To W. T. Thiselton-Dyer   15 April 1874

My dear Professor Dyer

Many thanks to you & Hooker— The seeds & plants have arrived, & are worth their weight in gold to me.¹

When in London I will certainly try to get some ground-nuts.

yours very sincerely | Ch. Darwin

I had overlooked the little pot with germinating ground nuts.— What a splendid lot of Cassias & Trifoliums. There is nothing so good as observing a lot of species of same genus.— Tamarindus Indicus is the most valuable of all.—²
