The tln^ee species of Allium just enumerated above are so nearly related to 

 one another as to have led some botanists to form an opinion that they are of 

 one and the same species, Komarov, for instance, in his Flora Manshuriso treat- 

 ed A. strlctnm and A. splendens as synonyms of A. lineare. 



A comparative study of a large number of the specimens of these plants 

 collected in Hokkaido and Saghalin, however, leads us to consider them as three 

 quite distinct species. They differ from one another in some important morpholo- 

 gical characters as well as in their habitats". 



Allium lineare L. is known at present only from the northern portion of 

 Saghalin. It is readily distinguished by its long exserted stamens and also by 

 its long acuminate simple teeth, one on eacli side at the base of the filament. 

 The teeth are of about the same length as the perianth ; sometimes they are a 

 little longer. 



Allium stridum Schrad, is an alpine species. It has small rather compact 

 umbellate head composed of fewer and smaller floweis. The stamens are of about 

 the same length as the periantJi, often becoming a little exserted. The teeth are 

 generally simple and obtuse, and aie aboat one third as long as the perianth. 

 Rarely they are provided with very small secondary teeth. 



In Allium splendens Willd, we have the largest umbellate heads composed of 

 numerous larger flowers. The stamens are long exserted ; their teeth are of 

 medium size, each of which is conspicuously lacerated at the apex. It has the 

 widest distribution in Hokkaido and Saghalin, and grows commonly in open 

 grassy plains.
