POLEMONIACEiE. 409 



G. prostrata, Gkat. Wholly depressed and liumifuse : primary capitulum-like glomerule 

 sessile and as if radical, soon proliferous into prostrate similar liowering branches: calyx- 

 tube sparsely hirsute: corollas (white) only half the size of the preceding : ovules 4 in each 

 cell. — Proc. Am. Acad. xvii. 223. — Low ground, IS. California, especially Los Angeles and 

 San Diego Co., Xevin, Parrij, Orcutt. 



G. divaricata, Torr., p. 142. Corolla very small, not surpassing the calyx-lobes : stamens 

 not exserted. — Mariposa Co., California to Washington 'J."err. 



G. filicaulis, Touk., p. 142. Stamens much exserted. 



G. viscidula, Gu.w, p. 142. Varies from obscurely to very viscid, and the corolla from 

 violet to whitish : stamens at length fully as long as the corolla-lobes, incurved in the bud : 

 ovules commonly 4 in each cell. — Common in California. 



Var. heterodoxa, G. heterodoxa, Greene, Bull. Calif. Acad. i. 10, is a branching form, 

 with more naked and spreading branchlets, broader bracts, and the stamens, according to 

 Greene, " strongly declined." Some indications of this are to be seen in dried specimens of 

 the present and tlie following species. — Calistoga, Parnj, Greene, and elsewhere. 



G. atractyloides, Steud., p. 142. From Santa Cruz to San Diego and .southward. Corolla 

 smaller than in the foregoing, from wholly violet to purplish or white, with or without 

 a purple throat : stamens shorter than the lobes. According to Orcutt, a form with white 

 flowers is scentless, while one with deep-colored corollas has a strong scent like that of 

 Pennyroyal or of Porioiiyne. 



§ 6^. CHyETOGiLiA. Flowers short-peduncled or siibses.sile in the forks of the 

 leafy-congested dwarf and at length depressed stem and branches, not bracteolate : 

 corolla salverform ; limb comparatively large, either regular or bilabiately irregu- 

 lar : stamens inserted close to the sinuses ; the filiform filaments cither straight or 

 strikingly declined-incurved : ovules 3 to 10 in each cell: winter annuals, with 

 pinnately lobed or toothed leaves, their teeth and the sei^als and mostly the leaf- 

 margins bearing long and slender white bristles. 



* Corolla regular and stamens straight, or nearly so. 



G- setosissima, Gray, p. 142. Slightly pubescent, glabratc : leaves all broader upward, 

 those (jf the branches cuneate and 3-5-lobed at summit: corolla light violet; its lobes often 

 dotted with purple (conspicuou.sly so only in dried specimens), obovate, obtuse, 3 to 5 lines 

 long, and with the short tiiroat almost equalling the tube : anthers oblong-oval : ovules 6 to 

 10 in each cell. — Exclude the syu. relating to the following. 



« * Corolla bilabiately more or less irrejxular (.3 and 2), and the stamens declined-incurved : 

 anthers short. — Laeselia, Gra^' in Bot. Calif, ii. 400. 



G. Schottii, Watsox. Roughisii-pubescent or below quite glabrous : cauline leaves linear ; 

 those of the branches and terminal clusters .slightly and gradually dilated ujiward and rather 

 3-toothed than lobed at the truncate apex: corolla " white " or " pinkish " ; its lobes small (at 

 most 2 lines long), oblong or lanceolate, acute, not half the length of the tube: stamens 

 moderately incurved : ovules 2 to 4 in each cell. — Bot. King Exp. 267. G. setosissinia, var. 

 exigua. Gray, Proc. Am. Acad. viii. 271. Navarretia Schottii, Torr. Bot. Mex. Bound. 145. 

 Laselia Schottii, Gray, Bot. Calif. I. c. — De.sert region of W. Arizona, S. E. California, 

 and S. W. Utah ; first coll. by Coulter, then by Srholt, in very exiguous specimens, which 

 hardly show the characters, later and better by Parri/, Lemmon, Parish, &c. Also loose 

 and slender specimens, from Sonora near the Gulf of California, are in the 1884 distribution 

 of PriiK/Ie, under the name of G. pohjcladon. 



G. Mattiiewsii. Pubescent or hirsute with crisped hairs, somewhat robust, at length form- 

 ing tufts a span to a foot in diameter: leaves nearly of the preceding: corolla jmrple or 

 whitish with violet throat or stripes, .strongly irregular; its lobes spatnlate or cuneate, with 

 obtuse or rctuso or tridentate apex, 3 or 4 lines long, nearly eijualling tlie tube: stamen.'? 

 conspicuously incurved: ovules 5 or 6 in each cell. — Locselia Maithewsii, Gray, Bot. Calif.
