the length of the lobes; appendages to the filaments 

 hairy. S. Calif. B.M. 4S13. F.S. 11:1085. G.C. 1854: 

 679. A beautiful species and much cult., with fls. an 

 inch long and nearly as wide; sometimes escaped in Eu. 

 Var. glcwrinioides, Voss (Whitlavia gloxinidides, Hort.), 

 has handsome white fls. with blue center. Var. alba, 

 Hort. (Whiilavia alba, Hort.), is white-fid. 



5. Parryi, Torr. Annual, rather slender, 9-18 in. 

 high: Ivs. ovate, irregularly and incisely double-toothed 

 or laciniate, or the lowest sometimes pinnately parted; 

 the upper cauline longer than their petioles: corolla cleft 

 beyond the middle, deep violet, 8 lines across; filaments 

 bearded: ovules on each placenta 20-30; seeds 15-20. 

 Calif. B.M. 6S42. G.C. II. 24:716. Gt. 34:1207. 



6. campanularia, Gray. Annual, lower than the last: 

 Ivs. subcordate or cordate, less deeply dentate: tube of 

 the truly campanulate corolla }$ai. long, expanded at 

 throat, barely twice the length of the lobes; appendages 

 to the filaments glabrous and smaller, otherwise much 

 like Xo. 4 and almost as showy. S. Calif. B.M. 6735. 

 G.C. II. 20:135; III. 55:173. F. 1883:145. Gn. 31, p. 

 554; 55:36. P. campanulata, Hort., is presumably 

 this plant. 



cc. Appendages in corolla 10. 

 D. Ovules numerous, or more than 2, on each placenta. 



7. linearis, Holz. (Hydrophyllum lineare, Pursh. 

 Eutoca ^fenz^esii, R. Br. P. Menziesii, Torr. Eutoca 

 multiflbra, Douglas). Annual and perhaps perennial, 

 9-12 in. high, at length paniculate-branched, hispid or 

 roughish hirsute, usually also minutely cinereous- 

 pubescent: Ivs. mostly sessile, linear or lanceolate, 

 entire or a few of them deeply cleft, with few or single 

 linear or lanceolate entire lobes: spikes or spike-like 

 racemes thyrsoid-paniculate, at length elongated and 

 erect; corolla bright violet or sometimes white; ovules 

 12-16: caps, shorter than the calyx; seeds oblong, 

 coarsely favose-reticulated. Calif, to Wash., and east 

 to Mont, and Utah. B.R. 1180. B.M. 3762. A beauti- 

 ful species, and easily cult. 



8. divaricata, Gray (Eutoca divaricata, Benth. E. 

 mexicana, Hort.). Diffusely spreading annual, a span 

 high, more or less hirsute and pubescent : Ivs. ovate or 

 oblong, mostly longer than the petiole, sometimes 1-2- 

 toothed or lobed at base, the runs curving upward: 

 spikes or racemes at length loose; the pedicels usually

(XH) 



much shorter than the calyx; style 2-cleft at apex: 

 ovules 12-20 on each placenta. Calif. B.M. 3706. 

 .R. 1784. Var. Wrangeliana, A. DC. Fig. 2885. 

 Differs from the type hi having the Ivs. inclined to be 

 lobed or 1-2-toothed. It is known to the trade as 

 Eutoca Wrangeliana, Fisch. &. Mey. P.M. 5:199. 



2885. Phacelia divaricata var. 

 Wrangeliana. (X>i) 



DD. Ovules only 2 on each placenta. 



E. Lvs. all simple and entire (except perhaps the 

 lowest). 



9. humilis, Torr. & Gray. Annual, unbranched or 

 branched from the base, 2-6 in. high, pubescent or infi. 

 often hirsute: Ivs. spatulate, oblong or oblanceolate, 

 generally obtuse, the lower rarely with 1-2 ascending 

 lobes: spikes loosely paniculate or solitary; corolla 

 indigo-blue, rather deeply lobed, surpassing the usually 

 linear calyx-lobes; filaments moderately exserted, 

 glabrous or sparingly bearded above. Calif, to Wash. 

 A pretty little plant. 



EE. Lvs. oblong or narrower, pinnately toothed to 

 compound. 



10. bipinnatifida, Michx. Biennial, erect, branche_d, 

 1-2 ft., viscid above: Ivs. with slender petioles, to 5 in. 

 long, pinnatifid, with 3-7 ovate or oblong dentate or 

 pinnatifid segms. : fls. violet or blue, J^in. or more broad, 

 in loose racemes which are little scirpioid; calyx-lobes 

 linear; corolla rotate-campanulate with conspicuous 

 ciliate appendages in pairs between the stamens. X. C. 

 to Mo. and south. 



11. glanduldsa, Xutt. (Eutoca glanduldsa, Hook.). 

 Viscid-pubescent and glandular annual, softly if at all 

 hirsute, 9-12 in. or more high: Ivs. irregularly and inter- 

 ruptedly 2-pinnatifid, or below divided; the numerous 

 lobes oblong, small, somewhat incised, obtuse: calyx- 

 lobes oblong or spatulate; corolla about 2 lines long, 

 bluish, purplish or white, with lobes shorter than the 

 tube; stamens and 2-cleft style moderately or conspicu- 

 ously exserted : seeds with the minute reticulations even. 

 Texas to Ariz, and north to Mont.
