will be seen from the above account of its forms that as to invo- 

 lucral bracts, glandulosity, and presence of ciliate hairs it pre- 

 sents the same variations as A. ambigens. As to. stature, size of 

 leaves and involucres, and general habit it resembles that species 

 very closely and indeed it grades into it. Although there is no 

 sharp line of demarcation between these two species, yet it 

 seems w^ell to let the two names A, ambigcns and A. Parlinii 

 stand for the two categories of forms, those with permanently 

 tomentose upper surfaces of the leaves falling into the former, 

 and those with leaves smooth above or nearly so into the latter. 

 From A. plaiitaginifolia the species is quite readily separated, and 

 though thechief distinction is that of size thedifference isconstant, 

 and I think no one who once has formed a mental picture of the 

 two species would have any difficulty in distinguishing them. 



Antenxaria propinqua Greene, Pittonia 4 : 83. 1899. — Origi- 

 nally described from staminate specimens only, collected at 

 Harper's ferry, West Virginia, but now also known to me through 

 plants secured by G. B. Ashcraft at Berea, Ohio. This collection 

 contains both staminate and pistillate specimens. Even the pistil- 

 late plants are rather low, only 16^"" high; the heads few and 

 closely congested, and the involucres 8 '""' high. The herbaceous 

 portion of the involucral bracts is livid green and glandular. 

 The inner bracts of the pistillate involucres are narrow and acu- 

 minate, while the outer are somewhat broader, their tips oblong, 

 lanceolate, or oblong-linear, acute or obtusish. The pappiJS 

 bristles in the staminate flowers are only slightly narrower at 

 the tips than those observed in some specimens of A, Parlinii. 

 m more specimens of A, propinqtia are at hand, we shall be 

 able to judge better of its claims to specific rank. 



Antennaria Brainerdii Fernald, Rhodora i: 153. 1899. — I^ 

 is doubtful whether this can be maintained as a distinct species. 

 As exemplified by Mr. W. W. Eggleston's specimens of 1899 and 

 President Brainerd's of 1900, it is certainly very closely allied to 

 A. Parlinii on the one hand and to A, ambigens on the other. In 

 both of those species, as we have alreadj^ noted, the presence or 

 absence of ciliate hairs is a matter of much variation, and m
