150 Rhodora [AuGusT 
Elakatothrix Americana, n.sp. Forming gelatinous, laciniate 
and anastomosing masses, several cm. long, attached to other plants. 
Cells more oval than in Æ. gelatinosa Wille ; the cell divides across the 
middle, but the daughter cells grow obliquely past each other, causing 
irregularity in the structure of the thallus. Length of cells 12-25 pm; 
breadth 6-11 u. — Found at Monroe, Conn., May 30, 1895 ; collected 
by Miss Grace Angeline Smith.

FURTHER NOTES ON NEW ENGLAND ANTENNARIAS. 
M. L. FERNALD. 
Tue Antennarias, it may well seem, have received during the past 
two years more than their share of attention in the literature of Ameri- 
can systematic botany; yet so active have been three New England 
botanists during the past May and June that much more has been 
added to our knowledge of that group. In Vermont President Ezra 
Brainerd, of Middlebury College, has made an exceedingly thorough 
study of the plants in the field; while Mr. W. W. Eggleston of Rut- 
land, Vermont, and Mr. J. C. Parlin of North Berwick, Maine, have 
both made critical notes and collections. These careful observations 
have extended the known ranges of many formerly recognized New 
England species, and in Maine and Vermont a novel plant with marked 
and apparently constant characters has been collected. The following 
notes based primarily upon the collections above referred to may be 
considered supplementary to the two papers already published upon 
the genus Antennaria in New England." 
Antennaria ambigens (4. arnoglossa, Greene, var. ambigens, 
Greene, Pittonia, iii. 320 ; A. Parlinit, Fernald, var. ambigens, Fernald, 
Proc. Bost. Soc. Nat. Hist. xxviii. 244). This plant formerly given 
only varietal recognition is now elevated without hesitation to specific 
rank. Though it bears some purple glands like those of 4. Partiniz, in 
all its other characters — the dull pubescent upper surfaces of the basal 
leaves, the arachnoid glandless upper faces of the cauline ones, and the 
subcapitate inflorescence — it differs strikingly from that species. In
