APIUM AUSTRALE, Thou. Esq. Fl. Trist. p. 43; Hook. f. Handb. 
Fl. N. Zeal. p. 905 Hemsl. Chall. Bot. i. 11. p. 149. 
Common on the low-lying ground down to high-water mark 
and growing very rankly in places. It appears to be a very 
variable plant, and the Gough Island variety has the leaves 
broadly ovate, and not linear like the specimens from Tristan da 
Cunha of Carmichael and Moseley. 
Distribution. Tristan da Cunha and Inaccessible Island, and 
very generally in extra-tropical regions of the Southern 
Hemisphere.

Erythrodanum alsineforme, Thou. Esq. FL Trist. p. 42, t. 10 
(Nertera). 
Common in the drier and more barren places. 
Distribution. Tristan da Cunha and Inaccessible Island, and 
southern temperate regions except South Africa. 
NERTERA DEPRESSA, Gaertn., var. OBTUSA, Rud. Br. 
A variety distinct from the normal Nertera depressa in having 
all its leaves obovate with no suggestion of acuteness. 
Among the specimens of Nertera depressa gathered on Gough 
Island only one plant of this variety was found. In the Kew 
Herbarium there is one specimen from Inaccessible l:land 
(Moseley, Inaccessible Island, 16.8.73) of this variety. Theother 
specimens of this plant. from Tristan da Cunha belong to the 
typical Nertera depressa, and the variety does not appear to occur 
elsewhere. 
Distribution. Inaccessible Island.
