1914] Fernald, — Antennarias of northeastern America 133 
yellowish mostly oblong involucral bracts. The plant has heretofore 
been recorded only from the slaty ledges along the Mattawamkeag 
River in Aroostook County, Maine; but in 1911 it was found in pro- 
fusion, by Messrs. Wiegand, Bartram, Darlington and the writer, upon 
the slate and sandstone ledges below the Grand Falls of the Exploits 
River in Newfoundland and in some abundance on rocks and head- 
lands at other points in eastern Newfoundland. Along the Exploits 
River both A. neodioica and A. rupicola are in the greatest abundance 
and it was there evident that, though very distinct in their extremes, 
they present numerous transitional tendencies. ‘Since all the Anten- 
narias yet found in Newfoundland are strictly pistillate, with the single 
exception of the unique A. eucosma, the transitions can scarcely be 
explained as of hybrid origin and it seems wisest to treat 4. rupicola 
as an extreme variety of A. neodioica. Another interesting extension 
of its range is furnished by a collection of var. rupicola from the rocky 
shore of the Onaman River in the Thunder Bay District of Ontario, 
where it was secured by Mr. H. E. Pulling in the summer of 1912. 
The known area of var. rupicola now extends from eastern Newfound- 
land to northern Maine and northern Ontario. 
A. PETALOIDEA Fernald, var subcorymbosa (Fernald), n. comb. 
A. neglecta, var. subcorymbosa Fernald, Proc. Bost. Soc. Nat. Hist. 
xxviii. 246 (1898). 
When first put forward as a variety of A. neglecta, this plant was 
known only from a single station on Mt. Desert Island, Maine; and it 
was distinguished from 4. neglecta by its very tall flowering stems and 
by "heads loosely subcorymbose on elongated pedicels, the lowest 
sometimes 6 em. long: involucral bracts nearly all acute, the inner long- 
attenuate." Subsequently, when the northern representative of A. 
neglecta with corymbose heads, A. petaloidea Fernald,! was described, 
A. neglecta, var. subcorymbosa was included in it. But during the 
succeeding fifteen years, while a large amount (about 75 numbers) 
of A. petaloidea and its var. scariosa Fernald ? has accumulated, the 
original sheet of A. neglecta, var. subcorymbosa has not been matched 
in certain characters, which were not at first noticed as peculiar. In 
true A. petaloidea, with the involucral bracts with petaloid white tips, 
the basal leaves are spatulate and decidedly rounded at summit, and 
the cauline leaves extend remotely but regularly to the inflorescence. 
In var. scariosa, with the long-attenuate involucral bracts very scarious
