72 Rhodora [APRIL 
Antennaria canadensis, which is rare south of Boston, is, with the 
possible exception of 4. neodioica, the commonest species of northern 
New England, passing occasionally into the larger-headed and more 
attractive var. Randi. 
The northern Antennarias of greatest interest, however, are certain 
forms characteristic of the regions where they grow, but either misin- 
terpreted or quite unknown until the past summer. A large suite of 
specimens secured at various points along the line of the Bangor and 
Aroostook railroad show conclusively that the Mount Desert plant, 
formerly treated by me as a variety of A. neglecta, the Maine specimens 
then called A. campestris, and the northern New England forms called 
by me 4. neodioica, var. petaloidea, are in reality extreme forms of the 
same species. This plant was seen in great abundance in June 
throughout Aroostook County and at more southern stations in Piscat- 
aquis and Penobscot counties, where it is far more abundant, in fields 
and on grassy slopes, than the related 4. zeg/ec/a. Specimens have 
been referred to Dr. Rydberg who pronounces them very different from 
his western 4. campestris. When the Maine plant was provisionally 
referred to that species it was known only from autumnal leaf-speci- 
mens; but now, with abundant flowering material at hand, there is no 
need of further confusion between them. A. campestris, confined for 
the most part to the prairies west of the Mississippi, is a very low plant, 
rarely becoming 1 dm. high; on the other hand, the northeastern plant 
is often more than 4 dm. high. Low early forms of what is apparently 
immature A. neglecta closely simulate the western 4. campestris, but 
such plants have been carefully observed by Mr. J. C. Parlin, who finds 
that they later develop the characteristic racemose inflorescence of the 
eastern 4. neglecta. 
From Antennaria neglecta, with which the plant was formerly 
placed, field-observations show this northern plant to be very distinct. 
In June, when this species was in flower, its corymbose heads gave to 
the fields a /azuny or brownish-white color; while, in neighboring col- 
onies, the old and often over-ripe racemes of A. neglecta formed patches 
of purplish-white Or sometimes almost crimson. This color-character 
alone may not prove of absolute constancy ; but the corymbose inflo- 
rescence and much later flowering season, as well as its greater abun- 
dance in northern New England where the early 4. neglecta is a 
comparatively rare plant, distinguish it very clearly from that species. 
From A. neodioica, with which poorly developed specimens of this
