1902] NOTES ON CERTAIN SPECIES OF ANTENNARIA 123 



I 



and serrulate are at times somewhat dilated toward their apices. 



I am unable to separate A. iiemoralis Greene from this species. 

 It is of the same size and has the same foliage characteristics as 

 A. plantagini folia. Mr. Albert Ruth has sent me some material 

 secured by him in the same grove in which was collected the 

 type oi A.nonoralis. The leav^es in these plants vary from ovate 

 and elliptic to round ovate, and the arachnoid pubescence is 

 persistent on the upper surface. There were two pistillate plants 

 in Mr. Ruth's collection, and these have the narrow involucral 

 bracts characteristic of A. plantagini folia. 



Hermaphrodite flowers apparently are not infrequent in this 



species. Plants with some flowers containing well developed 



stamens and pistils and plump akenes have been detected in 



three different collections. These specimens are respectively 



■ ^rom Biltmore, North Carolina, Takoma park, D. C. [E. N. 



Wilcox, 1 901), and Knoxville, Tennessee [Albert Ruth, 1901). 

 They are in each case accompanied by sterile plants. They are 

 readily distinguished from both the strictly pistillate and the 

 staminate individuals by their involucral bracts, which are much 

 broader than in the former, but not as broad as in the latter; or, 

 to be more definite, their obtuse, white tips are from oblong- 

 linear to oblong. The pappus-bristles are coarser than those of 

 the pistillate flowers, slightly thicker toward their apices and 

 somewhat serrulate. In their general appearance the heads of 

 e individuals having some perfect flowers resemble those 

 which are strictly pistillate, and indeed I at first mistook them 

 for pistillate plants. 



Antexnaria occidentalis Greene, Pittonia 3:322. 1898. 

 The plant w^hich I at present tentatively refer to A. occidentalis is 

 »' ^^^ ^- Fartvcllii of Mr. Fernald and Dr. Britton. It appears to 



be quite distinct, and is known to me through specimens from 

 New York, Vermont, Ontario, Michigan, and Wisconsin. As to 



th 



th 



e mvolucres and the outline of the basal leaves, it agrees so 

 well with Professor Greene's description of A. occidcfitalis that I 

 refram from assigning it a new name until satisfied that it is not 



that 



species.
