(Greene) Robinson, n. comb. {Kyrstenia hetulaefoUa Greene, Leafl. i. 

 10, 1903.) It differs, however, in having decidedly narrower leaves, 

 which are entire at the attenuate apex ; the bracts are also of different 

 form, being narrowly lanceolate, quite entire, and strongly attenuate ; 

 furthermore the involucral scales are of a more herbaceous texture. 

 Whether these distinctions will prove constant cannot be foretold ; but 

 on the whole they appear rather too significant to permit the placing 

 of the present plant under E. hetulaefoUam as a variety.
