places in Wakhan, and built formerly by the Siaposhes, a 
tribe from Kafiristan. 
But for this matter as well as for the geography of 
Wakhan, reference may be made to OLUFSEN, who in “The 
unknown Pamirs” has given a detailed description of the 
country. A map is published by him in “Geografisk Tids- 
skrift” vol. 14. 
On the mountain-sides in Wakhan the vegetation was 
just as poor and dry as we had found it in High Pamir. 
However, in Wakhan we could study only the vegetation of 
southern slopes, because the expedition only followed the 
right bank, or north side, of the Pändsh River. 
On these slopes, exposed to the south, Anabasis wak- 
hanica, a low leafless suffrutex, usually having many dead. 
twigs among the green, was the most common plant. Pega- 
num Harmala, a hemicryptophytic Zygophyllacea, with deeply 
cleft leaves and thick narrow lobes, was likewise common, as 
were Andropogon Ishaemum, forming small tunicate tufts and 
having short gray hairy leaves, Eurotia ceratoides, Artemisia 
fragans, Centaurea repens, the annuals Kochia stellaris, Bassia 
hyssopifolia, both with narrow hairy leaves, and Salsola col- 
lina which has hard, very woody stems, and small, almost 
squamate leaves. 
In a few places, on dry mountain slopes, I found Astrag- 
alus lasiosemius, on September 11, with its leaves quite withered 
and the rhachides, alone, sticking out like thorns; and near 
Dershai I found a very few specimens of Acatholimon alata- 
vicum. 
This vegetation can best be compared to the Eurotia- 
formation of Pamir. Like that, it is a chamaephyte formation, 
in that 5 out of 11 species (46 °/o) are chamaephytes. It 
differs from the Eurotia-formation in containing 3 therophytes, 
(27 °/o), all Chenopodiaceae belonging to the long-lived type, 
(summer-annuals, PAULSEN), with xerophytic anatomy. I will 
not carry my comparison between the rocky vegetation of 
Wakhan and the Eurotia-formation further, as my acquain- 
tance with the former is too slight, based only on observa- ' 
tions made during one autumn and winter. 
As in Pamir, green stripes follow the river-courses, and
