Primulina was previously monotypic, but was now expanded to around 130 species mainly by the inclusion of taxa previously treated within Chirita sect. Gibbosaccus C.B. Clarke (1883), Chiritopsis WT.Wang (1981a), Wentsaiboea reni-folia D.Fang & D.H.Qin (2004) and W. luochengensis Yan Liu & WB.Xu (Liu et al. 2010, Wang et al. 2011, Weber et al. 2011, Xu et al. 2012). Recently, it has been further expanded to over 200 species (Li et al. 2019, Moller 2019, Wen et al. 2019, Xu et al. 2019). As now circumscribed, the genus is widely distributed, occurring from south-western, southern and eastern China southward to northern and central Vietnam (Wang et al. 1990, 1998, Moller et al. 2016, Vu 2017, Xu et al. 2017). In Vietnam, a total of 23 species have so far been recorded (Drake 1890, Merrill 1918, Pellegrin 1926, 1930, Burtt 1960, 2002, Wood 1972, Wang 1981b, 1983, Pham 1993, 2000, Nguyen and Kiew 2000, Vu 2005, 2017, Wang et al. 2011, Weber et al. 2011, Do et al. 2013, Zhao et al. 2013, Xu et al. 2017, Luu et al. 2018, Yang et al. 2018).
