76 MONADEIPHIA. rBNTANDRIA. 



and therefore importantly specific. 3. crassinecula. Krect.. 

 subpubescent; stem mostly simple; leaves linear-lanceolatej 

 serrulate, acute, and rather thick; flowers subsessile; seg- 

 ments of the calix reflexly denticulate; disk of the lower 

 lip of the corolla bearded. — Flowers very few and remote,, 

 rather large, blue, calix as often sniootli as pubescent. 4. 

 amana. Obs. 'Jhe largest of the United States' species. 

 Leaves more commonly scabrous than smooth, lanceolate 

 acuminate, serrate, 6 to 8 inches long, little more than an 

 inch broad; flowers bright blue m st curid racemes. 5.pu- 

 berula. Erect, simple and pubescent; leaves subelliptic, 

 or elliptlc-m-ate, serrulate; spike secund, foliaceous at the 

 base, bractes serrulate; calix shorter than the tube of the 

 corolla; segments of the lower hp oval, acute. — Very near- 

 ly allied to L. Clayioniana, but the flowers are 3 times as 

 large, and of finer and deeper blue. The calix is either 

 smooth or pubescent, never ciliated. Hab. On the mar- 

 gins of ponds and swamps in the Fine forests of Carolina 

 and Georgia. 



6. *Micha-uxri. L. Cliffortiana. Mich. Rather smooth, 

 brancbiHg above; leaves petiolate, oval, crenately toothed; 

 lower ones suborbicular; spike leafless; flowers small, 

 pedicellate. Hab. In Virginia. Certainly distinct from 

 L. Clijortiaiia of Linnseus, which appears' to be a South 

 American species. 7. Cknjtoniana. Obs. Bractes entiie, 

 calix equal with the tube of the corolla, segments of the 

 lower lip oblong, palate prominently bidentate as in L. pu- 

 benila; sjiike smooth, naked beiov,-. 



7. Kalmii. Siem smooth, erect and branching; leaves 

 smooth, long, linear and nearl\ entire; raceme loose and 

 leafy; peduncle longer than the' fruit, mir.utely bibracteate 

 at the summit; calix campanulate, segments lanceolate, 

 shorter than the capsule, which is attenuated at the base. 

 Hae. In the state of New York, &c. 1 have scarcely seen 

 any plant, the flower apart, which so imposingly resembled 

 Campanula rotundifolia. It is one of the slenderest and 

 most northern species; tlie cailx including the germ (which 

 it properly invests throughout this genus) is peifectly 

 campanulale; in the specimen before me, which appears 

 luxuriant and virgately branched, some of ^he leaves are 

 2 1-2 inches long, and scarcely 2 lines wide, with here and 

 there a minute denticulation; the fruifmg peduncles are 

 an inch in length, with the very minute and almost glan- 

 duliform bractes occupying a position on the peduncle not 

 to be met with in any other of the species in this Cata- 

 logue; the capsule smooth, and partly vesicular, is obovate 

 and acute below as in a Campanula! the flower is of a 

 delicate blue, the segments of the lower lip oboval and
