* Eritrichium aretioides elongatum. 



Flowering stems 3-4 cm. long, covered with oblong erect leaves, 

 8-10 mm. long. 



This may be a distinct species, but the material is rather meager. 

 The typical E. aretioides is generally stemless, but if the flower- 

 ing branches rise 2-3 cm. above the basal clusters of leaves, the stem- 

 leaves are very short and mostly divergent ; the variet}^ therefore, dif- 

 fers much in general habit, although other technical characters, so far 

 as I can find, are lacking. 



Rare on dry hills, at an altitude of 2000 m.
