This group is almost exclusively Mexican ; it is of recent introduc- 

 tion, and as most of tlie species are somewhat tender, more time must 

 elapse before their general habits can be accurately known. The Bot- 

 anists who introduced tliem do not seem to have paid much attention 

 to the forms of the trees ; but as far as can be judged at present, they 

 arc likely to approach the rounded cone, or an irregular, broad, loose 

 habit The branches of 106 and 113 are large and iiregular; of 107, 

 numerous in whorls ; and of 109, few, strong, irregular, and spreading. 

 The foliage in 100, 107, 112, and 114, is of a liglit green ; in 102, 103, 

 104, 105, 109, 111, it IS glaucous; and in 106 it is of a dark-green color. 

 The leaves of all the species are extremely long ; in P. Deconianu and 

 Wincesteriana they are from 12 to 14 inches long ; and in P. macrophylla 

 and Gordaiuana about 15 or 16 inches long. The timber of 112 is val- 

 uable. The curious, tressy, light-colored foliage of this group makes 

 it very desirable for ornamental purposes. The value of the timber 

 generally has not yet been well ascertained.
