430 ADDITIONAL NOTES, ETC. 



in the first volume, however, the distribution is probably 

 that of R. csesius more or less mingled with other forms 

 now separated ; and doubtless many botanists will prefer 

 the more exact, though less full, sketch by Mr. Babing- 

 ton, in this current volume, page 346. 



346. Bitbus Idceus, vol. i. p. 354. 



The south Hmit is extended into Cornwall, on authority 

 of Mr. Pascoe. I presume that my idea of E. Idseus in- 

 cludes also the E. Leesii of Babington, which is unknown 

 to me. The production of flowers and fruit at the tops of 

 the current year's suckers, is rather frequent among gar- 

 den raspberries, but is quite inconstant from year to year 

 on the same root. The prickles, too, are very variable in 

 the garden raspberries ; and though I have never actually 

 ascei-tained the fact by exact experiment, I entertain no 

 doubt that the prickles '"' setaceous from a bulbous base," 

 supposed to be a diagnosis for E. Leesii, might be pro- 

 duced from fruits of E. Idaeus. An individual botanist 

 who, Hke myself, takes much and active interest in prac- 

 tical gardening, will often reach conclusions about the ex- 

 tent of species-variation, very different from the infer- 

 ences obtained by botanists of the herbarium, whose 

 means of judging are restricted to the outside characters 

 of shape and proportion, unaided by observations on 

 the physiological facts of growth and descent, as varied 

 by age, season, soil, humidity, &c.

 (E. vUlosa, &c.). 



The general sketch of distribution for a species, or ag- 

 gregate species, under this name, may be understood to 

 take in the various forms which British botanists label un- 

 der the names of mollis, villosa, tomentosa, scabriuscula, 

 gracilis, Sabini, Doniana ; perhaps, also of WUsoni and
