Abstract

Over 1,000 herbarium specimens including 24 type specimens were examined in an attempt to achieve a clearer understanding of the Phlox longifolia complex. Four variables were measured for each specimen and the data were statistically analyzed by disciminant analysis. Using a previously published system of classification for the complex approximately 73% of the measured variation among the specimens was accounted for by that system. The clustering patterns produced in this first analysis indicated that a more conservative approach would be advisable. The formulataion and subsequent application of a modified system produced a grouping of specimens that accounted for 95% of the variation for the four morphological characters considered. From four species and seven subspecies previously recognized, one species wih five varieties is proposed. The typification fo Phlox longifolia Nuttall and other related taxa is resolved.
