A. LASIOCARPA, CONCOLOR, AND PINDROW 9§ 
practically sessile. They are—the cones—hard to 
get and bad travellers, and some—at least so I have 
found—of the hardest to obtain. The sharp-pointed 
head of the tree in its native land, which seems to 
run its course from Yukon to Colorado, makes it a 
conspicuous object for recognition to all residents 
versed, and travellers interested, in the ways and 
habits of the trees of the country. 
The moral of this description is that when you 
notice a tree labelled Lasiocarpa or Subalpina in a 
nurseryman’s garden, and it answers all these de- 
scriptions, and only when it does, get out your pen 
and write an order. 
A. ConcoLor has been dealt with in connection 
with the A. Lowiana, under the head Group II. It 
seems curious that two such closely related affinities 
of, moreover, a perplexing similarity of appearance, 
should be found herded in different pens. 
Some authorities even include both the Colorado 
(A., Concolor) and the Californian tree (A. Lowiana) 
in the same name Concolor, and the same authorities 
upon the question of relative hardness pronounce a 
judgment in favour of the Colorado Concolor. 
Concolor is a Latin word meaning “‘ of the same 
colour’; why it was so called by Engelmann, history 
does not appear to relate, or perhaps crassness of 
intelligence fails to enlighten. It was introduced in 
the early seventies, or some twenty years after the 
appearance of the A. Lowiana. 
A. PinpRow.—We have alluded to this tree in 
connection with its affinity, the A. Webbiana. Here 
again we might have expected the two to have been 
accommedated in the same compartment under a 
group system. At the same time there are several 
very obvious differences that meet the eye of the 
identifier readily.
