摘要
The hitherto poorly-known Micranthocereus aureispinus Ritter (Cactaceae) is reinstated as a species following its rediscovery in fertile condition within a protected area. It should not be regarded as a synonym of M. albicephalus (Buining & Brederoo) Ritter and may have a closer relationship with M. violaciflorus Buining. M. oliveirae P.J. Braun (2015) is a synonym of M. aureispinus.
