D. bicornuta. Most like D. pulchella, more ascending or erect, short-leaved: corolla 

 intensely blue with white centre ; lip witli short lobes, and a strong constriction above the 

 auricnlate base, the face of which bears a pair of conspicuous conical hollow appendages.

CAMPANULACE^E. 



2. G-ITH6PSIS, Nutt. P. 10, add: 



Gr. diffusa, GRAY. Slender and diffusely much branched, small-leaved, glabrous and 

 smooth : calyx-lobes subulate-lanceolate from a broad base, about equalling the small corolla 

 and half the length of the linear closely sessile capsule : seeds short-oblong. Proc. Am. 

 Acad. xvii. 221. Cucamouga Mountain, San Bernardino Co., California, Parish. 



4. CAMPANULA, Tourn. After C. un\ 'flora, p. 12, add : - 



C. SCabrella, ENGELM. Cinereous-puberulent or minutely scabrous to nearly or quite gla- 

 brous : numerous stems from the multicipital caudex 2 to 5 inches high ; larger ones 

 2-4-flowered : leaves thickish ; radical spatulate, upper cauline linear : flowers more erect 

 and rather larger than in C. uniflora : lobes of corolla ovate-lanceolate, as long as its cam- 

 pauulate tube: capsule oblong-turbinate, not narrowed at summit. Bot. Gazette, vi. 237. 

 Higher mountains of N. California and Washington Terr., Engelmann (1880), Pringle, Suks- 

 dorf, Howell, Brandegee. 



C. Parryi. A span to a foot high from elongated and creeping filiform rootstocks, mainly 

 smooth and glabrous : stem slender, erect, simple and with slender-peduncled flower, or with 

 some lateral leafy branches : leaves thinuish, entire or sparingly callous-denticulate, some- 

 what veiny ; radical and lower spatulate or lanceolate with tapering base hirsute-ciliate ; 

 upper linear-lanceolate from a sessile base, attenuate-acute : flower erect in anthesis : corolla 

 almost crateriform, 5-lobed to middle, spreading to a full inch in diameter, violet-blue or even 

 purplish, little surpassing the linear-subulate often callous-denticulate calyx-lobes : ovary 

 turbinate: capsule nearly obovate, opening close under the base of the erect calyx-lobes.

 Syn. Fl. ed. 1, excl. var., not Vill. C. plan (flora, Engelm. in Bot. Gazette, vii. 5, not Lam. 

 Mountains of Colorado, especially southward, subalpine and along lower streams, common, 

 first coll. by Parry, then by Hall & Harbour. Also S. Utah mountains, Siler, and near 

 Fort Wingate, New Mexico, Matthews. 



C. PLANIFLORA, Lam., on p. 14, a species long ago in cultivation, was wrongly guessed to be 

 American. It is very near C. pi/ramidalis, L., of S. E. Europe, perhaps a variety of it. 



C. rotundifolia, L. To this polymorphous species refer all the forms assembled under 

 " C. Scheuchzeri" (not Vill.), excepting what belongs to C. Parryi, and (to avoid the ques- 

 tion as to what is truly C. linifolia, Lam., and C. Scheuchzeri, Vill.) adopt the nomenclature 

 of Lange, viz. : 



Var. arctica, Lange, Fl. Dan. xvi. 8, t. 7211 (C. linifolia, var. Langsdorffiana, A. DC., 

 and probably his C. dubia and C. pratensis, also C. rotundifolia, var. linifolia, Gray, Man. ed. 2, 

 244, not Wahl. Fl. Lapp.), for the more rigid and one-few-flowered form, with corolla 

 usually inch long, and very slender calyx-lobes soon spreading or deflexed. Common from 

 Canada and Labrador to the arctic regions. 



Var. Alaskana. Leafy to the top: radical leaves cordate; lowest cauline ovate, the 

 succeeding ovate-lanceolate to lanceolate, nearly all petiolate : calyx-lobes attenuate, soon 

 deflexed : corolla an inch to nearly an inch and a half long. C. heterodoxa, Bong. Veg. Sitk. 

 144, not of Vest, by the character. C. linifolia, var. heterodoxa, Ledeb., and C. Scheuchzeri,
