328 FLOKA ANTARCTICA. [Fuec/ia, the 



cerudhoides, Br., as having this structure, and it is a singular circumstance that these two plants, which, through 

 their bilocular anthers and hypogynous filaments, completely unite the Ericea of the northern hemisphere with their 

 southern representatives in Australia, the Epacridea:, are both natives of very humid climates and densely wooded 

 regions, and not of such localities as the majority of cither Order (but especially the Epacridea) affect. 



The subscandent habit of L. Amerieanus is very peculiar ; it grows on the trunks of trees, and often creeps up 

 them for some feet. This is also the case with some other distichous-leaved Antarctic plants, as Callixene, and 

 Lusuriaga, and with the Prionotes and Decaspora of Tasmania.

I can hardly consider Mr. Darwin's specimens to be even a variety of the plant collected by Capt. King at 

 Cape Fahweather (not Port Jamaica, vid. Griseb.), on the coast of Patagonia. 



Except the rather broader and more obtuse segments of the less deeply divided calyx, there is nothing to 

 distinguish this from the Tasmanian and New Zealand G. montana, Forst.

This plant, the common English Bind-weed, is universally diffused throughout the temperate regions, both of 

 the northern and southern hemispheres. In the latter it inhabits New Holland, New Zealand, and the Island of 

 Java, according to M. Choisy, in DC. Prodr. 1. c.
