Although we have followed here the monographer Brand in the nomenclature 

 of this plant, yet we could not help thinking that the present subspecies may be 

 worth afttr all of a specific rank, especially when we examine a large series of 

 specimens collected from the regions around the Behring Sea, the original home of 

 the plant. An acute deltoid tip of the corolla-lobe and shaggy-liaired calyx are 

 very characteristic. The corolla-lobes, as they fade in color, often leave behind 

 deeper colored spots giving to them a fine punctate or mottled appearance. The 

 last mentioned character is also observable in the Saghalin specimens. 



Brand seems to have considered the Saghalin Polemonium to be entirely of 

 this type. The examination of a large number of specimens collected by Älessrs. 

 T. Miyake, T. Miyagi and one of us in different jiarts of Saghalin shows an inter- 

 esting fact, that tlie villosum-type is localized around a small area in the central 

 portion between Mauka and Vladimilovka. The most common form in Saghalin, 

 as has already been stated, i.s of the var. laxiflorum, and next to it the var. 

 racemosum.
