448 Conifere—Cupressus. 
closely imbricated, obtuse, or acute usually furnished with an 
obscure tubercle towards the apex. Fruit small; scales with 
a small straight central prickle. This is one of the most invari- 
able evergreens in trifling details of habit and in hue of 
foliage, and a few striking varieties have been preserved. One 
raised by Mr. Anthony Waterer, of Knaphill, and named evécta 
viridis, is very distinct in its erect habit and deep green 
foliage. The variegated varieties wirea and argéntea are not 
so desirable as many other variegated shrubs. The names 
compacta, laxu, gracilis, stricta, nivea, minima, and in- 
termedia designate some of the varieties distinguished by 
nurserymen, and sufficiently explain their individual pecu- 
liarities. This magnificent and extremely hardy evergreen is a 
native of Upper California. 
C. fragrans, syn. C. aromidtica and C. Califérnica, is a closely 
allied species from the same region. ‘ It is a lofty slender tree 
with feathery branches and angular narrow acute light glaucous 
green leaves. 
2. C. macrocarpa.—aA tree of medium size with numerous 
stout spreading branches forming a flat top, and very dark 
green closely imbricated foliage. Fruit large. This is un- 
‘doubtedly one of the most splendid ornamental trees we have, 
but, although perfectly hardy in exposed places, it will not 
succeed well in a low humid situation. This is probably owing 
in a great measure to its extremely rapid and late growth, and 
consequent imperfectly ripened wood. C. Lambertiana scarcely 
differs even to the extent of a variety except in having pen- 
dulous branches when young. Upper California. 
3 0. Nuthaénsis, syn. Thuidpsis boredtis.—This fine species 
is better known in gardens under the latter appellation. It is 
a fast-growing tree from 80 to 100 feet high with numerous 
branches and drooping branchlets densely clothed with small 
closely imbricated very acute leaves destitute of tubercles, of a 
rich dark green, slightly glaucous on the lower surface or shady 
side of the branches. A very hardy and desirable evergreen, 
from North-western America. 
4. C. thyoides, syn. Chamecyparis sphceroidea. White 
Cedar.—A tree from 30 to 60 feet or more high. Branchlets 
slender, not plaited. Leaves very minute, closely imbricated, 
furnished with a small tubercle about the centre, light green, 
soon falling from the older branchlets. There are several 
varieties, and the one called varieydtu is very handsome, with
