259, &c. Known 



only from Parley's Park, Utah, coll. Watson. The Western plants which have been wrongly 



referred to it belong to the preceding. 

 G. gracilis, HOOK. CoUomia gracilis, Dougl., Beuth., &c. Peculiar in having so many of 



the leaves opposite, and in the absence of spiracles in the seed-coat, as mentioned on 



p. 135. 



5 2 . COURTOISIA. Flowers of Collomia (and as in that either scattered or 

 in foliose-bracteate clusters) ; foliage of Eugilia, the leaves from pinnately com- 

 pound to entire, the larger petioled : ovules from solitary to several in the cells. 

 Collomia Gilioides, Beuth. in DC. excl. spec., and one Navarretia. 



G. heterophylla, DOUGL. in Hook. Bot. Mag. t. 2895. Collomia heterophylla, Hook. 1. c. 

 Gilia Sessei, Don, Syst. iv. 245, fide Benth., but not Mexican. 



G. glutinosa. Collomia (jlutinosa and C. nilioides, Benth. Bot. Keg. 1833, & DC., &c. 

 C. gilioides, ed. 1, 135. Very variable in size, form and division of leaves, and degree of 

 viscidity, but apparently all of one species. 



G. capillaris, KELLOGG, Proc. Calif. Acad. v. 46. ^CoUomia leptalea, Gray, 1. c. & Syn. Fl. 

 ed. 1, 136. Varies extremely in size, some of it answering well to the specific name, some 

 more rigid and smaller-flowered ; the corolla from pink to almost white. Extends north- 

 ward to Washington Terr. 



6. NAVARRETIA, p. 141. Limb of corolla sometimes slightly irregular and 

 stamens somewhat unequally inserted : filaments straight, or in the last two 

 species incurved in the bud and somewhat so in anthesis. 



G. COtulaefolia, STECD., p. 141. Color of the corolla various, sometimes yellow and 

 purple. 



G. leucocephala, GRAY, p. 142. Wholly erect, or with procumbent branches from base of 

 primary stem, on which the first capitulum-like glomerule is more or less elevated : calyx- 

 tube nearly glabrous, except the ciliate fringe at the sinuses. Add the following closely 

 similar species :
