Campylotropis anningensis (Fabaceae, Papilionoideae), a new species from Yunnan, China

A new species, Campylotropis anningensis L. S. Jiang, E. D. Liu & Bo Xu bis, is described and illustrated. It is similar to C. argentea, C. pinetorum, and C. sulcata, but can be distinguished by its ascending white-pubescent branchlets; ovate, ovate-lanceolate to linear-lanceolate stipules; elliptic, narrowly elliptic to narrowly elliptic-lanceolate leaflets with appressed white-sericeous hairs on the abaxial surface; axillary and terminal racemes with white-pubescent and glandular hairs; lanceolate bracts; longer standard and wings; vexillary stamen connate to the staminal tube only at the base; and obliquely ovate legumes that are densely ascending-pilose.

Phylogenomic analysis based on 1,233 single-copy nuclear genes (SCGs) confirms that this new species is distinct from morphologically similar taxa. Conservation status of this species is assessed as Least Concern (LC) according to IUCN Red List criteria.
