<i>Ranunculus Yuexiensis</i> (Ranunculaceae): A New Species From Dabie Mountains, China, Based on Plastome and Morphological Data

A new species of Ranunculaceae, <i>Ranunculus yuexiensis</i>, is described and illustrated from the Dabie mountains, China. <i>R</i>. <i>yuexiensis</i> is similar to <i>R</i>. <i>ternatus</i> in having root tubers. However, it can be readily distinguished from <i>R</i>. <i>ternatus</i> by its simple and fewer basal leaves, larger flower size, long petioles on the lower stem leaves, and puberulent (vs. glabrous) carpels and achenes. The complete plastomes of this new species are 155,537-156,009 bp in length and exhibit a typical quadripartite structure. Phylogenetic analysis, based on plastome data, shows that <i>R</i>. <i>yuexiensis</i> is closely related to <i>R</i>. <i>ternatus</i>, which is consistent with our morphological analysis.
