Abstract
The circumscriptions of sections Auganthus Pax ex Balf. f. and Ranunculoides Chen et C. M. Hu in the genus Primula L. have been controversial, due to the different treatments of P. filchnerae Knuth. We conducted a phylogenetic analysis using sequences from the M region of nuclear ribosomal DNA. All five species of these two sections and some representatives of other related sections were sampled. The ITS trees show drat P. filchnerae could be convincingly placed in sect. Auganthus, together with P. sinensis Sabine ex Lindl, and P. rupestris Balf. f. et Farrer, whereas sect. Ranunculoides contains two species: P. cicutarifolia Pax and P. merrilliana Schltr. These two sections are distantly related and their association with other,sections needs further studies. This study also demonstrated that US sequences would be a Suitable marker for die reconstruction of Primula phylogeny.
