Assessor(s): Jakubowsky, G. (University of Vienna, Institute of Botany)
Reviewer(s): Cronk, Q. & Cairns-Wicks, R. (South Atlantic Island Plants Red List Authority)
Justification:
Collected only once on Tristan da Cunha (Christophersen 1944) and later twice on Gough Island by N. M. Wace, on Gough also found recently by Christine Hänel (pers. comm.). According to Wace (herbarium label) it is frequent but rarely flowering on Gough. Since it is also flowering late (February) and could be confused with Carex vegetatively it is probably easily overlooked and more common than the small number of collections indicate. More research on distribution and population size is needed.
