“…Several authors have chosen to recognize all taxa uniformly as varieties (Hitchcock andCronquist 1961, 1973;Russell 1965;Scoggan 1978) or subspecies of V. nuttallii (Peck 1961;Taylor and MacBryde 1978). Davidse (1976), in the most recent work on this group, undertook an extensive cytological investigation of the members of the Chamaemelanium section, including some Nuttallianae, in the intermountain region between the coastal Sierra Nevada mountains and the Rocky Mountains.…”

1987. The taxonomy of the Viola nuttallii complex. Can. J. Bot. 65: 2562 -2580.Morphological, cytological, and phytochemical data were incorporated into numerical and statistical analyses to produce a revision of Viola subsection Nuttallianae. A basic chromosome number of x = 6 was confirmed for this polyploid~complex, which includes five species: V. vallicola, 2n = 12; V. tomentosa, 2n = 12; V. nuttallii, 2n = 24; V. praemorsa, 2n = 36 and 48; and V. bakeri, 2n = 48. Departures from recent authors include the recognition of two varieties in V. vallicola, vallicola and major (Hook.) Fabijan, based on flavonoid chemist~y and distribution. Violapraemorsa is envisaged as embracing a wide range of morphological and chemical diversity, the extremes of which are recognized as the subspecies praemorsa, flavovirens (Pollard) Fabijan, and linguaefolia. In the absence of significant morphological or distributional differences between the V. liinguaefolia and V. praemorsa subspecies major (sensu Baker and Clausen) and oregona, these three previously recognized taxa are included in subspecies linguaefolia. Based on cytological, morphological, and flavonoid data presented here, possible phylogenetic relationships are discussed. FABIJAN, D. M., PACKER, J. G . , et DENFORD, K. E. 1987.

For for those instances where species were not clearly resolved in the initial analyses, a PCA on those species alone was done to see if the resolution could be improved by excluding those species that strongly polarize the data.…”

The relationships among the nine species of Glyceria occurring in British Columbia were evaluated using principal components analysis of morphological features. The analysis resolved five distinct species and two groups, each consisting of a pair of similar species. Independent analyses of these two groups indicated both consisted of different, albeit close, species. The interpretation that quantitatively similar species are distinct is corroborated by qualitative differences among those same species. A key to the nine species is included.
