SOME ANTENNARIAS OF NORTHEASTERN AMERICA. 
M. L. FERNALD. 
Duriné the fifteen years since our northeastern species of Anten- 
naria received detailed study a vast amount of material has accumu- 
lated. For the most part this has fallen readily into the categories 
already defined; but a few plants, especially from eastern Quebec, 
Newfoundland and Labrador, are so different as to demand special 
attention. Two of these, A. eucosma Fernald & Wiegand and A. 
alpina, var. cana Fernald & Wiegand, have recently been defined; ! 
but the following have not heretofore been worked out. 
ANTENNARIA pygmaea, n. sp., nana 3—4.5 cm. alta monocephala 
humifusa, stolonibus assurgentibus perbrevibus haud elongatis; foliis 
basileribus oblanceolatis mucronatis S-14 mm. longis 2.5-3.5 mm. latis 
supra glabris vel glabratis subtus laxe lanatis vel glabratis, caulinis 
circa 9 confertis lineari-oblanceolatis 6-14 mm. longis subtus lanatis 
supra glabris vel glabratis, apice plano scarioso glabro 1.5-2 mm. 
longo lanceolato vel anguste deltoideo; involucro femineo hemi- 
sphaerico 7 mm. alto 12-13 mm. lato (in specimine siccato) basi lanato; 
bracteis 5-seriatis valde imbricatis oblongis obtusis, exterioribus fuscis 
cum apice breve stramineo, interioribus cum apice elongato scarioso 
stramineo munitis.
