Movement and sensitivity of flower parts; relationship to cross-fertilisation.

Federico Delpino on mechanical movements of flower parts of Maranta. CD’s observations on Maranta, and his eagerness to compare cases of movement and irritability in plants.

Thanks for plants and seeds; requests for more to test Sachs’s notion on "bloom".

GB’s note has given him more pleasure than his election to the French Academy.

Heliotropic responses in aerial roots and tendrils.

Sends seeds received from Fritz Müller.

Has been reading WTT-D’s lecture ["Plant-distribution as a field for geographical research", Proc. R. Geogr. Soc. 22: 412–45].

Heliotropism in roots.

Francis Darwin’s work on "bloom" and its relation to stomata.

Movements of flower-stalks of Oxalis.

Wants some plants for sleep-movement observations. Has almost finished experimental work and must start sorting his notes.

Wants Impatiens seeds, in order to observe movements of cotyledons.

CD hopes his book [Movement in plants] will be worth the effort WTT-D has put into getting plants for him; fears he has achieved little.

Movements in Oxalis.

Heliotropic movements. Is giving up experiments until the spring.

Wants to borrow Duchartre’s Éléments de botanique [1867].

Thanks for book [Duchartre, Éléments de botanique].

Thanks for second edition of Duchartre.

Thanks for seeds and for kindness to Frank Darwin.

Wants a Cassia identified

and several plants and seeds for experimental purposes.

Thanks for the plants for heliotropic experiments.

Thanks for WTT-D’s trouble.

Has been writing life of Erasmus Darwin.

Wants plants with heliotropic aerial roots. Has proved root apex governs nature of flexure in upper part of root.
