Tnis species is a native of Mexico, Avhere Ilartweg discovered it on Mount 

 Cainpanario, growing at an elevation of 0000 feet, and ranging irnniediatcly 

 above Picea religiosa. It forms a tree of moderate size, with leaves six inches 



Pinus Hartwegi. 



and upwards in length, of a pale green, and covered with a glaucous bloom. 

 Although this Pine belongs to the five-leaved section of Pinus, it is often found 

 with four only in a bundle. The cones are four to five inches long, and pendulous. 

 Many of the species in the group to which Hartweg's Pine belongs are remark- 

 able for the length of their leaves ; and this, there being five in a sheath, gives 

 them a peculiar and striking appearance, and as such they are much prized by 

 collectors. Unfortunately the winter of 1853-4, and the following one, proved 

 fatal to many of the handsomest kinds, and they may be pronounced too tender 

 for the English climate. Of this section, we lost from our collection leiophylla, 

 Wiucesteriana, Gordoniana, filifolia, Russelliana, Devoniana, Grenvilleae, and 

 even palustris (australis) ; while Hartwegi, Montezuraee, and apulcensis of the 

 long-leaved species survived. And we find pretty nearly the same results 

 happened in other Pinetums. This greatly enhances the value of those which 

 have turned out to be hardy ; among them Hartwegi — which is now the finest of 

 the long-leaved species, capable of enduring our winters, excepting, perhaps P. 

 microphylla. 



No collection of Coniferae can be called complete except it contains our present
