1. S. gigantea, syn. Wellingtinia gigaiutea, Washingtinia 
gigantea, etc. Mammoth Tree.—A colossal tree with dense 
slender branches thickly clothed with small leaves at first 
needle-shaped and spreading, at length scale-like and closely 
imbricated and appressed, of a bright light green. Cone about 
2 inches long, oblong; scales woody, persistent, wedge-shaped. 
This marvellous tree exceeds all others in its gigantic propor- 
tions, not excepting the enormous Gum-trees of Australia and 
Tasmania. One that was felled and stripped of its bark 
measured 327 feet in height, and 90 feet in circumference at 
the base ; and another was discovered broken off at a height of 
300 feet, where it was 18 feet in diameter, hence it is con- 
tended it must have been about 450 feet high altogether. It 
measured 112 feet in girth at the base. It is a native of 
various parts of the Sierra Nevada in Upper California, where 
it was first discovered, it is reported, by an American hunting 
party in 1850. But the English collector, Lobb, appears to 
have been the first to introduce it into our gardens during the 
year 1853. It is also stated that Douglas saw it as early as 
1831. However that may be, we may now count it by hundreds 
of thousands in this country, and some specimens have already 
attained a height of nearly 40 feet. Although this noble tree 
is generally known in this country by the name of Wellingtinia 
gigantea, we oust remind our readers that from a scientific 
point of view this name is untenable, and must give way to 
that adopted by us, and now admitted by most botanical writers. 
Doubtless the tree will retain Wellingtonia as its popular name, 
in the same way as we call Pelargoniwms Geraninms in common 
parlance. 
2. S. sempervirens, syn. Taxddiwm sempervirens. Red- 
wood.—This also is a very lofty tree, towering to the amazing 
height of 200 to 300 feet. It was first discovered by Menzies 
in 1796, and until the species just described became known, it 
was justly considered as the ‘Giant of the Forest.’ Branches 
numerous, slender. Leaves distichous, linear, flat, acute, soft * 
flexible, from 6 to 9 lines long, dark glossy green above, and 
silvery beneath. Cones about an inch long, nearly spherical, 
with thick woody scales terminating in a hard point. This 
species is scarcely so hardy as the Wellingtonia, but it will
