Citrus × pubinervia, a new natural hybrid species from central China

Abstract

Citrus × pubinervia D. G. Zhang & Z. H. Xiang, Y. Wu, a new hybrid species is described and illustrated from central China. This new species is closely related to C. × polytrifolia in evergreen treelets and petiole with narrow wings but mainly differs from the latter by glabrous petals and glabrous fruits. The molecular phylogenetic analysis which based on four cpDNA (matK, rbcL-atpB, trnL-trnF, psbA-trnH) verifies the results of morphological analysis.
