To Friedrich Ludwig   1 August 1877

Down Beckenham Kent

Aug 1. 1877

Dear Sir,

I am very much obliged to you for your clear account of the cleistogamic flowers of Collomia, together with the dried flowers.1 The case seems to me a very striking and interesting one.

I remain, dear Sir, | Yours faithfully & obliged | Charles Darwin

Ludwig had sent CD his description of cleistogamic flowers of Collomia grandiflora (large-flowered mountain trumpet or phlox) from the Verhandlungen des botanischen Vereins für die Provinz Brandenburg (Ludwig 1876). CD’s annotated copy of Ludwig’s description is in DAR 133.19: 6. CD added a reference to Ludwig 1876 in the preface to Forms of flowers 2d ed., p. x.
