302 Capt. S. E. Cook on Pinus and Abies. 



as the appearance of the foHage, which is more dark in co- 

 lour, and stronger in the spiculae, which stand out in a pecu- 

 Harly rigid form hke the spokes of a bottle brush, if such a 

 comparison may be used*. Those which were brought to this 

 country by me were chiefly from the forests of the Spanish 

 Pyrenees, which are still of vast extent, very few trees now 

 existing on the French side. 



I have no doubt that the Mughus of the catalogues is 

 synonymous with the uncinata, and if the species, as there 

 is reason to believe, occurs on Mount Cenis, it is probable 

 that uncinata has been applied to the Pyrenean and Mughus 

 to the Alpine tree. 



P. Pumilio is completely distinct from either Mughus or un- 

 cinata, with both of which it has been confounded. It is de- 

 scribed in the French books as being found in the"Marais tour- 

 beux du Jura.^^ I have never seen it in any part of the Jura I 

 have visited, but from the difficulty of establishing it in hard 

 ground it is probably the case, and I have heard that it exists 

 in Hungary. There are two varieties, one red and the other 

 white in the flower, both which may be seen in great beauty 

 at Dropmore. The peculiar habit of the tree is to trail on the 

 ground and extend itself laterally, the branches being curved 

 upwards ; the cone is small and something like that of P. un- 

 cinata. 



In assigning the species which have come under my obser- 

 vation in this and in the preceding paper, the cones and fruc- 

 tification are the points principally attended to. I have 

 given the characters as clearly as I could commit them to pa- 

 per. There are others as to the port and bearing of the trees 

 which can only be fairly judged by much practice and the ha- 

 bit of seeing the trees in their native forests and in masses, 

 where both species and individuals are fully developed. 



* It is quite erroneous to suppose that individuals with these characters 

 are to be found in the common woods of sylvestris, as any one may satisfy 

 himself by visiting a forest of this species and studying the foliage and form 

 of the trees.
