raising this form of pine to the rank of a species, dedicating 

 it to the discoverer as Pinus Murrayana. 



The true Pinus conforta, divested thus of its near relative, 

 consists mostly of the form on the coast of which some char- 

 acters have been given, but others must now be stated. The 

 leaves and cones exhibit an unprecedented disposition to sport 

 or vary in many directions, this variability seems to have no 

 relation to location or condition, widely diJBferent leaves and 

 cones being found not only upon trees of the same grove, but 

 upon limbs of the same tree. The leaves vary widely 

 (especially on Alaskan trees) while the cones on certain trees, 

 or on certain limbs, are two and one-half to three inches loug 

 and an inch wide near the base ; on other trees or other limbs 

 they are but an inch long ; but whatever the size there is an- 

 other point of variability, prevalent in the development of the 

 scales. Normally, they are nearly flat, with low apophyses 

 and short slender prickles (as originally described by Lou- 

 don), but often the cones are conspicuously tuberculated, the 

 basal scales on the exterior side being specially developed 

 with conical apophyses and strong prickles. Often these 

 specialized scales extend all along the outer side of the cone, 

 and again, they may occur only at the apex. Upon trees of the 

 interior regions this variation is unknown, all the cones are 

 nearly uniform in size and all have slightly elevated scales on 

 the exterior base. 



Var. Bolanderi. The little dwarfs on the Mendocino 

 Plams described, though similar to the typical form, 

 are still quite peculiar in respect of small size in all their 

 parts, besides in the general form of the trees, being conical 

 instead of round-headed, and the color of the foliage being 

 lighter, and the bark thinner. This strongly marked variety 

 may well bear the name of its discoverer, ^
