Has. Straits of Magellan. Forster. Falkland Islands. Mr. 
Wright. : 
The first aspect of this plant is rather that of Carax pulicaris 
or some allied species of that genus, than of Triglochin, from 
which genus I think it may fairly be separated, no less on ace 
count of its peculiar habit, which is harsh and rigid, than of its 
dicecious flowers, reflexed and tetramerous fruit. I possess 
only specimens with immature fruit.
