Maw had sent CD a fragment of a fern-leaved beech (Fagus sylvatica ‘Asplenifolia’) bearing a branch of the normal form of foliage (see letter from George Maw, 18 June 1866 and n. 2). In Variation 1: 382, CD referred to other cases in which the buds of the fern-leaved beech had reverted to the normal form; or had reverted only partially, so that branches bore both normal and fern-like leaves, as well as variously shaped leaves. CD cited information from Braun 1853, p. 315, and Gardeners’ Chronicle 1841, p. 329.
