412 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. 



rosea D. C. Eaton, King's Exped. 5 : 185 (name only) ; A. rosea 

 Greene, Pittonia, 3: 281. 



Professor Greene claims that Nuttall's A. parvifolia is the same as 

 ray A. microfhyUa. I have seen Nuttall's type in the Philadelphia 

 Academy, and it is the same as A. dioica rosea Eaton. Professor 

 Greene's reduction of my A. microphylla was unwarranted and his 

 arguments are without foundation. Nuttall's description of the stami- 

 nate plant is also correct and does not apply to m}^ A. microphylla. 

 While the bracts of the pistillate plant are generally strongh^ tinged 

 with red, this is not the case in the very rare staminate plant. In the 

 Columbia collections there is not a single specimen of the latter and 

 the other larger herbaria may be just as deficient. Good specimens 

 are represented by our number 5/59,' these have yellowish-white 

 bracts. 



Grows in meadows and open woods, at an altitude of 2000-2500 m.

* Antennaria imbricata E. Nelson, Bot. Gaz. 27: 211. 



Very closely related to the preceding, and perhaps a form of it, 

 but differs in the broader spatulate leaves and slightly larger heads, 

 with more imbricated bracts.

* Antennaria microphylla Rydb. Bull. Torr. Bot. Club, 24: 303. 



Characterized by the very small spatuhite white leaves, and the 

 small heads with slightly greenish-tinged bracts. It grows on dry 

 hillsides, at an altitude of 1500-2500 m.
