Summary:
Questions on variation in nature: taxa varying in one region but not another. Variation between vs within species. Rarity of variation in important organs within a species. G. R. Waterhouse’s views on variation in highly developed organs, which CD relates to variation in rudimentary organs.
Asks for cases of obligate self-fertilising plants.
[CD annotation proposes using the Steudel Nomenclator botanicus (1821–4) to determine if variable species occur in genera with many species.]
