Penkimia may be related to Ascocentrum and Holcoglossum. Chenorchis singchii was described as a new genus and species by Liu et al. (Acta Ecol. Sin. 28: 2433-2444. Jun 2008). Its holotype (Yunnan: Tengchong, Wuhe, 1650 m, 16 Feb 2008, Z. J. Liu 3862, NOCC) is from the same area as the first Chinese gathering of P. nagalandensis (Yunnan: Tengchong, Wuhe, 2000 m, 15 Mar 2007, X. H. Jin 8923, PE) reported five months after the publication of Chenorchis by Jin and Fan (Acta Bot. Yunnan. 30: 531-532. Oct 2008). Penkimia was described as a new genus in 2006 and therefore has priority.
