ICOSANDIIIA— POLYGYNIA. Rosa. 393 



mid-rib especially very hairy. Footstalks hairy or downy, prickly, 

 as well as obscurely glandular. Stipulas oblong, pointed, fringed 

 in the upper part with glands j a little hairy externally ; the 

 upper ones changed for large, ovate, nearly smootli, pointed 

 bracteas, longer than the smoolbjlower-stalks, which are usually 

 2 or 3 together. Tube of the calyx elliptical, quite smooth ; some- 

 times nearly globular ; segments of the limb externally roughish, 

 but not glandular, irregularly, sometimes doubly, pinnate, with 

 smooth, lanceolate, brown-tipped leaflets or subdivisions. Pe- 

 tals flattish, pale red ; sometimes white. Floral receptacle con- 

 vex. Shjles but slightly hairy, distinct, and not very prominent. 

 Stigmas in a round lax head, smooth. Fruit elliptical, occa- 

 sionally nearly globular. 



I do not perceive any remarkable difference between Mr. Woods's 

 collina /3 and y ; the latter is said to be common all around Lon- 

 don, and indeed throughout England. His a, or sup!)osed type 

 of the species, is R. collina, Jacq. Justr. t. 197, which, by a spe- 

 cimen from the author, appears distinctly characterized by its 

 dense habit, hy'\.?,\\y flower-stalks, very hairy styles, and rounded 

 leaflets. This latter has not been gathered in Britain. Finding 

 myself obliged to separate it from the plant Mr. Woods has de- 

 scribed, I gladly concur with Mr. Sabine in giving Mr. Forster's 

 name to what thus becomes a new species, totally different in 

 the simple and naked, not glandular, serratures of its leaves 

 from all the preceding, principally R. Borreri, which it other- 

 wise resembles ; and from R. canina in its hairy mid-rib. 

 Whether any other characters may be discovered betwixt R. For- 

 steri and canina, on a comparison of living specimens, must 

 for the present be left in doubt ; for there are many particulars, 

 concerning several of our most common Roses, that still re- 

 quire investigation. 



Of Mr. Woods's S, an elegant little plant, with small pointed 

 leaflets, I have only^een one dried specimen, which answers to 

 the above specific character. 



19. R. hibernica. Irish Rose. 



Fruit nearly globular, smooth, as well as the flower-stalks. 

 Calyx pinnate, with entire appendages, permanent. 

 Prickles slightly curved, scattered, unequal. Leaflets 

 simply sci'rated, elliptical ; ribs hairy beneath.

Discovered in the counties of Derry and Down, particularly near 

 Belfast harbour, by Mr. Templeton, who, in consequence of 

 its being judged a new Irish plant, received from a society at 

 Dublin, " cxemplo rare et inaudito," a premium of 50 pounds
