Pretty common in moist 

 meadows and in open brush-wood 

 on islets in the river Abakan, near 

 iVsliys, and at Ust Kamuishto. On 

 the islets in the river Abakan, near 

 Askys, I have collected a small- 

 leaved form, in which the leaves 

 are only 4 — 6 mm. broad, and 5 — 

 6 times as long, always 1-nerved 

 only. Flowering in the middle of 

 June. Near Ust Kamuishto I have 

 collected some specimens of a 

 more broad-leaved form, the lea- 

 ves of which are 12 — 15 mm. 

 broad, and about 3 times as long, 

 always furnished with 3 distinct 

 nerves. Of this one I have found 

 young, not yet flowering speci- 

 mens at the end of June. The spe- 

 cies also occurs in the Urjankai 

 cotmtry, where collected by me on 

 flood-plains at Ust Tara-kem. 



Distribution: From the Ui'al 

 eastwards through Siberia toKamt- 

 chatka and the Amoor Province, 

 northern Mongolia, Manchooria, 

 northern China, Sakhalin, Japan.
