CAMPANULACE M. 229 



r inlet lobes, the, undivided part yellow, with white border; divisions of the 

 upper lip spreading and divergent, of broad-lanceolate outline. With 

 the preceding, and a more profusely flowering species. May. 



3. B. tricolor, Greene. Branches few, weak, tortuous and reclining: 

 lower lip of corolla parted into 3 equal broadly obovate truncate and 

 slightly cuspidate lobes, these deep blue at tip, white below, the undi- 

 vided part with a transverse somewhat quadrate spot of dark maroon; 

 upper lip of 2 small segments somewhat recurved, but parallel. Plains 

 near Suisun. May. 



4. B. concolor, Greene. Bather firm branches 35 in. high, very 

 numerous and for ruing a dense tuft; the herbage very minutely puberu- 

 lent: corolla violet almost throughout, but base of lower lip very dark and 

 this spot circumscribed by lighter blue, the lobes slightly unequal, very 

 obtuse and somewhat cuspidate; upper lip cleft to the middle only, the 

 lobes lanceolate, more or less deflexed. Low grain fields near Suisun. 



5. B. ornatissima, Greene. Slender, 6 10 in. high, mostly simple, 

 erect and rather strict: corolla pale throughout; lobes of lower lip some- 

 what obcordate and cuspidate, the undivided part with 4 prominent fold- like 

 protuberances partly filling the throat; segments of upper Up each deflexed 

 and coiled backward into a ring, the, corolla-tube at base of these seg- 

 ments abruptly raised into a sharp protuberance. Plains of the lower 

 Sacramento, especially about Elmira. May. 



# * * Segments of corolla not very dissimilar. 



6. B. humilis, Greene. Very dwarf, the stem branching, only about 

 1 in. high: segments of the calyx-limb linear, unequal, exceeding the 

 minute while corolla; this bilabiate, the upper segments being smaller, 

 but all of them ovate-oblong, acute. Moist plains of Sonoma Co.

 stamens quite distinct. Style I, with 2 5 introrse stigmas. Flowers in 

 all oars blue, or bluish.

1. CAMPANULA, Dodoeus. Flowers all complete. Calyx-lobes 5,
