My dear Sir
You very greatly over-rate the labour of my Bibliography & yet more
greatly extravagant is your notion as to my knowing many things.— Alas! I am dreadfully ignorant & my memory
sadly imperfect.— Your suggestion about the sexes of water
plants is interesting. In this relation it would be important
to distinguish species the flowers of wh. expand under the
surface,—& this w
I am not aware that any sexual difference has been noticed in its
flowers. Acct. w
My prospect of spare time keeps far off. Tomorrow even
Very sincerely yours | Dan

An obs. of mine in a Review of British Floras suggested his looking for them.—

The flowers of the first group open on the surface of the water, while those of the second group expand while submerged; Oliver considered only the latter to be truly aquatic. There is a note on aquatic plants in DAR 111: A69. See also letter to Daniel Oliver, 20 [January 1863]. - +

Oliver refers to the motile male gametes (antherozoids) of some algae, and to some seaweeds containing male and female sex organs in the same conceptacle, a cavity in the thallus. - +

In his anniversary address to the Linnean Society, George Bentham discussed the subject of biological classification; he cautioned against remodelling the taxonomic system by creating new species and new names (Bentham 1862). Bentham was referring to the recent contribution on Rubus by Philipp Jakob M¨uller (M¨uller 1859), a 225-page account of 239 species of the genus, and to M¨uller 1861, a 40-page account describing 31 new bramble species. In the conclusion to Origin, CD predicted a `considerable revolution in natural history' once his views were acknowledged, resulting in the cessation of the `endless disputes' about `whether or not some fifty species of British brambles are true species' (Origin, p. 484). - +

In the January 1863 number of the Natural History Review, Oliver reviewed new editions of a number of standard British floras, including the fifth edition of Charles Cardale Babington's Manual of British botany (Babington 1862) and the eighth edition of The British flora by William Jackson Hooker and George Arnott Walker Arnott (W. J. Hooker and Arnott 1860). Here ([Oliver] 1863b, p. 38), Oliver criticised the `wholesale manufacture of species', which caused such `mischief' when it came to philosophical generalisation or comparison.
