THE STRUCTURE OF CERTAIN NEW HYBRIDS. 169 
Dr. Macfarlane (without fruit), as the most distinctly intermediate. Mr. 
Culverwell, in Gardeners’ Chronicle, vol. xii. p. 346, mentions that this 
plant possesses ‘‘not a particle of scent like the Black Currant,” and, 
further, that “the Gooseberry caterpillar is particularly fond of the 
hybrid, whereas it will not touch the Black Currant.” 
Five years ago I succeeded at St. Andrews in repeating the same 
cross, and my stock consists of three indubitable hybrids. Besides these, 
however, there appeared a number of plants of pure Black Currant; the 
latter vary among themselves a little, but are no doubt the result of 
accidental self-pollination. Such an accident is not altogether easy to 
avoid in experimenting with the Black Currant. I understand that Mr. 
Burnett weeded out some plants from his crossed stock, because he re- 
garded them as Black Currant seedlings ; and the reference made by Mr. 
Fic. 78.-_FLowERING-sHoor or R. nicRuM x R. Grossunarta, B (nat. size). 
Culverwell (above quoted) to two of his seedlings possessing the Black 
Currant odour seems to point to a similar accident having befallen him 
in his experiments, although the incident may now be forgotten. 
I was unfortunately unable to take note of the names of the varieties 
I operated with, or the number of fruits set and seeds sown. The three 
hybrids (A, B, C) proclaim their authenticity unmistakably in the form of 
their foliage. Two of them (A, B) flowered for the first time last year 
(1898) ; the third (C), which has not flowered yet, is not so robust. 
With different treatment they might have been brought into flower at an 
earlier age. The stronger two are not quite similar, the one (A) being of 
taller habit, rather less floriferous, and with flowers rather larger than the 
other (B) (fig. 78). All three bear a marked general resemblance to 
Mr. Culverwell’s best known form, but are distinguishable from it
