† unliningn.

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: un- prefix², lining n.¹

Etymology: < un- prefix² + lining n.¹, after French dédoublement (a1755 in general sense ‘action of dividing something in two’, 1826 or earlier in the specific botanical use, attributed to M.-F. Dunal by A. Moquin-Tandon Essai sur les dédoublemens (1826)).

Botany. Obsolete.

In the development of a flower: division of a floral organ, esp. a stamen or petal, into two or more identical structures resulting in an increase in the number of such organs; an instance of this. Cf. unline v.² 2.Cf. chorisis n., deduplication n.Unlining was originally thought to involve the separation of two layers.

1835 J. Lindley Introd. Bot. (ed. 2) vi. i. 541 There is no difficulty in rejecting the hypothesis of dédoublement (unlining) of Dunal, which assumes that in a flower every organ consists of two parts, one standing in front of the other, and forming what he calls a chorisie.

1848 J. Lindley Introd. Bot. (ed. 4) I. 332 Here we have a succession of true unlinings; but in Crucifers..the large stamens offer an example of simple unlining in the full meaning of the word, since they present a separation into two parts only.

1853 A. H. Lincoln Familiar Lect. Bot. (new ed.) xiii. 69 If they [sc. stamens] are more numerous [than the pieces of the calyx or corolla], this is owing to the development of one or more additional whorls by dedoublement, or unlining.

1862 M. C. Cooke Man. Bot. Terms 87 Unlining, a separation of parts originally united.

1901 L. L. Lamborn Amer. Carnation Culture (ed. 4) xxviii. 161 There is a pseudomorphous unlining of the inner series or whorls of floral leaves.

1914 Biometrika 10 219 The formation of these scales is supposed by many to be due to the chorisis or unlining of an inner portion of the petal from the outer.
