To Daniel Oliver 20 [April 1862]1
Hooker says you pass daily some Oxalis acetosella.2 Will you oblige me by gathering a dozen or score of flowers from different plants, & if possible plants growing a little apart.— I find some evidence of dimorphism in the plants here, as in Primula, & much want to see plants from some other station.3 The plant does not grow here within my walking distance.— Would you send me the flowers by Post in a little tin box, with a bit of damp blotting paper.—
Yours very sincerely | C. Darwin
Requests Oxalis acetosella, which he suspects is dimorphic.
