PINACE.^. 



a sandy loam, or gravellj^ earth, with a sandy, gravelly, or porous sub- 

 soil. Generally, when young, and when grown singly, they are 

 regularly furnished with branches to their base ; but when old, and 

 thoroughly matured, particularly when grown in groups or masses, the 

 under branches die off gradually, as the trees increase in age, so that 

 eventually they are generally clear of branches for one half or two- 

 thirds their height ; having conic, rhomboid, spreading, or umbrella- 

 like branched heads. 



PiNUS AlbigUALIS : An Alpine S]jecies from the Cascade 

 Mountains in Oregon, may be a western form of the Cembra-like 

 Pine, though I am inclined to consider it as different, and intermediate 

 between Pinus Flexilis (even this is not a species, but a qnSi^i-Cembri- 

 PineaJ ; and Cembra distinguished by its pubescent branches, few 

 scattered teeth on the edges of the leaves, and especially by the short, 

 oval cones, with squarrose scales, pointed with a knob. The name is 

 suggested by the colour of the bark of the tree, which is " as white as 

 milk.'" Englemann in Trans. Accd. Sc. of PhiladeJjjhia. 



'Cute suggestion this, of Dr. Englemann, but rather more transparent 

 than milh^'^ and of a different colour than icliite^'' at least to a 

 practical cultivator. He might quite as appropriately have suggested 

 hlue as milk and water for the bark of his thought-to-be neio^ but, 

 indeed, very old Pine — the quasi of quasi Camljroides. 



Be tliis as it may, however, this is the way in which too many of 

 our said or thought-to-be new Pines are introduced to us, and fully 

 illustrates my prefatory remarks on the genus Pinns. 



All that can be said of this Pine in this book is that a variety it 

 certainly is, a species it certainly is not ; a quasi-species it may be ; 

 but at best only useful for adding numbers to, and increasing the inef- 

 fable variety of an already large or extensive pinetum. 



PmUS ApULCENSIS : The Apulco Pine. 



This was introduced to us from Mexico in 1839. A small-sized tree, 

 thirty to fifty feet, with robust branches irregularly disposed, and on 

 young growths of a glaucous violet colour ; leaves from five to seven 

 inches long, generally five in a sheath, slender, undulating, and of a 

 rich and deep glaucous green ; its cones are ovate, three to five inches 

 long, and about half as broad as long. Its wood is Avhite, soft, and 

 porous. It is somewhat too delicate and tender lor the climate of 

 Britain, and is of no use but for adding number and variety to a 

 pinetum, the soil of which is a good loam, and the locality of which is 

 warm, and the situation assigned to this Pine a well sheltered one.
