Answers CD’s query on Primula longiflora and P. scotica.

Would like abstract of CD’s paper ["Two forms of Linum", Collected papers 2: 93–105] for Natural History Review.

Discusses the female parts of the Primula flower; the true character of the free placenta is not completely understood.

Sends some specimens for CD.

Is busy with W. African Amomum, whose floral structure he discusses.

Hildebrand’s paper is unsuitable for the Natural History Review.

Gives a reference to a paper.

Discusses the contraction of hygroscopic bundles in seed-pods,

and a paper by Hugo von Mohl ["Über dimorphe Blüthen", Bot. Ztg. (1863): 309–15, 321–8] in which he discusses Oxalis and determines that Fumaria is a necessarily self-fertilising plant.
