 altis, ad basin lignosis, suffrUticosis, adscendentibus, inferne leviter superne altius 

 sulcatis, glabris vel leviter pilosis. Folia sessilia, impari-pinnata, 5-8 juga; foliola inferio-

The specimens of Astragalus sulcatusL. collectedbyme on the Abakan Steppe, near Ust 

 Kamuishto, differ in some respects so much from the typical plant that I have found it 

 necessary to enter it as a new subspecies. Already in 1842, Turczaninow, 1. c. called at- 

 tention to the fact that specimens of this one from Baikal differ from material from the 

 Altai by frequently having the wings indented. „Planta nostra ab Altaica parum recedit 

 alis plerunique emarginatis, sed in eodem individuo etiam integrae inveniuntur". To 

 judge from my material, however, the wings also differ considerably in the shape — which 

 will appear from the annexed figure — being broader thon in the typical species, and al- 

 ways emar^nate at the apex. There are also other differences, which will appear from the 

 following description: The stems are several, ascending at the base, frequently ligneous, 

 low, only 20—25 cm, high, as a rare exception to 30 cm. high, which is only about half
