225 . Loiseleuria procumbens, Desv. [Lit. Arct. 34' 36, 37 a, 38 ; 
Alps 2, 9.] The flower is slightly protogynous with ultimate self-fertiliza- 
tion on the fall of the corolla and sometimes before. The flowers are very 
little visited ; Bombi pass them over in search of those of Vaccinium ; they 
fill with water in bad weather. Yet each one sets seed. Like several other 
alpines which grow at Clova they are extremely variable, frequently being 
6 - or 7 -merous.
