16 Rhodora [JANUARY 
Bernh.), the old fashioned Feverfew; T. atratum (C. atratum L.), an al- 
pine Marguerite closely related to our introduced Daisy or White Weed, 
C. Leucanthemum L. or Leucanthemum vulgare Lam.; and T. indicum 
(C. indicum L.), one of the progenitors of the garden Chrysanthemum. 
Somewhat similarly, Boissier,! in 1875, maintained Chrysanthemum 
in its restricted sense and threw the others, including Tanacetum, 
into Pyrethrum. The problem, as already said, is essentially one for 
the European student to settle, since the great bulk of species is 
Eurasian, but until there is fuller agreement among the more thorough 
students of Eurasian Compositae it seems better for us to maintain, 
for the present, Tanacetum as generically distinct from Chrysanthemum 
in the restricted sense. If Tanacetum, Pyrethrum, Leucanthemum, 
etc., constitute a single genus distinct from Chrysanthemum, an 
interpretation which has much authoritative support, the earliest 
generic name is, of course, Tanacetum L. Sp. (1753) which antedates 
Leucanthemum Mill. (1754) and Pyrethrum Scop. (1772).

Iste au Haur PrawTs.—During the summer of 1921, I found 
growing amongst various grasses on what is known as Birch Point, 
though there seem to be no birches there, Luzula campestris (L.) 
DC., var. acadiensis Fernald. This will be found described by Prof. 
Fernald in Ruopora, Vol. 19, p. 38, from eastern Canada. His 
comment on my plant is “first in Maine." 
About the same time I found on York Island, which lies close to 
the eastern shore of Isle au Haut, a golden-rod, Solidago lepida DC., 
var. molina Fernald, which is also “new to New England." This 
was described by Prof. Fernald in Rnopona, Vol. 17, p. 9. It is 
mentioned in Gray's Manual (7th edition) under S. canadensis L., 
var. gilvocanescens Rydb., but with no footing in New England. 
I wish to acknowledge Prof. Fernald's kindness in identifying both 
of these plants for me.—NATHANIEL T. Kippken, Milton, Massach-
