or five fided, with a toothed umbo in the centre, pointing ftraight outwards; feeds [fig. io, natural fize, 
and fig. ii, magnified], feveral to each fcale, coloured dark brown, proportionally large, 
flat, fomewhat ear-fhaped ; germinal fhoot bifoliate [fig. 12]. 
This fpecies bears a great refemblance to Siebold’s genus Retinifpora. The chief 
characters of that genus are, that each fcale bears only two feeds, and that the feeds 
themfelves are marked with refinous blotches under the fkin. This fpecies poffeffes the latter characters 
but not the former; but our examination of Siebolcl’s fpecies of Retinifpora does not bear out his char¬ 
acter in regard to the former. We fee more than two feeds to each fcale in R. obtufa and R. pififera. 
We imagine, therefore, that the genus Retinifpora will not ftand.

Defcription. —A fine tree, about 100 feet in height and two feet in diameter. The foliage delicate 
and graceful. The branches firft depend like thofe of a Spruce, and then rifing gently, hang clown at the 
end like an oftrich feather. The top fhoot droops like a Deodar. The colour is of a delicate glaucous 
green. It has fome refemblance to Cuprejpus. Nutkaenfes (Thujopfis borealis ), but is much more flender 
and delicate in habit. Its cones are like thofe of Retinifpora pififera, but of a fofter texture, and the foliage 
is different. The beauty of its colour, gracefulnefs of its habit, and hardinefs, have effablifhed this fpecies 
as one of the mofl favourite of the Cyprefs family. The tailpiece vignette is a portrait of the original 
feedling, now 8 feet high, growing in our Nurferies near Edinburgh. 
A fpecies very clofely allied to this was difcovered by Mr Beardfley and defcribed by Mr Killog, 
under the name of C. fragrans * (See “ TranfaCtions of the Academy of Science, San Francifco,” 
p. 103.) Its chief differences feem to be the fize of its fruit and the 
number of the fcales. In C. Lawfoniana the cone is about the fize of a 
pea, and has fix peltate fcales ; in C. fragrans , of a hazel nut, and has 
nine peltate fcales. We have reared both, and we find little or no differ¬ 
ence in the embryonal leaves. Fig. 12 fhews their appearance in the true 
C. Lawfoniana ; fig. 13 that in C. fragrans. 
It differs, moreover, according to Mr Killog, mofl ftrikingly from C. Lawfoniana , in the brighter green 
of its foliage and its far denfer branchlets: alfo in the leaves being narrower, much more angular, and 
fharper pointed. The cones are from one-third to twice the fize, brighter in colour, more rough in form, 
and more fparfe in diftribution, &c.; it is alfo a tree of larger proportions in all refpefits. Mr Killog s 
fpecific name was chofen to reprefent its quality par excellence. He knew of no fpecies fo agreeably 
fragrant, the wood abounding in an oil which exhales a peculiar fpicy aroma, in which the ginger flavour 
predominates. This notable odour has fometimes given it the common name of the Ginger Pine among 
lumber men. Some fpeak of it as White Cedar; in the market it is alfo known by the more indefinite 
name of Oregon Cedar. 
It is with great he.fitation that we have kept it diftinfit from C. Lawfoniana. In doing fo we have 
been influenced a good deal by the reported fragrance of the wood, as we have found the odour of Conifers 
a mofl: ufeful adjunfit to other more eafily expreffed fpecific characters. 
C. Lawfoniana as yet has given no particular indication of fragrance. Should it, when older and 
more mature, turn out to poffefs the fame odour as that of Dr Killog’s fpecies, we fhould then confider 
the 
* For convenience of comparifon we here give Mr Killog’s fcientific defcription: — “Branches four-fided, fomewhat compreffed, denfely 
crowded, fubdivifions numerous, with a frond-like arrangement, larger branches roundifh, nightly compreffed, laterally flexuofe. Bark madder 
brown, leaves diamond-acute, and aculeate, fhining bright vivid green, carinate, an oblong refinous gland along the back, adpreffed, imbricated 
in two rows; older leaves on the intermediate branches long, decurrent; point awl-fhaped, incurved. Cones pedicilate on long fcaly foot- 
ftalks, fimilar to the branchlets, fomewhat elongated, globofe, cinnamon colour, fize of a hazel nut, compofed of about nine peltate fcales. 
Centre depreffed : margin thickened and rounded, difc corrugated and rough ; a fharp tranfverfe ridge divides it fomewhat above the centre, the 
mucro broad, thin, or flat pointed, fragile, curved outwards, and pointed towards the apex, fcales irregularly five-fided. Seeds broadly winged all 
round, waved, oblique fcooped : bafe of the fmooth cylindrical kernel portion prominent, apex emarginate, mucronate, bright cinnamon colour.”
