This is a distinct variety with the smallest leaves as well as the smallest flowers, 

 which are generally arranged in a racemiform cyme or thyrsus. The length of the 

 corolla including the tube is only about 15 mm. According to Herder (PI. Radd. 

 1. c. p. 199), Regel once gave to the plant the name, var. parvifloruin, which is 

 probably more appropriate than his published name, var. vulgare, lusus racemosum. 

 The diagnosis given by Regel for the plant, though brief, is so well delineated, that 

 we do not hesitate to include our forms from Kushiro and Saghalin, and also those 

 from the Amur- and Ussuri-regions under the one and same variety. 



In the specimens collected at Shikka in Saghalin, the lobes of the corolla are 

 mucronate at the apex, although in other characters we could not find any point 

 of difference from the present variety. 



In one of the specimens collected in Kushiro, all the flowers are provided with 

 a 4-lobed stigma. Such an anomalous case has already been observed in some species 

 of Phlox and Gilia, but as far as we know, the fact is new in the genus Polemoni- 

 um.
