From J. D. Hooker   18 December 1876

Dear Darwin

Forsythia has never fruited at Kew but has copiously at the Hort. Soc. Gardens   I do not know which species—. I have referred to two figures of F. viridissima, both have very short stamens & a long style*— also to one of F. suspensa— it has long stamens & a very short style.

*one of these is taken from a plant in Hort. Soc. Gardens¹
