288 Andrew Murray's Description 



gives a false impression of the direction of the umbo. There 

 can be no doubt about this, because my brother found all 

 Hartweg's localities so strictly correct that he could recognise 

 the very patches of different trees that he describes having 

 met ; and he took his observations on the cones, &c. of Ben- 

 thamiana from the very clump of that tree described by 

 Hartweg, as found by him near Santa Cruz. There was n# 

 other tree, or clump of trees, for a great distance, with which 

 it could be confounded. 



There is also some resemblance between this Pine (Beards- 

 leyi) and P. ponderosa, as was well suggested to me by Dr 

 Lindley ; but the shape of the cone, and the size and shape of 

 the seed and wing sufficiently distinguish it. In P.ponderosa 

 the cone tapers to both ends, while in this it tapers to the 

 point. Its seed does not appear to be speckled in any figure 1 

 have seen (I have not seen any specimen of the seed itself), 

 while this is. The sheath of the leaf in P. ponderosa is smooth 

 longish, fine, and tightly fitting, whereas in this it is short, 

 corrugated and rough ; and the leaf of ponderosa is nearly 

 twice as long, being 9 to 11 inches in length, in place of 6 

 inches. Its leaf also wants (or nearly so) the projecting points 

 which roughen that of Beardsleyi, so that the leaves can be 

 distinguished by the feel, or drawing them forwards between 

 the fingers,

 on the outer and inner side, those on the outer being rather 

 more developed, but it is not very marked. Scales an inch
