 river. Partly done flowering at the end of June.

? Oxytropis ammophila Turczan. in Bullet. Soc. Natural. Moscou (1840) p. 66; 

 Ledeb. Fl. Boss. I, p. 595. 



On the Abakan Steppe I have collected a rather rich material of a species of 

 Oxytropis, which — not without having ray doubts, however — I have referred to 0. 

 ammophila, the specimens being too young for a reliable decision. This plant is very 

 common on the steppes between Minusinsk and list Abakansk, where being a characteri- 

 stic plant in dry, sandy places, together with Thermopsis lanceolata, Onosma echioides, 

 etc. Collected with flower-buds and young flowers in the first half of August. During a 

 stay in Petrograd, Prof. Dr. B. Fedtschenko, the noted student of Leguminous plants, 

 declared my determination to be very probable. 



Distribution: Southern Siberia (the government of Yeniseisk).

In point of external habitus our plant differs rather much from the typical species, 

 chiefly owing to the long, vigorous scape, while in Bunge's authentic specimens, which 

 I have seen in the herbarium of the Imperial Botanical Gardens in Petrograd, however,
