Plant clothed with a rough ish pubescence, viscid at summit. Root annual. Stem 

 6 to 12 or 15 inches high, terete, branching,— the branches opposite and axillary, 

 di- or tri-chotomously paniculate at summit. Leaves I to 3 inches long, and 1 fourth 

 of an inch to an inch wide,— the lower ones spatulate, those above varying from 

 spatulate-oblong to lance-linear,— all more or less acute, tapering at base, sessile,, 

 covered with small rough dots. Plowers terminal, on peduncles half an inch to 

 an inch and half long. Calyx about 3 fourths of an inch long, at first oblong, 

 finally vcntricose-elliptic and about half an inch in diameter, with 10 green hairy 

 ribs, and the intervals whitish and membranaceous; teeth 5, subulate and hairy, 

 1 fourth to 1 third the length of the calyx. Petals pale red, or reddish-white. 

 Capsule as long as the calyx, ovoid-elliptic. Seech numerous, roundish-reniform, 

 striate-ribbed, with the ribs obtusely serrulate, or moniliform, of a dingy leaden-

Hab. Cultivated fields; West -Chester : rare. Fl. July— Aug. Fr. Aug— Sept. 



Obs. This foreigner was found by Mr. Joshua Hoopes, August, 1336, growing 

 in considerable quantity among the stubble of a wheat field, adjoining the Boroucrh 

 of West Chester,— where it had probably been introduced with Clover-seed.

Obovate Cerasus. 



A shrub. Stem 4 to G feet high, branching. Leaves 2 to 4 inches long, and 1 to t 

 or 2 and a quarter inches wide, generally obovate, sometimes oblong-oval, acumi- 

 nate, with the apex mucronate, mostly obtuse at base, equally and very sharply ser- 

 rate, the serratures with a siender callous acumination, rather spreading,— the 

 upper surface green and smooth, or slightly pilose on the midrib and nerves, the 

 under surface somewhat glaucous, smooth, except some small tufts of whitish pu- 

 bescence in the axils of the nerves, and occasionally extending along them ; peti- 

 oles half an inch to 3 quarters in length, smooth, mostly with 2 glands near the 

 base of the leaf. Flowers in simple lateral racemes, from the branches of the 

 preceding year; common peduncle 1 to 2 inches long, often bearing 2,or 3 rather 

 small leaves ; racemes 2 or 3 inches long, diverging, and often recurved, smooth; 

 pedicels about 4 lines long. Drupes 4 to 6 lines long, and about 3 lines in diam- 

 eter, ovoid, rather acute, often slightly sulcate on one side, dark red, or purplish, 

 when mature, somewhat astringent and bitter. 

 Hab. Banks of the Brandywinc : not common. Fl. Fr. July— Aug. 



Obs. Found by Mr. Joseph Rinbhart, July, 1836, on the west side of the Bran- 

 dywinc, near the place called "Deborah's rock," below the bridge on the Stras- 

 burgh road. It is clearly distinct from C. virginiana, and Cserotina,— as Drs. 

 Bigelow and Beck have remarked ; and, as the young branches appear to be 

 smooth, I have some doubts whether it be not also distinct from Prunus hirsutus,
