In 'ki. Maiii.<r,i,ypiii III (1907), the excellent work on the vef,'elalion of eastern Asia, 

 KoM.xnow identifies this species with the American H. larxiliiin Mk.iix. (I'M. Hor. .\mer. 

 18();i, p. !()()), agreeing with M.wimowicz, who has examined this group of Hcniclciim in 

 point of nionography. Moreover, he refers as synonyms of this species: //. harbnliiin 

 Li;i)KH., H. (hilve Fiscuku. and H. MocllriKhiffii II.wci;. However, as I waid suffieieni 

 material for enabling me to form any opinion whellier tins be right. I have chosen to 

 enter the species here under I,i;i)i;iu)t n's earliest name given to liie |)lanl peculiar to the 

 interior of Asia. 



The species is pretty common in meadows and in copse wood on i.slels in the river 

 Abakan, where I have collected it with young flowers at the end of .lune. It is also rather 

 fre(pient about Kushabar, and in the subalpine tracts about Ihe I'jjpei' .Vmyl, moreover, 

 in the Urjankai country, about the basins of the rivers Algiac, Sisti-kem, Kamsara, and 

 Tara-kem, where, in places, covering glades,and the like, over large tracts. In the Altaian 

 it ascends to about the tree limit. 



Distribution: Siberia, in the Yenisei valley northwards to past 70 north lat., and 

 eastwards to the Amoor Province. Kamtchatka. Turkestan and northei-n Mongolia, Sakha- 

 lin, Japan, Corea and China. If. conformable to Komahow. 1. c. it is to be identified with 

 H. lanalnm, there must .still be added to its geographical range: North America, south- 

 wards to about Utah.

Near Kushabar, in meadows, and at Ust Algiac, Ust Sisti-kem and I'st Tara-kem. in
