Thanks CD for his paper on Lythrum [Collected papers 2: 106–31].

Astonished by CD’s powers of observation and perseverance.

His elms raised from three varieties of weeping elms are doing well.

Thanks CD for "Climbing plants" [see 4861].

Encloses sketch of a climbing French bean.

Tells of a row of non-climbing haricot beans that in good season put out slender climbing shoots.

He has the peach almond in fruit this season.

Will be sure to send the Cytisus and Laburnum blooms when they flower.

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.

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.

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.
