Streblorrhiza speciosa Endl., 1833

Phillip Island glory pea



Taxonomy & Nomenclature

Synonym/s: Clianthus carneus Lindl.


Conservation Status

Extinct (Humphreys et al., 2019); "almost certainly extinct in the wild" (Silcock et al., 2019, 2020:7, 2021:7)

Last record: 1830 (wild) (Silcock et al., 2020:7, 2021:7); 1860?; later in cultivation in Britain? >1840?

IUCN RedList status: Extinct


This species has been identified as one of the 50 best candidates for de-extinction, ranking 3/50 (Albani Rocchetti et al., 2022). Given that it was cultivated in Europe, where it apparently survived longer than in its native habitat, there is the possibility "of some plants still in cultivation in Europe, but searches unsuccessful" (Silcock et al., 2020:7, 2021:7).
