Discusses the ranges and distribution of varieties relative to the type species.
Believes that botanists tend to mark more varieties in large than in small genera, but notes that where many varieties of a species exist these varieties may well be passed over, whereas similar varieties of another species which are fewer in number may well be recorded.
Discusses the ranges of species in large and small genera; difficulties involved in limiting the discussion to Britain.
Extracts from MS of vol. 4 of HCW’s Cybele Britannica [1847–59] showing the diversity of views on species among botanists.
