This group is abnost exclusively Mexican ; it is of recent introduction, 

 and as most of the species are somewhat tender, more time miist elapse 

 before their general habits can be accurately known. The Botanists 

 who iatrodueed them do not seem to have paid much attention to the 

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

 Hkely to approach the rounded cone, or an irregular broad loose habit. 

 The branches of 106 and 113 are large and irregular ; of 107, numerous 

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

 in 100, 107, 112, and 114 is of a hght green ; in 102, 103, 104, 105, 

 109, 111, it is glaucous ; and in 106 it is of a dark green colour. The 

 leaves of all the species are extremely long ; in P. Devoniana and Win- 

 cesteriana tliey are from 12 to 14 inches long ; and in P. macrophylla 

 and Grordoniana about 15 or 16 inches long. The timber of 112 is 

 valuable. The cmious, tressy, light-coloured fohage of this group makes 

 it very desirable for ornamental pm'poses. The value of the timber gene- 

 rally has not yet been well ascertained.
