This remarkable plant, first described by Hariot in 1887, appears to be 
frequent in brackish localities in the Cape Horn region. Mrs. Vallentin 
states that it was found * growing in abundance at high-water mark up Roy 
Cove Creek, where the water is brackish," and Hariot comments on its 
widespread distribution in Fuegia.

E. Falklands, Darwin. W. Falklands; St. George's Sound, Roy Cove, 
Vallentin. 
Disrris. General in N. and S. temperate seas, also in the Arctic Sea and 
tropical Ө. America. 
Not a single species of Corallina is listed in ‘ Flora Antarctica,’ though it 
is now known that several species flourish in the Magellan region, and there 
is a specimen collected by Darwin in the Hooker herbarium. Mrs. Val- 
lentin’s gatherings consisted of the short high-water form known as var. 
mediterranea, and she notes that the plant is scarce.

For the addition of this species to the Magellan region list I am indebted 
to Prof. К. Yendo, who, being well acquainted with the plant in the North 
Pacific, readily recognized the Falkland Island specimens. Ç. pilulifera is 
much confused in herbaria, and is found under C. squamata, C. officinalis, 
and C. armata. For its distinctive features, see Yendo, l. c.
