Aloe perfoliata is a very poorly known species. As it is the type species of the genus Aloe, taxonomic rules dictate that the name should be upheld. However, it is not known which Aloe species this name applies to, as the type specimen is too poor to match to any known Aloe species. Because Aloe perfoliata is not known in the wild, an assessment of its risk of extinction cannot be done.
South African endemic
This species is only known from the type specimen, which has no locality description. The specimen is assumed to have originated from South Africa, but the distribution is not known.
Habitat and Ecology
Major system
The habitat of this species is unknown.

Aloe perfoliata is only known from the type specimen, which has no collector, collection date or locality information associated with it. As the species was described in 1753 (Linnaeus 1753), the specimen therefore dates to some time prior to 1753. As the specimen has not been matched to any wild populations of Aloe, the status of the population is not known.

Population trend
Aloe perfoliata is the type species of the genus Aloe, described by Linnaeus in Species Plantarum in 1753. The type specimen in the Linnaean Herbarium is however very poor, consisting of a single inflorescence without any leaves (Klopper et al. 2016). It has not been possible to match this specimen with certainty to any known Aloe species (Klopper et al. 2016), although some authors, e.g. Reynolds (1969) and Glen and Hardy (2000) applied the name to a species now known as Aloe mitriformis (Van Wyk and Smith 2014).
