has prevailed with regard to the hark of the two species. Loudon's description was inspired hy 

 Hartweg's recent collections in Mexico and probably by such information as he sent with them. Probably Loudon's 

 description of the bark was copied from Hartweg. Hartweg's specimen No. 442 (Bentham, PL Eartw. 58), and all 

 specimens with patula like cones and short erect leaves, are probably Pimis Greggii. 



A specimen at Berlin labeled Pinus Greggii is apparently correct as to the leaves, but the cones so labeled in 

 another part of the museum belong to another species. 



The figure from The Gardener's Chronicle, quoted above, is from a tree cultivated by the brothers Rovelli at 

 Pallanza, in Italy, under the name Pinus del Doctor, or Pinus subpatula, Roezl. These are both unpublished names.
