Sends a sketch of the haricot climbing the shoot of the plum-tree [see 4866].

Hopes to see CD at the [Horticultural] Congress on Wednesday [30 May].

Sends data on movement direction of Wisteria shoots.

Sends blooms of Cytisus purpureus-elongatus.

Examined the Cytisus and forwarded to Caspary. The C. adami case "gets more and more perplexing", asks for report if Cytisus purpureus-elongatus produces any pods.

Has searched scores of purple-fruited nut-trees, but not a nut is to be found. Has heard there are some nearby and will send them as soon as he receives them.

Greatly interested in case of purple nuts but, after seeing TR’s specimens, dares not trust his case. Wishes he lived near TR or were strong enough to visit.

Sends CD a letter from Mr Claydon responding to TR’s doubts and confirming the truth of a report that a farmer had "transmuted" oats into barley.

Sends a root of a wild oat-grass from California and the root of a variety of barley that came from it. Several varieties of barley, all differing from English varieties, came up in the same bed of oat-grass. "The transmutation of a genus seems almost incredible" but TR has seen so many changes he has ceased to doubt strongly.

Reports on a curious cross in peach varieties, in which the male made a firm large peach into a fruit more almond-like than itself.

Thanks CD for sending him Variation and for honouring his name by its frequent mention in the work.

Sends two vines for CD’s experiments, with instructions for grafting.

Mentions a hybrid plum–peach.

Thanks for vines and for all the information given him. Fears experiment will be more difficult than he had expected.
