IMPATIENS BIFLORA, FORMA PEASEI.— When this name was pub- 
lished,! I had never seen living material of the plant in question. The 
description (for which, as it appeared, I was responsible) was drawn up 
from the reports of three trustworthy botanists who had collected the 
plant and from statements on herbarium labels. All agreed in 
describing the flowers as “ pink” or "roseate." Moreover, the flowers 
in certain herbarium specimens examined showed traces of pink color- 
ation. 
Since that time, I have had an opportunity to examine living plants 
of f. Peasei at the type station and at two other localities in the White 
Mountain region — with somewhat disconcerting results. Points 
of view, it appears, make a difference. "The flower of the real f. Peasei 
is not pink throughout as described and as I had supposed. Seen from 
in front (that is, as one looks directly into the throat of the perianth) 
it does, indeed, give the impression of a pink blossom; and this fact 
doubtless explains the statements of collectors in regard to it. But 
the pink coloration is confined to the inner surface of the spreading 
perianth-parts, where, in all forms, the spots are usually most numer- 
ous. The back of these same parts and the saccate sepal— really,
