THE VARIATIONS OF PRIMULA FARINOSA IN 
NORTHEASTERN AMERICA. 
M. L. FERNALD. 
Primula farinosa in its broad sense is a plant of very wide range, 
the typical form occurring in northern and mountainous districts of 
Eurasia and North America, while some representative of the species 
is found in nearly all cooler parts of the globe, even in Antarctic South 
America. The plant of eastern North America is very generally 
called true P. farinosa, and in Engler's Pflanzenreich nearly all the 
American plants are united by Pax and Knuth with the Eurasian 
plant as P. farinosa, subsp. eufarinosa Pax, var. genuina Pax! As 
shown in the Gray Herbarium, however, there is very little American 
material which is clearly identical with the Eurasian type of P. farinosa. 
Instead, most of the material from the northeastern United States and 
adjacent British America is of two seemingly endemic varieties, while 
in the Rocky Mountains is a third which may be looked for with some 
confidence on the mountains of eastern Quebec. ‘These three varieties 
and the Eurasian type of the species may be distinguished as follows. 
* Calyx in anthesis 3-5 mm. long; involucral bracts 3.5-6 mm. long. 
P. rartnosa L. Low, rarely 3 dm. high: leaves oblanceolate to 
narrowly obovate, white-farinose beneath: bracts lance-attenuate: 
pedicels rarely equalling the calyx: capsule 6-8 mm. long, slightly 
exserted.— Sp. i. 143 (1753).— Eurasia. Rare in America: examined 
only from Labrador.and Newfoundland. 
Var. AMERICANA Torr. Scape 1-2.5 dm. high: leaves oblanceolate
