ciated with plants such as Hierochloe odorala, Poteniilla anserina, Ranunculus repians, 

 Scirpus alpinus var. oUganthus, in incipient flowering at the beginning of June. 



Owing to the fact that this plant grows under rather different edaphical conditions, 

 in very saliferous to completely saltless, apparently generally sandy soil, there is a pos- 

 sibility that the plant may be influenced by this circumstance. On account of the 

 scarcity of my material, with too inaccurate records of situations, I have not been able 

 to perceive any regularity in this direction. 



In conclusion I may add that in the herbarium of the University at Christiania I 

 have seen a couple of specimens „Ex. Herb. Ind. Or. Hook. fil. et Thomson, Hab. Lada- 

 bele". Even in point of habitus these specimens differ rather much from the above- 

 mentioned 2 types, the leaves being long and narrow, generally several times as long as 

 broad. Some are completely entire and lanceolate, and others furnished with some few 

 teeth near the summit. These specimens also differ in the shape of the petals. Fig. 89, 

 u— X, representing petals from two different specimens, show that the lamina is oblong 

 elliptic, equally broad, obtusely rounded at both ends. My material, however, is not so 

 extensive as to enable me to examine the constancy of these characters. There remains 

 a possibility that the specimens in question may have to be entered as a third distinct 

 species, distributed over south-western Asia, and that future examinations will establish 

 the original Ranunculus Cymbalaria Pursch to comprise several well defined species, 

 both systematically and in point of geographic distribution. I might especially draw 

 attention to the more isolated occurrences, such as those in South America and the 

 above-mentioned Indian specimens. 



In alpine situations and in northern regions, Ranunculus Cymbalaria occurs under 

 a slightly reduced form, var. alpina, recorded from Asia as well as from America. I have 

 had no opportunity of examining it.

Rather common on the Abakan Steppe, at Ust Kamuishto, on saliferous soil, accom- 

 panying Lepidium crassifolium, Potentilla anserina. Primula longiscapa, Plantago mari- 

 tima, and Triglochin palustre. In full flower in the second half of June. The leaves of 

 the specimens collected are but slightly, nearly imperceptibly toothed. 



Distribution: Southern Siberia from the Altai region, eastwards to Trans Baikal 

 Mongolia, northern China.
