Dr. Lindley, remarks on the perfect series which may be formed between the
almond and the peach. Another high authority, Mr. Rivers, who has had such
wide experience, strongly suspects ('Gardener's Chronicle,' 1863, p. 27)
that peaches, if left to a state of nature, would in the course of time
retrograde into thick-fleshed almonds.

[640] Whether this is the same variety as one lately mentioned ('Gard.
Chron.' 1865, p. 1154) by M. Carriere under the name of _Persica
intermedia_, I know not: this var. is said to be intermediate in nearly all
its characters between the almond and peach; it produces during successive
years very different kinds of fruit.
