canaliculate. Such leaves as do remain on the older and 
rounded branches are often twice the size of these, broadly 
ovate, acuminate, appressed to the bark, withered (especially 
the lower ones), and, owing to the spreading ofthe bark, with 
the increased size of the branch, set apart from each other, 
not imbricating. Only one of my specimens possesses any 
fruit, the one from the Straits of Magelhaen, and that a soli- 
tary and immature terminal oval capsule or strobilus. Two or 
three of the leaves immediately below it are elongated, and 
the fruit itself would appear to be formed of four terminal 
leaves thus elongated and linear, of which the bases are sin- 
gularly enlarged and dilated (upwards as well as laterally), 
forming the four coriaceous or almost woody valves of the 
fruit, two inner ones large and oval, the two other and outer 
ones smaller and oblong; the apex of the leaf thus converted 
remains in the form of an incurved spine, inserted below the 
apex of the valves. The fruit being a solitary one and im- 
mature, I have not ventured to destroy it for the sake of in- 
specting the seeds. 
The species, indeed, is a very distinct one in its characters, 
and undoubtedly ofthe genus Thuja. Yet there is described 
by Mr. Don, from the Lambertian Herbarium, gathered 
“by Mr. Middleton at Cape Horn," a Juniper, J. uvifera 
Lamb. Pin. ; * foliis ovatis obtusis appressis quadrifariam im- 
bricatis, ramulis congestis," etc., and, were it not that the 
fruit is described as that of a true Juniper, I should consider 
the two plants to be the same.
