A. LASIOCARPA, CONCOLOR, AND PIXDROW 95 



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 mclude 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. PiNDROW. — We have alluded to this tree in 

 connection with its affinity, the A. Webbiana. Here 

 agam we might have expected the tw^o to have been 

 accommodated in the same compartment under a 

 group S3^stem. At the same time there are several 

 very obvious differences that meet the eye of the 

 identifier readily.
