First detected, but never described, by Forster, from whose collections we have a very small specimen, intermixed 

 with 0.ralis Magellanica. In the southern parts of Tierra del Fuego it is a very common plant, covering large tracts 

 of ground with a carpet of deep but shining green, upon which the stellate flowers have a very pretty appearance. 

 The similarity between the leaf of this and of the Dionaa muscipula, " American Fly-trap," is very striking.

Hab. Strait of Magalbaens and Fuegia ; first noticed by John Winter wbo accompanied Drake's voy- 

 age in 1577, and since by all voyagers and collectors. 



A very abundant tree throughout the western and southern parts of Fuegia, even in Herrnite Island ascend- 

 ing to 1000 feet. The natives use the stems of the young trees, rudely fashioning them into handles sometimes 

 ten feet long, for then harpoons ; but the wood is too soft and supple. The bark has proved a most useful sto- 

 machic and antiscorbutic to various voyagers, and especially to a portion of the crew of the ' Beagle ' during Capt. 

 King's arduous surveying voyage (vide King's Voyage, vol. i. p. 234.). 



After a careful examination of a'very extensive suite of examples, I have come to the conclusion that there is 

 but one South American species of this genus. There is a dissimilarity in the form of the foliage, even between the 

 North and South Fuegian states, the former having longer and more membranous leaves, differing in no respect 

 from specimens gathered near Valparaiso by GDUes, Cuming, and Bertero, which generally pass under the name of 

 D. CMlensis, DC. From Juan Fernandez again, the plants collected by the two last-mentioned travellers belong to 

 the same species : though the leaves are generally more linear, they are not so much so as in some of the continental 

 states. In Brazil, the variety, called D. Granatensis, L. fil., is found over the whole of that vast empire, and equally 

 occurs in New Grenada and the province of Santa Fe in Colombia. Mr. Gardner's number 5675 precisely accords
