598 Rvdberg : Rocky Mountain flora 



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

 are there published as Apinus. Necker states that Larix contains 

 3 species, viz.. ■ decidua, cedrus and strobus ; Finns 2, sylvestris and 

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

 Necker had meant that these were the Linnaean species of Finns 

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

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

 L. and a Larix decidua Miller. Apinus is most related to Strobus, 

 but differs in the thick cone-scaies, 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 : 



Apinus flexilis (James) Rydb. 

 Piuus flcxilis James, in Long's Exped. 2: 34. 1823. 



Apinus albicaulis (Engelm.) Rydb. 

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



Sabina utahensis (Engelm.) Rydb. 



Junipcrus californica 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. 



Junipcrus occidentalis monosperma Engelm. Trans. Acad. St. Louis 

 3: 590. 1877. 



Sabina Knightii (A. Nels.) Rydb. 

 Juniperus Knightii A. Nels. Bot. Gaz. 25: 198. 1898. 



Sabina scopulorum (Sargent) Rydb. 

 Juniperus sco pulorum Sargent, Garden and Forest 10 : 420. 1897. 



Sparganium multipedunculatum (Morong) Rydb. 



Sparganium simplex multipedunculata Morong, Bull. Torrey Club 

 15: 79. 1888.
