Herschell Isl. In full bloom on July 13th, 1906. 
The specimens from Herschell Island differ from the typical form in 
having (very) small bulbils in the axes of all the cauline leaves, besides 
developed flowers in the upper ones, and they approach in this way 
S. cernua L. very much; in fact it is open to doubt if the species is to be 
maintained or if it would be better to reduce it to a variety of S. cernua L. 
KJELLMAN has collected typical S. cernua L. at Port Clarence; the 
specimens are now in the Riksmuseum, Stockholm.
