than the style. These well-developed carpels, however, cannot be taken for absolute 

 proofs against a hybrid nature, for there are instances that authentic bastards of 

 Potenlilla may give well-developed carpels. In my opinion, such specimens as those 

 described may as well be explained as an evidence of the near relationship of Potenlilla 

 lernata to P. fragarioides — as intermediates between them — and it would therefore pos- 

 sibly be as right to enter our plant under Maximowicz's name as Potenlilla fragarioides 

 var. iernata. 



Occurring in thickets and meadows on the islets iiY the Yenisei, between Minusinsk 

 and Ust Abakansk, where the specimens are mostly past flowering at the beginning of 

 June. 



Distribution: Potenlilla lernata is previously known in the Amoor Province, eastern 

 Manchooria, the Ussuri Province, Japan.

Pretty common in moist meadows in brush-wood, and the like, on an islet in the 

 river Abakan, near Ust Kamuishto, where I have collected it in flower and partly past 

 flowering at the end of June. It also occurs in the Urjankai country, in humid grass-fields 

 on the banks of the Ulu-kem, at Bjelosarsk, and near Cha-kul. 



Distribution: Temperate portions of Siberia, northern Mongolia, Manchooria, north- 

 ern Corea, northern China.

Scattered about Kushabar where found be me on dry hills with flowers at the middle 

 of July. 



Distribution: Europe, Caucasia and south-western Asia, Siberia, eastwards to about 

 Lake Baikal, northern Mongolia, North America (introduced).

Very common in the territory explored, where occurring under a great many different 

 forms. In the Minusinsk district it is very common along banks of rivers, etc., and on 

 saliferous soil at Ust Kamuishto. Among the material collected the following forms may 

 be separated: vulgaris, sericea, incisa, discolor, and tenella. In the Altaian, near the tree 

 limit I have found specimens of a form much recaUing /. grandis. Collected in full 

 bloom from June to August.
