[ad. G. eucyclisch (A. Braun 1858, in Jahrb. f. wissenschaftliche Botanik I. 367), f. eu- + cyclic a.]
Cyclic with alternate isomerous whorls (see quots.).
1875Bennett & Dyer tr. Sachs's Text-Bk. Bot. ii. v. 524 Braun calls those flowers eucyclic in which the members of all the whorls are equal in number and alternate. It also happens however that members of the same kind arise subsequently between those of a whorl already formed; as..in many eucyclic flowers with ten stamens. 1878Henfrey & Masters Elem. Bot. (ed. 3) i. ii. 91 A flower thus presenting all the whorls is called complete or eucyclic. 1910Encycl. Brit. X. 560/1 When a flower consists of parts arranged in whorls it is said to be cyclic, and if all the whorls have an equal number of parts and are alternate it is eucyclic. |
