Conclusions Bardfield Oxlips

often happens with primula is is difficult to value the degree of sterility. But the sterility of these illegitimate unions is clearly shown by the small percentage of pods produced. I

(Both forms spont. produced a very few pods, some with no seed, & 6 with seed had on average only 7.8 seed.

(Eight flowers, long-styled, were legitimately fert. by short-styled common oxlip & gave only one pod with 4 seed, & these might have been produced by self-fertilisation for the flowers were not castrated.

[9v]

8 flowers of common long-styled Primrose were fert by pollen of long-styled Bardfield oxlip & yielded only 1 pod with 25 seed, & as plant was not carefully castrated this might possibly have been effect of own long-styled pollen

Now in paper on oxlips it has been shown that 8 fl. of long-styled common Primrose fertilise by pollen of long-styled common oxlip yielded 8 pods. (max. 22, minimum 7) with average of 12.7 seed, so that great difference between the 2 kinds of oxlips in this cross— nor is this odd as common oxlip a hybrid from Primrose.
