78 DIALYPETALOUS EXOGENS 



. 



erous, in leafy cymes or corymbs at summit. Carpels rugosely ribbed ; style, sub- 

 terminal. 

 Hob. Pastures, and roadsides: frequent. F I. July. Fr. Sept. 



Obs. This coarse and rather homely weed is considered as indige- 

 nous, in the northern States ; but it has the appearance, to me, of 

 an introduced plant, here. 



2. I". Canaclciisis, L. Villous; stem procumbent or ascending, 



producing runners ; leaves quinate-digitate ; leaflets cuneate-obovate, 



incised-dentate. 



Also, P. simplex. MX. $ Fl. Cestr. ed. 2. p. 304. 



CANADIAN POTENTILLA. Cinque-foil. Five-finger. 



Perennial. Stem 2 or 3 to 12 and 18 inches long, slender, somewhat branched, 

 often several from the same root. Radical leaves on petioles 2 to 6 or 8 inches in 

 length ; stem-leaves nearly sessile ; leaflets half an inch to 1 or 2 inches long. P- 

 duncles axillary, 1-flowered, about as long as the leaves. 

 Hob. Old fields; borders of woods, &c.: frequent. Fl. April. Fr. June. 



Obs. The P. simplex, of Authors, with slender ascending stems, 

 and taller growth frequent along the borders of open woodlands, 

 and in clearings is doubtless very properly reduced to a variety of 

 this. The prevalence of the plant, in arable lands, is a pretty sure 

 indication of a thin soil, or of a thriftless farmer, or both ; though 

 some lands, when kept as pasture fields, seem to have an almost 

 incurable tendency to lose the valuable grasses, and to become 

 speedily overrun with Cinque-foil. Lime and manure, however 

 if duly persevered with will work wonders in the poorest soils. 



120. FRAGA V RIA, Tournef. 

 [Latin, fragrans, odorous; in reference to its fragrant fruit.] 

 Flowers nearly as in Potentilla: styles lateral. Akenes minute, 

 scattered superficially on, or imbedded in, the surface of the en- 

 larged ovoid pulpy deciduous receptacle. Perennial hairy herbs : 

 nearly or quite stemless, but producing prostrate runners: leaves 

 trifoliolate ; flowers white, cymose on scapes, often dioicous, or 

 imperfect, under cultivation. 



1. F. > irgilliilua, Ehrh. Akenes imbedded in the deeply pitted 

 receptacle. 



VIRGINIAN FRAGARIA. Wild Strawberry. 



Root (or rhizoma) thickish, with numerous fibres. Runners creeping, or strik- 

 ing root at intervals. Leaves mostly radical ; common petioles 2 to 4 or 6 inches in 

 length; leaflets 1 to 2 inches long, cuneate-obovate, or oval. Cymes on scapes 

 scarcely as tall as the leaves. Receptacle (vulgarly regarded as the fruit) ovoid, 

 nodding, succulent and bright purple when mature. 

 Hob. Neglected old fields; fence-rows, &c.: frequent. Fl. April. Fr. May. 



2. F. VE"SCA, L. Akenes superficially attached to the receptacle. 

 EATABLE FRAGARIA. Garden Strawberry. 



Hob. Gardens, &c. Nat. of Europe. Fl. April. Fr. May. 



Obs. Long and careful culture of this species (which is very 

 nearly allied to the preceding, and said to be truly indigenous) has 

 resulted in numerous fine varieties, differing in the size, color, and 

 flavor of the receptacles ; and has also produced many abortive or
