1916 F. E. Clements Plant Succession 115 Alternation is the consequence of disturbed or incomplete zonation. Such areas produce alternes, which it now seems can always be related to more primary zones. This has already been shown in the case of the alternes of cañons, which are only the upward or downward extension of zones.

1926 A. G. Tansley & T. F. Chipp Aims & Methods Study Vegetation iv. 53 When there is no such regular spatial or temporal change, different communities alternate with one another, and the different areas occupied by these may be called alternes in contrast to zones.

1950 Ecol. Monogr. 20 260/1 The broad alterne was rapidly returning to big bluestem.

1996 G. Goodland Littoral 45 There are places on this hill where the conifers don't take, the corduroy treelines give out, exposing the yellow alterne of autumn scrub, briaries shifting in wind.
