210 DR. W. R, M'NAB ON ABIES PATTONLI, 
Committee seems to have accepted Jeffrey's determination 
without examination *, and printed the description of the Mount- 
Baker tree from lat. 44? N., and sent it out with the seeds of 
no. 430 from lat. 42? N. My late father was cognizant of this; 
and in his paper in the Transactions of the Bot. Soc. Edin. vol. xi. 
p. 327, says, “Abies Hookeriana was sent by Jeffrey at the same 
time ” as Abies Pattoniana. The examination of the structure of 
the leaves and of the cones of Jeffrey's no. 430 demonstrates that 
the plant is that afterwards figured and described by Murray as 
A. Hookeriana. The confusion of the plants thus originates with 
Jeffrey himself. Professor Balfour's description of A. Pattoniana 
was printed in 1853 in the Circular of the Oregon Committee, 
for the private use of the Members of the Association; and the 
specimens described are evidently Jeffrey's no. 430, and not the 
plant of 1851 from Mount-Baker. 
In 1854 Mr. William Murray discovered a Pine on Scot’s 
Mountain, lat. 419 20' N., which was described in 1855 by Mr. 
Andrew Murray in the ‘ Edinburgh New Philosophical Journal ’ 
(April 1855) as Abies Hookeriana. Cones of Murray’s plant in 
the museum of the Edinburgh Garden are the same as those of 
Pattoniana, Balfour, in the same collection ; and although Murray 
gives different figures of the braet of the two forms, I have 
not been able to find any cone with the braet corresponding to 
his figure of what he calls 4. Pattoniana, Balfour. Moreover, 
Murray does not state whether the bract figured is from a Mount- 
Baker or Cascade- Mountain specimen, a most important omis- 
sion. We are now prepared to find Carrière, Parlatore, and 
others uniting the two supposed forms described by Balfour and 
Murray, as they are simply one and the same thing. 
In 1863 Mr. Andrew Murray, in his *Synonymy of various 
Conifers,’ p. 14, pointed out that the leaves of Jeffrey’s Mount- 
Baker plant and those of 4. Hookeriana from Scot's Mountain were 
quite different, a character on which my late father always insisted. 
The leaf of 4. Pattoniana is flat and serrate at the tip, while that 
of 4. Hookeriana is entire and more quadrangular, Murray's 
figures 16 and 17 showing the difference admirably. The plants 
are here for the first time properly separated, by characters 
derived from the leaves only, the cone of Jeffrey’s Mount- Baker 
plant never having been figured. 
Parlatore, in DeCandolle's * Prodromus, evidently combines 
* Murray, loc. cit. p. 15.
