THE STRUCTURE OF CERTAIN NEW HYBRIDS. 173 
It is interesting to find that in Mr. Culverwell’s hybrid short-stalked 
glands occur on the ovary and on the lower part of the calycine cup 
also. They are never quite sessile, and are large enough to be easily 
seen by the aid of a hand lens. Their stalks are relatively delicate, and 
vary in length from ‘03mm. to 06mm. The diameter of the gland is 
commonly from ‘1 mm.to’12 mm. Very often the glands are bright red, but 
commonly enough they are colourless. At least as many as twenty-four 
red glands may be found in one flower, besides numerous colourless ones. 
All gradational stages, from the claret-coloured to the colourless, occur. 
Sometimes the coloured ones are found on one side of the ovary, and the 
colourless ones on the other. I have not noticed any sessile yellow 
glands, and I am therefore unable to corroborate Dr. Macfarlane’s state- 
ment (loc. cit. p. 281) that “four types’”’ of ‘“ hairs,’ including sessile 
glands, are present on the ovarian surface of this hybrid. 
The bright-red coloured glands, above described, may with consider- 
able assurance be regarded as identical in structure and function with 
those in the Gooseberry, and there seems no good reason to suppose that 
the absence of colour in the others constitutes a material difference.

Stalked glands of the same size as those in Mr. Culverwell’s hybrid, and 
occupying a similar position, occur in the flowers of my two hybrids 
(fig. 84). The diameter of the glands is ‘1mm. to’13mm., and the length 
of stalk ‘03 mm. to'13 mm. _ I have, however, never seen any of them 
red-coloured; and I am accordingly inclined to believe that a variety 
of Gooseberry with little or no colour in the glands may have been the 
parent of my plants. 
If the bisected flowers of my hybrids and their parents be compared 
(figs. 86, 87, 88), many features showing a blending of the parental 
characters will be observable. The ovary is nearly intermediate in size. 
The style arises from an almost flat surface in the Gooseberry, and from 
a greatly arched surface in the Black Currant. It is raised on a slight 
elevation in the hybrids. 
The style in the Black Currant (fig. 86) is solid and glabrous, and 
the stigma inconspicuously bifid. In the Gooseberry (fig. 88) the style 
is cleft almost to the base, and is clothed with hairs which radiate 
horizontally, the longest being at the level of the throat of the flower. 
In the hybrids (fig. 87) the style is cleft nearly midway, and bears hairs 
which are much fewer in number and shorter than those of the cor- 
responding organ of the Gooseberry.
