54 DICOTYLEDONOUS PLANTS. 



4. C. arvciisc Linn. : stems ascending ; leaves linear-lanceolate, ob- 

 tuse, more or less hairy, especially at base ; flowers few, terminal ; 

 peduncles deflexed, pubescent ; petals twice as long as the calyx ; cap- 

 sule oblong-cylindrical, scarcely longer than the calyx. 



HAH. Fields and rocky hills. N. S. May Aug. It. Root 

 creeping. Stems 4 b inches long, ascending, slender, some- 

 what cespilose. Leaves crowded at the base of the stem, short, 

 ciliate at base. Flowers large, white, 2 or 3 on terminal pedicels. 

 Petals deeply cleft, white, twice as long as the calyx. This is 

 undoubtedly a native near Albany, as it would seem to be also, 

 according to Dr. Barton, on the banks of the Schuylkill and De- 

 laware. Fl. Phil. i. 216. Dr. Bigelow credits it to the vicinity 

 of Boston, but thinks it merely naturalized. Field Chickwecd. 



5. C. tenuifvlium Pursh. : pubescent- cespitose ; leaves narrow-linear, 

 longer than the inter nodes ; flowers on long peduncles, mostly 3, from 

 the top of each stem ; petals obovate, emarginate, thrice as long as the 

 acute calyx. C. dicltotomum Muhl. ? 



HAB. Rocky places. N. S. June. 2_. Stems numerous, erect. 

 Flowers on long peduncles, 3 from the summit of each stem. Re- 

 r.ombles the preceding, but has longer and narrower leaves, and 

 longer and less deeply cleft petals. But it may, after all, be a 

 mere variety. Sprengel considers C. pennsylvanicum of Horne- 

 inann identical with it. 



6. C. pubcsccns Goldie: pubescent-hirsute; stem deflexed-pilose ; 

 leaves linear-lanceolate, longer than the internodes ; panicle terminal, 

 about 3 C-flo\vered ; petals acutely emarginate, twice as long as the 

 calyx. 



* HAB. Kingston, U. Can. Bellows' Falls, N. H. June. Lf. 

 This species was first described by Mr. Goldie. K<Hn. /'////. 

 Jour. vi. 327. I have specimens of the same plant collected at 

 Bellows' Falls, by Mr. G. W. Clinton, They resemble those of 

 the preceding species, but the stems are much longer and more 

 slender, and are branched from below in a dichotomous manner ; 

 the peduncles also, are much longer, and the flowers more nu- 

 merous : the sepals have a white shining and scarious margin. 



7. C. nutans Rqf. ; viscid and pubescent ; stems erect, straight, 

 deeply etriate ; leaves elongated, distant, lancsolate-linear ; flowers 

 subumbellcd, on long petioles ; petals oblong, bifid at the tip, longer 

 than the calyx ; capsule nodding, twice as long as the calyx. C. gliOi- 

 nosum Nvtt. C. longe pcdunculatum Muhl. 



HAB. Rocky hills. N. S. June. . Stems numerous, 8 12 

 inches high, very viscid. Lower leaves subspathulate. Flowers 

 terminal, in a loose dichotomous panicle. 



8. C. oblongifolium Torr. : cespitose, pubescent ; stems erect, terete, 

 even ; leaves lanceolate-oblong, rather acute, shorter than the joints ; 

 flowers terminal, shorter than their pedicels ; petals obovate, bifid at 

 the tip, twice the length of the calyx. C. bracteatum Raf. ? 



HAB. Mountains. Mass. June. 14-. Stems 8 10 inches high.
