dance of seedlings, but which species they represented could not 

 be determined. They were found, ho^vever, near patches in which 

 A. Parlinii {A. arnoglossa)^ A, plaiitaginifolia^ and y^. neglecta w^ere 

 growing. In Antennaria, as well as in the related genera Gna- 

 phalium and Anaphalis, the plants may be polygamo-dioecious. 

 A, plajitagini folia (^A. decipiens Greene), however, is the only 

 species in which I have observed perfect flowers. 



In consequence of my distribution of North American Anten- 

 narias I have received many collections from various parts of 

 the United States and Canada, thus giving me an opportunity 

 to study among others the species of the eastern United States. 

 The material in the U. S. National Herbarium has been at my 

 disposal, and through the courtesy of Professor E. L. Greene it 

 has been my privilege to examine the types of his species. I 

 am under great obligations to Mr. M. L. Fernald for communi- 

 cations of specimens and other favors. The facts which have 

 been brought out in the course of my study of the eastern spe- 

 cies and the opinions I have been constrained to entertain are set 

 forth in the following notes, which I hope will not be without 

 interest to the students of this genus. 



Antennaria labradorica Nutt. Trans. Am. Phil. Soc. 7:406. 

 1 84 1. — A very good species, originally described from Labra- 

 dor specimens. It is in part the A, alpitia of Britton's ManuaL 

 There can be no doubt as to its distinctness from A. alpina, 

 Nuttall himself says of it : **at first glance resembling A, alpina, 

 but more nearly allied to A. plantagineay Its affinities are with 

 A. canadensis and A, neodioica^ the brownish involucres suggest- 

 ing A. alpina. I have examined an undoubted specimen of this 

 species deposited in the herbarium of the Geological Survey of 

 Canada (sheet no, 14363). Since Professor Greene, who has 

 seen the same material, gives a brief characterization of the 

 species,^ I will here only record some measurements taken of 

 some parts of the plants on this sheet. Basal leaves 1-2*'°' long; 

 lowest pedicel of the inflorescence 3.5*^°^ ^^ng ; involucres ^-^ 

 high.
