Mr. Lowe states in his ‘Flora of Madeira’ (quoted in ‘Gard. Chron.,’ 1862, p. 215) that the P. malus, with its nearly sessile fruit, ranges farther south than the long-stalked P. acerba, which is entirely absent in Madeira, the Canaries, and apparently in Portugal. This fact supports the belief that these two forms deserve to be called species. But the characters separating them are of slight importance, and of a kind known to vary in other cultivated fruit-trees.
