The number of "aquatic" flowers is reduced if one considers only those that expand under water.

Lecturing at Norwich.

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.

Having trouble understanding laws of phyllotaxy in order to grasp Hugh Falconer’s objections.

L. C. Treviranus on Primula [see 3980] misses the "prettiness" of the adaptations.

John Scott says P. scotica is never dimorphic.

Observation on morphology of Primula ovarium sent for DO’s use.

Nectar secretion in Edwardsia. Could the stamen protect stigma?

Sends monstrous Primula with three pistils.

Had never heard of Robert Caspary, but what DO thinks is the placenta could be a whorl of pistils without stigmas.

Asks DO to give enclosed [letter?] from John Scott to Hooker.

JS’s work on orchid self-sterility; Acropera has 371250 seeds in one capsule.

Wishes something could be done for Scott.

Working on monstrous Primula. Is ovule anatropous as Asa Gray says, or amphitropous? Does he know natural path of pollen tubes in Primula. Can the tube enter the ovule by the chalaza?

The ovule of Primula is amphitropous or what J. Georg Agardh calls apotropo-amphitropous [see Theoria systematis plantarum (1858), tab. 24, fig. 5–6].

Thanks for information on Primula ovules. From what DO says the pollen-tubes ought to find their way to the micropyle.

Encourages DO to publish his paper and put his name to it. [Paper apparently not published.] Concurs with his views on primordial nature of hermaphroditism.

Sends F. Hildebrand’s paper for publication by the Linnean Society or in Natural History Review.

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

Recommends Wyman’s short notice ["Report on Dr Jeffries Wyman’s experiment on the cause of contractility in vegetable tissues"] in the Proceedings of the American Academy of Arts and Sciences 3 (1852–7): 167.

Sends some specimens for CD.

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

Thanks for "multitudinous" references.

Thanks Hooker for orchids.

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.

Fertile flowers of violets, except Viola tricolor, require insect visits.

Gives a reference to a paper.

Botanists are obliged to regard tendrils as either leaf- or stem-formations. Vitis, Passiflora, and Clematis are discussed. [See 4398.]

Sends Hermann Crüger’s paper ["A few notes on the fecundation of orchids and their morphology", J. Proc. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35] for publication.

"Boasts" of confirmation that sexes are separate in Catasetum.
