Conservation Status
Extinct (POWO, 2023; contra Humphreys et al., 2019)
Last record: 17 July 1852 (Vladimirov et al., 2021:401)
Claimed to have been rediscovered based upon a herbarium specimen collected on 2 June 1996 (Humphreys et al., 2019), but the identification is wrong and the species is still known only from the type collection (Vladimirov et al., 2021:401,403).
