My Dear Sir/

Dr Hooker—who is down in the West Country—sends me yr. letter abt. Sundews &c.—1 I send this morning by carrier—2 sheets of Byblis-Roridula for yr. examination—which you can return kindly at yr. convenience.2

Then, with this I put in fragts. of several Utricularias which have special circular arrangements as well as simple leaves—probly. most of them growing amongst moss or in marshy places.3

Of the group to which U. montana belongs I only know some 3 species altogether—with the [stated] “Orchidioid” appendages:— hence name of the Section (Orchidioides).4

The boy is waiting for the letters so in haste

Ever yours | D Oliver

See letter to J. D. Hooker, 9 October 1874 and n. 1. Oliver sent dried Byblis gigantea (rainbow plant) and Roridula dentata (see Insectivorous plants, pp. 342 and 343).
See letter to J. D. Hooker, 9 October 1874 and n. 5. The section Orchidioides in the genus Utricularia (bladderworts) was originally published by Augustin Pyramus de Candolle in 1844 (A. P. Candolle and Candolle 1824–73, 8: 23–4), with two species given: U. montana (now U. alpina), and U. unifolia. Several species are now recognised within this section (see Taylor 1989).
