310 ICOSANDIUA POLYGYNIA 



Root creeping. Stem 3 to 5 feet high, suftruticosc, branched, not prickly, hul 

 clothed with a rou^hish glandular viscid pubescence. Leaves -1 LO 8 Inches long, 

 and nearly as wide as long, simple, of a lively green color, mostly 5*lobetf, Cordate 

 at base, more or less pilose, hirsute on the nerves beneath ; lubes palmately 

 spreading, acuminate, unequally serrate, serratures acuminate \ petioles 2 to 1 ur 

 6 inches long, glandular-hirsute; stipules lance-linear, acuminate, scarcely adnatc 

 to the petiole, deciduous. Corymbs compound, clothed with a purplish clammy 

 glandular pubescence ; pedicels with linear-lanceolate acuminate bracts at base. 

 Calyx glandular-hispid ; seg7nents ovate, with a long acumination which is some- 

 times foliaceous. Petals mostly bright purple, sometimes palish, oval, or roundish. 

 oval, large. Stamens very numerous, whitish. Fruit broad, hemispheric, con- 

 cave beneath, on a largo receptacle, bright rod when mature (yellow, Pursh, 

 honey-yellow, 7brr.)j succulent, but scanty or thinish, well-flavored. 

 Hab. Rocky hills; Brandy wine : rare. Fl. June— July. Fr. July— Aug. 



Obs. This differs widely, in habit, from any of the preceding; but ihv fruit is 

 decidedly that of the Raspberry, or Thimble-berry. It is an ornamental plant, and 

 often introduced into flower-gardens. The plant rarely j>erfect8 its fruit, under 

 cultivation;— and, indeed, it is frequently abortive in its native localities. I have 

 seen it on the mountains,, in full bloom, and with ripe fruit, at the same time; 

 and, as far as I have observed, the fruit is always bright red, or scarlet. It is 

 very rare in this County,— having only been found, as yet, on the rocky banks of the 

 Brandywine, above Coatesville,— where it was detected by Mr. Joshua Hooi»bs, 

 in 1833. Eifiht or ten additional species are given as natives of the United States ; 

 and Prof. Hooker enumerates 21 species in British America.

 [Supposed to be from the Celtic, Rhos, red ; the prevailing color of the flowers.] 



Calyx with the tube urccolate, contracted at the orifice ; limb 5-partcd; 

 segments, before they expand, somewhat spirally imbricated at apex, 

 mostly with a foliaceous appendage. Petals 5. Carpels numerous, 

 bony, hispid, included in and attached to the tube of the calyx, which 

 becomes fl -hy and berry-like. 



Fruticose: mostly aculeate ; leaves alternate, mostly odd-pinnate, stipular ; sti- 

 pules adnate to the petiole ; leaflets serrate ; flowers terminal, solitary, or sub-co- 

 rymbose. Nat. Ord. 73. Lindl. Rosacea.

 often aculeate, winged at base by the adnate stipules; stipules linear, the apex 

 free, or produced, diverging, lanceolate, acuminate, with a pair of straight ruckles 

 at base, or often none. Leaflets 5 to 9 (mostly 7), 1 to near 2 inches 1qp*> and half
