Darwin Correspondence Project

From Lydia Ernestine Becker   18 May 1863

Miss Becker presents her compliments to Mr. Darwin and takes the liberty of sending him the enclosed flowers of a variety of Lychnis dioica common in the woods here but which she has not observed elsewhere.1 It has bisexual flowers and large dark purple anthers which give the plant a very striking handsome appearance. The same conspicuous anthers occur in flowers bearing stamens only of which one is sent. Miss Becker does not know whether such a variety as this would be interesting to Mr. Darwin, if not she must apologise for having troubled him.

Becker lived in Altham, Lancashire, between 1838 and 1865, during which time she developed an interest in botany (DNB). It was later established that these plants represented a diseased form of Lychnis dioica (Silene dioica) and not a new variety (see letter from L. E. Becker, 23–4 May [1863] and CD note, letter from L. E. Becker, 28 May [1863], and Becker 1869). When Becker published her observations she substituted the name L. diurna, a synonym for L. dioica (Index Kewensis).
