Polymorphic, sympatric flavonoid variants of Claytonia perfoliata Donn from the Columbia River Gorge

Creator:

Miller, John M.

Abstract:

Claytonia perfoliata is a west-American polyploid complex of common annuals (x=6). The species is polymorphic; exomorphic characters are often variable within local populations. In a transect of the Columbia River Gorge diploids, tetraploids, hexaploids, octoploids, and decaploids were collected, which varied in shape of basal and cauline leaves, degree of...

AN ABSTRACT OF THE THESIS OF JOHN MICHAEL MILLER for the
Phenotypic variation in diploid and tetraploid populations of Claytonia perfoliata (s.l.) (Portulacaceae)

Creator:

Miller, John M.

Abstract:

Meiotic chromosome counts from 200 populations of Claytonia (Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based on three morphologically different, chemically distinct, and geographically defined diploids. The basic chromosome number is x=6. Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid mature basal leaves ranges southeastward from...
