As far as I know, there are hardly any references to
tricotylous races in botanical literature, and the possibil-
ity of the existence of tricotylous intermediate races
seems never to have been discussed. In this part,
however, I shall describe some instances of such races
in order to demonstrate their existence and study their
characters. In the period from 18921897 I succeeded in
producing such races from half a dozen very different
species. De Vries (19091910).
Introduction
The maintenance of apparently fixed characteristics of
organisms is little-studied in evolutionary biology
(Stearns, 1994; Karoly & Conner, 2000). The obvious
