DR. W. R. M'NAB ON ABIES PATTONII. 209 
recent examination shows that these cones were all of one spe- 
cies. The specimens in the museum and herbarium of the Edin- 
burgh Royal Botanic Garden have been examined; and through 
the kindness of Professor Balfour, F.R.S., I was permitted to 
obtain a set of type cones as well as a series of leaves for micro- 
scopical examination. In no case have I been able to obtain a 
cone of Abies Pattonü, Jeffrey MSS., all the cones examined 
belonging to one species, the plant known as Abies Hookeriana 
in the Royal Botanie Garden, Edinburgh. 
In 1851 Mr. John Jeffrev, the collector of the Oregon Associa- 
tion, sent home seeds of a Pine with the following description :— 
“ Found on the Mount-Baker range of mountains. This species 
makes its appearance at the point where A. canadensis * disap- 
pears, that is, at an elevation of about 5000 feet above the sea; 
from that point to the margin of perpetual snow it is found. 
Along the lower part of the range it is a noble-looking tree, rising 
to the height of 150 feet, 131 feet in diameter. Asit ascends the 
mountain it gets gradually smaller, till at last it dwindles into a 
shrub not more than 4 feet high. 
“ Leaves solitary, dark green above, silvery beneath, flat and 
rounded at the points, thickly placed round the branches; cones 
about an inch long, produced at the points of the branches, pen- 
dulous; bark rough, of a greyish colour ; timber hard and very fine 
in the grain, of a reddish colour. Soil in which this tree was 
growing most luxuriant was red loam, very strong and moist. If 
this tree proves undeseribed, I hope it may be known under the 
name of Abies Pattonüi.” 
Seedlings of this were raised in the Edinburgh Botanic Garden ; 
and there is now one good plant living in the Garden; but I 
have not been able to find any dried specimens or cones in the 
museum or herbarium. Jeffrey's description of the leaf is so 
exact, that the plant intended by him cannot be mistaken. In 
the next consignment of seeds from Jeffrey we have his no. 430, 
* Cascade "Mountains, lat. 429. Elevation 6000 feet. October 
15,1852." And Jeffrey adds (see Murray, ‘Synonymy of various 
Conifers,’ p. 15) :—“ I forwarded specimens of this species in case 
no. 3, and at the same time suggested that it should be named 
A. Pattoniana. Numerous specimens are extant of Jeffrey's 
no. 430; and all I have examined are, without exception, the 
species described by Murray as Abies Hookeriana. The Oregon 
* Probably A. Albertiana, À. Murr.
