THE FLOWERS OF KOLGUEV 401 
CRUCIFER/ 
Cardamine pratensis L. Cuckoo Flower. 
This plant is distributed all over Kolguev where conditions are suit- 
able, e.g. along the edges of streams. But it is smaller than our cuckoo 
flower, and I never saw it lilac, but always white. 
Arabis alpina L. Alpine Rock-cress. 
On Kolguev this is very local. I found it only on the barest north- 
facing clay banks in August and September. Such places had been 
covered with snow till late, and with the melting snow the clay had 
liquefied and slid down. Here A. afina grew. Connected possibly 
with the extreme shortness of time thus left for fructification is the fact 
that the seed-pods were far developed (sometimes to a length of 1} 
inches), in all cases before the petals showed any signs of falling. 
Draba rupestris R. Br. 
Common on all the sand-hills. 
D. alpina L. 
This pretty little draba was quite common on the Pesanka plateau ; 
elsewhere it was little represented, though I picked some plants on the 
Pugrinoy. 
Cochlearia danica L. Danish Scurvy-grass. 
Abundant everywhere. 
VIOLACE 
Viola biflora L. Twin-flowered Violet. 
I did not find this flower in Kolguev till August 2nd. It was 
common on all high dry banks covered with light fine grasses, 
eg. Poa arctica.
