My dear Dyer

I am going again to beg assistance of you. & Kew. We badly want apheliotropic plants & think we see our way to good results if we had more plants to work on. We want young plant of Smilax aspera, & rather want Mutisia clematis & Eccremocarpus, but seeds of 2 latter would do.² We also want any of following seeds, (on account of their radicles) which you may chance to possess, & which Thompson of Ipswich³ has not.— I copy all out on following page.⁴ The 2 plants of Bignonia capreolata, which you sent have been invaluable & shall herewith be returned.⁵

Yours very sincerely | Ch. Darwin

P.S. I forgot my most important question. I can get seeds of Viscum, but how w^d be best manner of making seeds germinate, so that they c^d. be observed & Dutrochet says hypocotyls strongly apheliotropic.⁶
