Chorispora sabulosa and C. elegans were simultaneously published by Cambessèdes. Hooker and Thomson (J. Proc. Linn. Soc., Bot. 5: 181. 1861), who were the first to record the species from Xizang, listed the latter name as a synonym of C. sabulosa, which name therefore has priority under Art. 11.5 of the St. Louis Code. The species was not listed in FRPS or in Fl Xizang. (vol. 2. 1985), but the record from Xizang is here confirmed by the study of material cited by Hooker and Thomson (loc. cit.) and also by Jäschke s.n. (WU).
