Mr. Woods on the British Species of Rosa. 221 



cumstances induce me to believe that Jacquin would have in- 

 cluded in his species most, if not all, of those different ap- 

 pearances which I have united into mine. The glandular foot- 

 stalk varies in R. bractcsccns, R. canina, and other neighbouring 

 species ; which will justify us in rejecting it from the essential 

 character in this instance,^ though a most diligent search has not 

 succeeded in bringing to light a single instance of glands or setffi 

 on the peduncle of any variety a native of this country : — once, 

 indeed, on one plant I found a few hairs on that of tlie variety y. 



'I'his last-mentioned variety is certainly a very different plant in 

 appearance from either a, or )8, and may perhaps be a distinct spe- 

 cies; bull have found myself unable to find any character by which 

 it might be separated ; and it besides varies greatly in, itself both 

 in habit and in character. The leaflet* are sometimes almost as 

 broad, but I believe never as flat, as those of R. Rorrevi and R.du- 

 metorum; and the calyx-seginents sometimes approach in shape 

 and number to those of these plants; the serratures too, though 

 never double, become sometimes exceedingly unequal. At other. 

 times the long leaflets and equal serratures might lead one, with- 

 out the inflorescence, to refer it to R. sy^yla. To this variety I 

 should refer the Rose Avhich is mentioned by Afzelius as a hairy 

 variety of R. canina, and quoted by Sir J. E.Smith under R. casta: 

 some further observations on Afzelius's varieties of R. canina will 

 be found in the account of that species. The glandular fringe of 

 the serratures sometimes passes into hairs. 



Of the variety 3 I have only seen one plant, and that before it& 

 flowers were open : it was a compact bush, between three and. 

 four feet high, abounding in flower-buds ; and the numerous 

 small and very acute leaflets gave it a peculiar appearance.
