Telosynapsis or Structural Hybridity in Œnothera?

Abstract

IN a recent article¹ I have put forward a hypothesis which I consider provides an explanation in terms of segmental interchange and parasynapsis of (i) the occurrence of ring-formation in Œnothera, (ii) its inheritance on selfing and crossing, and (iii) the occurrence of mutant forms differing in properties of ring-formation from their parents. These seem to be the essential requirements of a working hypothesis expressing the relationship of Œnothera with other plants and animals. Further, the premises on which the hypothesis is based have been defined very fully in later articles.^{2, 3, 4, 5}
