specimens of it extant in these islands. There is a Microjyhylla, (small- 

 leaved,) likewise a Microcarpha, (small-coned,) variety of it. 



PiNUS FiLIFOLIA : The Thread-like-Leaved Pine. 



This was iatroduced from Giiatemala about twenty years ago. It 

 attains heights of from thirty-five to seventy-five feet, having few, irre- 

 gular, and stout branches, clothed with leaves of a dull green colour, 

 from ten to fifteen inches long, and cones from five to nine inches long. 

 It is somewhat too tender and delicate in constitution for the very best 

 soils and situations in which we have yet tried it here, in South Hants. 



PiNUS FlexILIS : The Contorted-Branched Pine. 



A said-to-be new species, from which I dissent ; it has been found 

 in California and Mexico ; and all that I have yet seen of its seeds, 

 seedlings, and young plants, shows it to be a quasi-species, which will 

 have to be classed with these now numerous quasi Cemhra-Pinea 

 kinds ; which are useful for nothing, unless indeed for making confu- 

 sion worse confounded, in the classification and nomenclature of the 

 Pines ; and this very Pine were it named Pinus Mutahilis, the vari- 

 able Pine, might be used as the representative of these quasi kinds of 

 Cembra and Pinea, inasmuch as it could be described : — Leaves 

 variable, from one to five inches long, light or dark green, in twos, 

 threes, fours, or fives, in a sheath ; stout or slender, curved or 

 straight. Cones ovate, oblong, or round, from one-and-a-half to 

 four inches long, and from one to two inches broad, having large seeds. 

 Branches horizontal, stout, and twisted, straight, or curved, and 

 ascending or drooping at their extremities. Tree from twenty-five to 

 fifty feet, or, when starved, reduced to a knarled bush a yard high, or 

 a big shrub, from one-half dozen to a dozen feet in height. 



PiNUS FrEMONTIANA: Fremont's Pine. 



This is merely a quasi of the preceding : having straighter, and 

 more regularly disposed branches ; a tolerably hardy, but very tardy 

 and slow growing nut Pine, with its leaves generally in threes, fre- 

 quently in twos, rarely in fives, exceptionally singly : and also from 

 California. 



PiNUS GeraRDIANA: Gerard's Pine. 



Introduced from the Himalayas in 1815, though it had been dis- 

 covered long previous to that date. It is a distinct Pine, remarkable 

 for its smooth silvery-grey bark, which, like Bungeana, peels off in 

 silken flakes. Its leaves are from two to six inches long, glaucous 

 when young, and bluish-green in colour : the cones are ovate in form, 

 from five to nine inches long, and from nine to fifteen inches in cir-
