CALYCANDRTA. POLYGYNIA. 65 



B. FLAGELLAras. Ph. Procumbent; leavesternate; middle one cuneale at base; flowers terminal. 



Fl. Latter end of May. Fr. mat. Latter end of JTuly. 



ffab- Woodlands; and along shaded rivulets; frequent. 2 to 4 feet long: flowers white; fruit black. 



Obf. This is made a variety of the foregoing, by some botanists; but it seems to be pretty distinct. The 

 T7hole plant is more delicate, and rather more glabrous. The ripe berries, as remarked by Dr. W P C 

 Barton, are rarely perfect— a few only of the acines arriving at maturity. It is possible, however, that 

 all thisdiflference may re.sult fioin its growing in the woods— where I have most commonly observed it. 



H. OBovALis.!' Ph. Procumbent; stem very hispid; leaves tcrnate, obovate, ovate, and rhomboidal. 



Fl. Latter end of May. Fr. jnat. 



ffab. Woodlands: Barrens, above S. Stringfellow's: not common. 2 to 4 feet long: flowers white. 



Obs. I was inclined to refer this to the R. hispidus, of Willd. and Pursh; but Mr. Schweinit?, to whom 

 Isubmitted my specimen, supposed it to be II. obovalis. Perhaps they are really not distinct. 



{)Cf= The R. oDORATUs, I have not found giowing native in this vicinity; but Dr. Bajdwin informed 

 He he had seen it on the Brandy wine, near the factories of the Messrs- Dupontfi. 



216'. GEUM. Nutt. Gen. 448. 

 [Gr. gaio, to be splendid; or gcwo, to relish, ar give a good taste; from its appearance, or properties.] 



Cal- inferior, 10 cleft, alternate segments smaller. Cor. petals 5. Seeds awned; awns mostly geniculate. 



G. ALBLTM. Ell. Radical leaves pinnate; cauline 3 lobcd; stipules incised; petals as long as the calyx. 

 Vulgo — Avens. Herb Bennet (a corruption of the French, herb" benite). 

 Fl. Beginning of July. Fr. mat. Latter end of September- 



Hab. Rich Woodlands; thickets, &,c- frequent. About two feet high: flowers white. 

 Obs. The three-lobed stem-leares considerably resemble those of the currant bush. 



G viRGiKiANUM.^ £//. Radical and lower leaves ternate, upper lanceolate; petals shorter than the calyx. 

 Fl. Middle of June, and after. Fr. mat. Beginning of September, and after. 



Hab. Roadsides; fence-rows, &c. frequent. 2 to 3 feet high: flov.'ers white, or yelloiv. 



Obs. Some of my specimens are quite hirsute,— the radical leaves often quinate— the flowers small, and 

 yelloif: nossibly only varieties. 



fK' T have otht^r specimens, (both hirsute, and nearly glabrous,) with the leaves all ternate, except the 

 sm'ili upper ones.- the yietals as long as the calyx, and white. Mr. Schweinitz, who examined them, be- 

 Jiev-sthem to be "a n^w species, not a« all described," which "might .tustly be called G- ternatitm.'/ 

 They seem to be intermediate between the two foregoing; but not suiting the descriptions of either. 



217. POTENTILLA. Natt. Gen. 449. 

 [Lat. Potentia, power; from its imaginary medical powers.] 

 Cai.. inferior, 10 cleft, spreading. Cor. petals 5. Seeds roundi^^h, naked, attached to a dry receptacle. 



P. N-onwEGiCA. Ell. Hirsute; erect; dichotomously branching; leaves ternate; peduncles axillary. 

 Ft. Latter end of July, and after. Fr. mat. Middle of September, and after. 



Hab. Pasture fields; along Brandywine: frequent. About two feet high: flowers yeliow. 



06s. I should judge this to be a stranger here. It may have strayed hither from Canada,— where Will- 

 denow says it is a native. 



p. CANADENSIS. Ell. prccumbent; silky; leaves quinate, cun-^ate-obovate, incised-dentale. 

 Vulgo — Common Cinque-foil. 



Fl. Last of April, and after. Fr. mat. Beginning of June, and after. 



Jfab. Old fields; and sterile pastures: very comnjon. 6 to 12 inches long: flowers yellow.

 Fl. Middle of May, and after. Fr. mat. Last of June, and after. 



Hab. Woodlands; roadsides, &c. common- 9 to 15 inches high: flowers yellow. 



06s. This spe_cies, when it first flowers, is usually about a foot high; but it often extends, afterwards, to 

 .:^ or 3 tect, and becomes almost procumbent. 



213. FRAGARIA. Nutt. Gen. 431. 

 [Lat. fragrans, smelling sweetly; in reference to its fragrant fruit.] 



Cal- inferior, 10 cleft. Cor. petals 5. Receptacle of the seed ovate, berried, deciduous.

liab Neglected old fields; fence-rows, &c. frequent- 6 to 12 inches long: flowers white; fruit red. 



0;V?. Improved agriculture, and ihe rotation r.f crops, have cuused thi* Jcliciouif.'ujt to be more rare it!
