his statement, there is all the reason to claim that the two species 

 are there published as Apimis. Necker states that Larix contains 

 3 species, z//>..- decidua, cedriis and strobu^ ; Pinus 2, sylvestris and 

 taeda : Apiniis also 2, viz.: cembra and pinea, but Abies 5, etc. If 

 Necker had meant that these were the Linnaean species of Pimis 

 to be distributed among the different genera, he would have stated 

 it differently. There was no Pinus decidua L,, but a Pinus Larix 

 L. and a Larix decidua Miller. Apimis is most related to Strobns, 

 but differs in the thick cone-scales, the erect or horizontal instead 

 of pendent cone and a very hard-shelled seed with only a vestige 

 of a wing. In the Rocky Mountains, it is represented by the two 

 following species :

 up by Dr. Small. I shall here give only the Rocky Mountain 

 species to be referred to this genus.
