Conservation Status

Last record: 1952 (Hilton-Taylor, 1997:205)

Rediscovered in 1997 (Raimondo, 2007)


Dümmer (1912:29) considered the species as possibly extinct when scientifically describing it, as it putatively occurred in a well botanised area without recent record. Hilton-Taylor (1997:205) states that it is only known from four old collections, the last of which dates from 1952. Still listed as Extinct by (Humphreys et al., 2019).
