at over 6,500 feet it is hardly more than a shrub, and forms dense 
thickets. The arbor vitae, the red cedar of Oregon {Thuya giganiea^

feet in diameter.

were seen at low elevations. The main summit of the Cascade Range, 
in the region where the above observations were taken, has an alti- 
tude varying from 6,000 to 6,800 feet, and is generally bare of timber. 
Its immediate slopes are covered with grass and flowers of every hue 
interspersed with bunches of willows and groves of fir.

Fasciation in Rubus.— A curious case of fasciation was brought 
to my notice a short time since. The specimen was a cane of the 
cultivated black-cap raspberry, which, at the extremity, had become 
strongly flattened and coiled upon itself in the form of a flat spiral. 
The width of the cane was seven-eighths of an inch, and the thick- 
ness about one-third of an inch near the outer circumference of the 
coil, while on the inner side it was much thinner. The four com- 
plete coils were from one and one-half to three and one-half inches 
across. From the beginning of the first coil the cane bore an un- 
usual number of abortive foliar organs, which increased in number 
toward the extremity until the entire tip was of a thickened and 
foliaceous character. 
A cross-section of the cane showed it to consist of two regions 
of entirely different tissue. The thickened portion which followed 
the periphery of the curve was of normal woody structure, while the 
opposite side was composed almost entirely of parenchyma. This 
differentiation of tissues, with their unequal rates of growth, doubt- 
less explains the phenomenon of curving. The coil became more 
distinct and its radius shorter as the difference between the two 
regions became more marked, until, at the extremity, the paren- 
chyma predominated and expanded into a sort of flattened mem- 
brane. At the time of collection the woody region was still fresh 
and active, but the parenchyma was dead and withered. This, no 
doubt, assisted in the curvature, since several transverse fissures 
across the parenchyma showed that it had been subjected to con- 
siderable tension. 
I believe the cultivated species of Rubus are especially liable to 
oddities of growth, but I have never seen so striking a departure as 
this before.

Genus Labels.— Mr. H. N. Patterson, of Oquawka, 111., desires us 
to state that the first box of his North American genus-labels, from 
Ranunculace^e to Compositse, 650 genera (3 of each), is now ready 
for delivery. Frice $1-30. 
Note. — We send out with this number three plates, which are to 
be substituted for the badly printed ones that accompanied our 
March issue.
