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.

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
Yours very sincerely | C. Darwin
