in minor points in leaf and flower. Spines are entirely absent in Mr. 
Burnett’s, Mr. Culverwell’s, and my own hybrids. « 
In comparing the hybrids with their parents it has to be kept in mind 
that, while there is but little structural difference in varieties of Black 
Currant, much more exists in varieties of Gooseberry, both in flower 
and foliage. As already stated I cannot now identify the Gooseberry 
parent of my hybrids, and I am accordingly unable to make definite 
statements as to the origin of peculiarities exhibited by them. 
While the size and the shade of colour of Gooseberry leaves may vary, 
the form is almost always the same, a marked characteristic being the 
non-cordate base. In Mr. Culverwell’s plant there is a closer approach 
in leaf form to the Gooseberry than obtains in my plants, the leaves of 
the latter (A, fig. 81; C, fig. 82) being more distinctly cordate. No Black

Leaves (nat. size). 
Currant odour is emitted when the leaves of my hybrids are bruised, and, 
as in Mr. Culverwell’s case, the Gooseberry caterpillar finds them specially 
palatable. 
A few irregularly scattered, colourless, stalked glands are found on the 
under side of the leaves of my plants and Mr. Culverwell’s also. The 
head is multicellular, much flattened, ‘1 mm. in diameter, and the stalk 
is very short, and is not more than ‘03 mm. in diameter. It seems certain 
that these glands disappear for the most part as the leaf attains maturity. 
No quite sessile ones, reproducing the form of those in the Black Currant, 
were met with. lam accordingly led to dissent from Dr. Macfarlane’s 
opinion (loc. cit. p. 274) that any reproduction of the sessile glands of 
Fi. mgrum is found to occur in the hybrid.
