On the mountain lying east of Mardjanaj a similar con- 
dition to that on Mt. Hens was found. The vegetation on 
the north slope was rather dense, in some places close, and 
comprised Dracocephalum discolor, Nepeta kokanica, Oryzopzis 
purpurascens, Draba turcestanica, D. fladnizensis aff., Astragalus 
alatavicus, Isopyrum anemonoides, Potentilla sericea, Oxytropis 
immersa, Psychrogeton turcestanicum, Elymus sibiricus, Chrysan- 
themum Richteria, Gagea stipitata, Festuca ovina var. valesiaca, 
Poa attenuata, Artemisia macrocephala, Hedysarum cephalotes, 
and Sedum Rhodiola. Of these species only Psychrogeton and 
Hedysarum grew on the south side of the mountain too; 
they are moreover to be found in “the Pamirs” (the flats). 
This north-side vegetation does not cover the entire north 
side of the mountain, but apparently only those places where 
the exposure is somewhat eastern. — Only here are marmots 
found, which was likewise the case on the mountain described 
above. There were also places with a slight western exposure 
and which were covered with Eurotia-formation (Eurotia and 
Stipa orientalis). 
On the summit of the mountain, about 4,300 mètres 
above sea-level, in the pass between too peaks lying east and 
west of each other, the following characteristic plants were 
gathered. 
On the south side of the pass, widely separated, Hedy- 
sarum cephalotes and Oxytropis Poncinsii. 
On the north side, Sedum Rhodiola, Nepeta kokanica, 
Draba fladnizensis aff. Hedysarum cephalotes, grasses and 
single specimens of Solenanthus stylosus, forming a luxuriant 
if not close vegetation. 
Under the boulders lying on the summit of the mountain, 
large tufts of the interesting cruciferous Didymophysa Fedt- 
schenkoana, With fresh, succulent leaves, small white flowers, 
and puffy bladder-shaped fruits were growing. Smelowskia 
annua was likewise found here.

northern slopes, lists of plants from the eastern and southern
