Very common on sandy steppes between Minusinsk and Ust Abakansk, and also here 

 and there on rocks on the Abakan Steppe. The species begins flowering here at the begin- 

 ning of June. Also observed past flowering on dry southern slopes, near Ust Kamsara, 

 and on the steppes about the Ulu-kem at the end of August. The plants nearly always 

 beset with one or several specimens of the Spanish fly [Lytta caraganae Pall.). 



Distribution: South-eastern Russia, Russian Turkestan, southern Siberia to Trans 

 Baikal, northern Mongolia, northern China.

By the road between Kushabar and Karatus, near the banks of the river Amyl, in 

 the transition zone between the steppes and the wooded region. Collected in slightly 

 moist, grass-grown thicket, with flowers and young fruits in the middle of July. Taken 

 with ripe fruits near Ust Sisti-kem and on wood-steppes at Ust Tara-kem in the middle 

 of August. 



Distribution: Southern Siberia, eastwards to the government of Irkutsk, Russian

The material collected shows considerable variations as to shape and size of the 

 leaflets, pubescence of the plants, floweriness, etc. The shape of the leaflets varies from 

 nearly ovate to very oblong, about 6 times as long as broad. The subulate, mucronulate 

 stipules are partly entire, partly serrulate at the margin. The raceme rather flower^', ge- 

 nerally containing 8 — 14 flowers. Length of the fully developed flowers 10 — 12 mm. Of 

 very common occurrence on the Abakan Steppe and on the islets in the lower part of 

 the river, in open, sunny places, on stony declivities, in dry, sandy and stony grass- 

 field, etc., where I have collected it with young flowers and flower-buds in the fii'st 

 half of June. It is also scattered on the road between Karatus and Kushabar, at Ust Sisti- 

 kem, and on the steppes about the Ulu-kem. 



Distribution: Europe, except the extreme north, the Caucasus, Siberia, northwards 

 to about 60° north lat., and eastwards to Trans Baikal, Mongolia, northern China, 

 south-western Asia to Afghanistan and Turkestan, the East Indies.

In meadows on islets in the river Abakan, near Ust Abakansk. Collected with 

 young flower-buds at the end of June. In the Urjankai counti-j' I have collected the species 

 on dry hills near Tapsa.
