Trifolium repens A

Fig 153.

[fig] B

Same scale.

These 2 figures to be on same block, with the dots (when I have put red dots) on a level, for the whole is one tracing.

In ones to put the blocks side by side within the my page, some of the lettering will have to stand vertical, I think.

Two 2 sets of lettering in A, 10 sets of lettering, but mostly short ones in B. The two figures will just go in Page.

N.B The description (see back) can stand in the corner by cutting away Block.

This plant like the Linaria is almost sterile if insects are excluded, and we may draw the same inference as before, namely that the parent-plants must had been intercrossed during every or almost every previous generation. Nevertheless the self-fertilised seedlings were plainly inferior in height and vigour to the crossed.

My attention was now thoroughly aroused, for I could hardly doubt that the difference between the two beds was due to the one set being the offspring of crossed, and the other of self-fertilised flowers. Accordingly I selected almost by hazard two other plants, which happened to be in flowers in the greenhouse, namely Mimulus
