1160. Lav. 13. G.W. 14, pp. 562-3. R.H. 1856:341. Here also 

 belongs probably C. divaricdta, Jacq., with short-petioled pinnate 

 Ivs. and blue, less spreading sepals. 



2. Fremontii, Wats. Fig. 981. Closely allied to C- 

 ochroleuca, but with Ivs. 3-4 in. long, nearly sessile, 

 either entire or with a few coarse teeth: fls. often 

 drooping; sepals thick, purple, nearly glabrous, except 

 the tomentose edges; styles when young downy rather 

 than feathery. July, Aug. Mo. to Colo. G.F. 3:381 

 (adapted in Fig. 981). G.W. 14, p. 563. 



3. ochrole&ca, Ait. Herbaceous, 1-2 ft. high, silky- 

 pubescent, becoming glabrate: Ivs. ovate, entire: fls. 

 erect, solitary, terminal; sepals yellow outside, cream- 

 colored within; styles becoming somewhat plumose. 

 July, Aug. Dry grounds, N. Y. to Ga. L.B.C. 7:661. 

 Intro. 1883. 



4. Douglasii, Hook. Has habit of C. integrifolia, 

 about 2 ft. high: st. and petioles angled and ribbed: 

 Ivs. twice pinnately or ternately compound; Ifts. nar- 

 row-linear or lanceolate: fls. tubular or bell-shaped, 1 

 in. long; sepals recurved, deep purple within, paler 

 without. June. In mts., Mont, to New Mex. Intro. 

 1881. Var. Sc6ttii, Coulter, has the Ifts. ovate- or ob- 

 long-lanceolate. A hybrid of C. Douglasii var. Scoltii x 

 C. texensis is C. globuldsa, Hort., with deep purple 

 pitcher-shaped fls. Gn. 75, p. 472. 



5. aromatica, Lenne & C. Koch (C. cserulea var. 

 odprata, Hort.). Slender, herbaceous or somewhat 

 climbing, reaching 6 ft. high if supported: lys. of 3-7 

 ovate, nearly entire Ifts.: fls. solitary, terminal, very 

 fragrant, lJ^-2 in. across; sepals 4, spreading, reflexed, 

 reddish violet; stamens white. July-Sept. Nativity, 

 perhaps S. France. It is thought by some to be an old 

 garden hybrid, probably C. Flammula x C. integrifolia.

6. crispa, Linn. A slender climber, reaching 3-4 ft.: 

 Ivs. very thin; Ifts. 3-5 or more, variable in outline and

 34:147. V. 6:379. Lav. 14. This and the allied 

 species are fragrant. A hybrid of this species is C. 

 cylindrica, Sims (x C. integrifolia). See No. 1. A number 

 of hybrid forms, the offspring of a cross between this 

 species and C. texensis are figured and described in 

 M.D.G. 1898:500 and one as "blue bells" in Gn. 49, 

 p. 189. 



7. Simsii, Sweet (C. Pitcheri, Torr. & Gray). High

 of its beautiful fls. Some of the garden hybrids of this 

 species, which have been classed under C. pseudo- 

 cocdnea, Schneid. (x C. Jackmanii), are found under 

 the names: Countess of Onslow, deep scarlet. Gn. 57,
