    Thanks for Oxalis. Only experimentation will show whether disproportion of long- to short-styled flowers is a functional dimorphism.

    Case of aestival flowers is very curious.


Down. | Bromley. | Kent. | S.E.

April. 24th

Dear Oliver.

Many thanks for Oxalis; of 38 flowers sent 24 are long-styled & 14 short-styled, just as in the flowers here; but whether this depends on mere useless variability or on useful dimorphism, I suspect experiment will alone show: I have got plants in pots for next spring.

I am quite aware the other æstival flower is a very much more curious case. I return 6d stamp which I suppose is a Kew affair.—

Yours very sincerely | C. Darwin
