278 PITTONIA. 
much broader and somewhat ovate-lanceolate: bracts of the 
involucre (the female plant only) all elongated, the greenish 
or reddish herbaceous basal part passing gradually to the 
very thin oblong obtusish and linear acuminate scarious 
tips. 
Sterile knolls and banks, Drew’s Harbour, British Colum- 
bia, 14 May, 1876, Dawson; sheet n. 11292 of the Canadian 
Survey collection. Evidently a northwestern maritime ally 
of the eastern A. plantaginifolia; very peculiar in its broad- 
bracted and somewhat panicled inflorescence, the flowering 
stems suggestive of those of some smaller Petasites. 
4— + Upper face of foliage permanently more or less woolly. 
A. pECIPIENS. Of the large dimensions, short stolons, 
broad petiolate triple-nerved leaves, and the general habit 
of A. plantaginifolia, but leaves of thin texture, never glabrate 
above, but always, even in full maturity, pale with at least 
a thin and sparse lanate or floccose tomentum, the ground - 
color a dark green: scarious tips of the inyolucral bracts in 
the female plant narrow and acute. 
While ransacking the wild and waste places about Wash- 
ington last May, in quest of male plants of A. plantaginifolia, 
I-came at last to an extensive field of exclusively male 
plants which, though growing in different soil, and under 
less exposure, and also presenting what I took for a less 
promptly deciduous indument, I allowed to pass for the 
species above named. In my distribution of authentic 
specimens of what I had called A. plantaginifolia, I sent out, 
in each instance, female A. plantaginifolia and male 4 
decipiens ; and did this all the while half apprebending that 
I might be acting indisereetly. Later in the season, a$ the 
foliage of the female plants in every field about me grew 
larger and more plantain-like, even more fleshy and firm 10 
texture, retaining its bright green hue, that of my mà 
ones in the woodland station remained thin, retained all 155
