598 Rydberg : Rocky Mountain flora 



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

 are there published as Apiiiiis. Necker states that Larix contains 

 3 species, 7^/^./ decidua, cedriis and strobus ; Finns 2, sylvestris and 

 tacda : Apimis also 2, viz.: cembra and pinea, but Abies 5, etc. If 

 Necker had meant that these were the Linnaean species of Pinus 

 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. Apinus is most related to Strobus, 

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

 of pendent cone and a ver)^ hard-shelled seed with only a vestige 

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

 following species : 



Apinus flexilis (James) Rydb. 

 Pinus flexil is ]2im&s, in Long's Exped. 2: 34. 1823. 



Apinus albicaulis (Engelm.) Rydb. 

 Pinus albicaulis Engelm. Trans. Acad. St. Louis 2 : 209. 1863. 



Sabina utahensis (Engelm.) Rydb. 



Juniperus calif arnica utahensis Engelm. Trans. Acad. St. Louis 3 : 



588. 1877. 



Haller's genus Sabina is also one just as consistently taken 

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

 species to be referred to this genus. 



Sabina monosperma (Engelm.) Rydb.

Sabina Knightii (A. Nels.) Rydb.
