possible that the name C. Boursiert should replace that of Zaw- 
soniana,—a contingency that would be greatly to be regretted, 
as the name of one of the most active and intelligent intro- 
ducers of rare Conifers is now deservedly and indissolubly 
connected with this beautiful plant. 
Gordon compares C. Lawsoniana with C. Nootkaensis, and 
justly, the plants bearing a considerable resemblance in a 
living state, and being with difficulty distinguished in the 
herbarium: C. Lawsoniana is, however, a much more fea- 
thery species, with more fan-like branches and slenderer 
branchlets; the leaves also are of a glossier green, and the 
cones quite different, being smaller, glaucous, with a trans- 
verse, flat, acute, horizontal or recurved plate across the boss, 
very different from the more conical horn of C. Nootkaensis. 
The genus Chamecyparis, to which both these species have 
been referred, is utterly futile, its only character, that of the 
scales bearing two instead of many ovules as in most Cy- 
presses, breaks down in the present species, whose ovules 
vary in number from two to four or even five or six. 
Descr. A large tree, said to attain a hundred feet in height, 
with a narrow pyramidal coma. Branches spreading, fan- 
like and feathery in aggregate. Branchlets tetragonous, 
slender. eaves ovate or triangular-ovate, acute, appressed, 
convex on the back and there furnished with a rather obscure 
gland. Cones globular, one-fourth to one-third of an inch in 
diameter, of about eight decussating scales. Scales rhom- 
boidal, with a flattened and transverse lamina at the back of 
the boss. Ovules two to four at the base of each scale. Seeds 
with two wings.—J. D. H.
