This is an indicative distribution map of the present distribution of the species based on best available knowledge. See map caveat for more information.
The Masked Eyebright is a short-lived perennial herb, usually less than 30 cm high, with creamy white flowers that can possess deep purple striations (Threatened Species Unit 1997c).
The two known populations of this species are approximately 10 km apart on the Tasman Peninsula, SE Tas. (Threatened Species Unit 1997c).
One population occurs on low cliffs between Canoe Bay and Bivouac Bay. The other population on Cape Pillar extending along cliffs from Perdition Ponds and near the Oasis, to Arthurs Peak near Budget Head (Threatened Species Unit 1997c).
Access challenges make population estimates difficult. A rough 1995 estimate for the population between Canoe Bay and Bivouac Bay is 100-200 individuals. In the same year, approximately eight individuals were located at Arthurs Peak and approximately 20 at Cape Pillar, at the extreme ends of the other population. The actual numbers in these latter two areas are likely to be significantly greater (Potts 1997 in Threatened Species Unit 1997c).
The three known localities representing two populations occur in the Abel Tasman Forest Reserve and the Cape Pillar State Reserve (Threatened Species Unit 1997c).
Euphrasia fabula is contained within the close-knit E. phragmostoma, E. amphisysepala, E. fabula group (Potts & Barker in prep). The species' true identity is masked until flowering. It is thought that variation in this group has arisen through hybridisation (Threatened Species Unit 1997c).
The species is generally restricted to dolerite cliff faces, tending to be found on ledges, rock crevices and patches of bare ground, extending from the base to the tops of coastal cliffs. The species has a preference for relatively moist and shady areas, where the vegetation is not too dense. It may extend away from the cliff edges after fire due to the increased openness, but will retreat to cliff faces as the vegetation thickens (Threatened Species Unit 1997c).
Populations of Euphrasia species are transient. The persistence of populations is reliant upon the successful recruitment of seedlings. Patches of open ground are required for germination, and adequate moisture levels are required for seedling survival. Seed production is copious and the soil seed bank probably survives for decades. Profuse germination occurs after fire (Potts 1999).
Euphrasia species are non-host specific semi-parasites. The growth rate and reproductive output is reduced in the absence of hosts (Potts 1999).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
