on shorter pedicels, and that its leaves are more "clearly differ- 

 entiated into blade and petiole/' the expanded portion of the 

 leaves being obovate. The congested character of an inflores- 

 cence is found to be by no means always accompanied by rela- 

 tively broad leaves, for some Ontario specimens examined by 

 me have an inflorescence answering to Professor Green's descrip- 

 tion, but the expanded portion of the leaf is oblanceolate. The 

 stolons are said to be equally leafy throughout, but that is quite 

 often the case in typical A, ?teodioica, Mr. Fernald assigns to 

 his A. 7ieodioica atteimata no other distinctive characteristic than 

 that exhibited by its involucral bracts. It does not seem well to 

 make sub-species on single characters, especially of a species 

 with such freely intergrading forms. The character of attenuate 



F 



bracts is accompanied either by relatively narrow or rather broad 

 leaves, and either by a close or tolerably open inflorescence. 

 Mr. Fernald has characterized another sub-species, viz., A,neodi- 

 oka grandisy of which I have seen no specimens. A, mpicola is 

 merely a dwarfish form of A. neodioica, with lemon - tinged 

 involucral bracts and basal leaves slightly narrower than is ordi- 

 narily the case in this species.

 Fernald, Rhodora, /. c, A. petaloidea ??wdesta Elias Nelson, 

 Proc. U. S. Nat. Mus. 23:710. 1901. — In this species we have a 

 connecting link between the unusually well marked A. negleeta 

 and A, ambigens. Though grading into A, neglecta it may be 

 distinguished readily from that by its corj-mbosely cymose inflo- 

 rescence and generally broader leaves. The heads are as a rule 

 more numerous than in A. neglecta. In that species, as noted by 

 Mr, Fernald, the staminate plant is quite as common as the pis- 

 tillate, while in this it is very rare. As in A, neglecta, the thin 

 tomentum of the upper surface of the leaves is either persistent 

 or deciduous. In outline the leaves vary from spatulate or 

 oblanceolate to obovate-cuneate, and in width from 7 to 17'"°'.
