Bayesian tree of the nrDNA ITS data, showing relationships of genera in subtribes Caraganinae, Chesneyinae and their close relatives. The labeled sections of Gueldenstaedtia and Tibetia followed Tsui (1979) and Zhu (2005a), respectively. Bayesian posterior probabilities (PP ≥ 0.95) and maximum likelihood bootstrap (LBS ≥ 70%) are given above and below branches, respectively. The asterisk indicates the name of Chesneya macrosperma has not been published, its voucher was storied in LE (details see Zhang et al. 2015b).
