GENERIC JiJAME OF J^HE WHITE FINE 6(/ 



Small" in his Flora of the vSoutheastern United .States. The 

 generic name Slrobus accepted by that author is objectionable 

 not only for the reason shown above, but it is a homonym to 

 Sirohon Raf.,' and apparently neuter gender form of a noun 

 of similar appearance, and certainly more like Slrobus than the 

 Galcaris he objects to resembles Galearia^ Historical priority 

 being the rule followed in the "Notes" this problem did not really 

 concern us, yet it is worth while to point out that even assuming 

 1753 as the "starting point" for botanical nomenclature, Slrobus 

 is still inadmissable as a generic name for the White Pines. 



We were also aware that Apinus Necker^ demanded consid- 

 eration, but a curious confusion presents itself here for which at 

 first we were unwilling to suggest a solution or propose a definite 

 opinion. Necker seems to have proposed the name Apinus for 

 the "group" containing Pinups Cembra Linn, and Pinus Pima 

 Linn. Pinus Slrobus Linn, itself is by him actually put under 

 Larix^' and therefore positively excluded from Apinus. Under 

 these circumstances we can scarcely see hf)w Pinw; Slrobus could 

 be put in a genus from which the very author thereof himself 

 deliberately excludes it, whatever there be in description that 

 might perhaps allow it therein. Since therefore Slrobus is a hom- 

 onym there seems nothing to do, if the White Pines are a valid 

 genus, but suggest a new name for them, and we propose Leucopitys 

 The word comes from the Greek '/jvxoc., white, and TiiTvg, pine. 

 A description of the generic characters is scarcely necessary after 

 considering those given by Small. ^ Following is the synonymy of 

 the two most characteristic species.
