Rhododendron albiflorum Hook. (Ericaceae): one taxon or two?

Populations of Rhododendron albiflorum Hook. in Colorado are disjunct by ca. 1470 km from populations in the Pacific Northwest. Morphological data showed that plants from the two sets of populations differed in length and width of petals and length of stamens. Genetic identity figures based on analy...

Zusammenfassung:	Populations of Rhododendron albiflorum Hook. in Colorado are disjunct by ca. 1470 km from populations in the Pacific Northwest. Morphological data showed that plants from the two sets of populations differed in length and width of petals and length of stamens. Genetic identity figures based on analysis of isozyme electrophoresis found Colorado and Pacific Northwest populations to have an Ī value of .76. These morphological, geographical and isozymic data support recognition of the Colorado plants as Rhododendron albiflorum Hook. var. warrenii (A. Nelson) M. A. Lane, comb. & stat. nov.; the Pacific Northwest plants are Rhododendron albiflorum Hook. var. albiflorum.
