244 Rhodora [NovEMBER 
SENECIO BALSAMITAE, Muhl., var. firmifolius, Greenman, n. var. 
Stems o.8 to 2 dm. high, more or less tufted: lower leaves mostly 
short-petioled, elliptic-oblong to subrotund, 0.5 to 4 cm. long, 5 to 20 
mm. broad, crenate-dentate to sublyrately pinnatifid, thick and firm 
in texture, at first, as well as the stem, white tomentulose, but soon 
glabrate; upper stem-leaves much reduced and often prolonged 
into a linear entire attenuation: involucre and technical characters 
of the head like the species. —In red limestone detritus, crest of Les 
Murailles, Percé, Gaspé County, Quebec, 17 August 1904, J. F. Col- 
lins, M. L. Fernald & A. S. Pease (type, hb. Gray); also in lime- 
stone detritus, Mont Rouge, Percé, 23 July 1905, J. F. Collins & 
M. L. Fernald (hb. Gray). Specimens secured by Messrs. Collins 
and Fernald at Cap Barré, Percé, 23 July 1905, are distinctly inter- 
mediate between the variety and typical examples of the species. 
The variety is distinguished chiefly by the short relatively broad 
leaves and their thick firm texture. — J. M. GREENMAN, Field Colum- 
bian Museum, Chicago. 
A PALE FORM OF AVENA STRIATA.— Avena striata Michx. has 
the empty glumes and often the flowering glumes strongly tinged 
with purple — so much so as to have received from Torrey the name 
Trisetum purpurascens. On some of the mountains of Maine and 
eastern Quebec, however, the prevailing form of the plant quite lacks 
this purple coloring which is so characteristic of the species, and 
has instead whitish or pale straw-colored empty glumes and pale 
flowering glumes. The plant seems to have no other distinguishing 
character, but in the regions where it occurs it is so constant and 
characteristic as to merit the distinctive name : —
