OF THE GENUS ARENARIA. 353 
the branches of the stem and the lengthening of the internodes, 
the fasciculate leaves become discrete, so that it may be seen that 
between two pairs of large fully-developed leaves several pairs 
of smaller leaves are intercalated. Where the branches remain 
short and undeveloped, so that the upper portion of the 
flowering stem does not branch out, the stems are few-flowered, 
and such specimens were referred by Grisebach to A. biflora. 
Boissier, however, very properly referred them to this species, 
reducing them to the variety next mentioned.

The species was founded on Kamtschatka specimens. Regel, 
who was able to examine specimens from other localities for the 
Purpose of figuring the plant, draws attention to the 1-nerved 
sepals, and says that the petals are ovate-subrotund, not obovate- 
cuneate as in the original description, which must have been 
Wn up from more shrivelled specimens.
