The little-known Aloe labiaflava (Asphodelaceae subfam. Alooideae), which has for long been regarded as a hybrid between A. davyana and A. longibracteata, is reinstated as an accepted species endemic to a small area in the western Mpumalanga province of South Africa. It differs from both A. davyana and A. longibracteata in several reproductive morphological characters not present in these two species, especially by almost invariably producing only a single inflorescence per flowering season and by having a perianth that is distinctly flared at the mouth, with especially the external, apical ⅓ of the perianth conspicuously yellow.
