In view of the peculiarity of the bracts of Betula nana, var. Mi- 
chauzii, it was interesting to find in the ravine of one of the headwaters 
of the Ruisseau à la Neige on Mt. Albert, Gaspé County, Quebec, 
a colony of small trees and shrubs of Betula alba L. (B. pubescens Ehrh.) 
which showed a similar variation. In the Mt. Albert trees the bracts 
are mostly oblong and unlobed but an occasional bract is 3-lobed as 
in the typical form of the species. This tree of Mt. Albert may be 
designated 
BETULA ALBA L., var. elobata, n. var., trunco humili vel mediocri 
usque 6 m. alto; foliis maturis 4.5-6 cm. longis rhomboideo-ovatis 
basi rotundatis vel subeuneatis supra glabris subtus ad nervos pilosis; 
strobilis pendulis 1.5-2 em. longis 7-9 mm. crassis, pedunculis 0.7-1.3 
cm. longis; squamis oblongis integris vel undulatis ciliatis. Small 
or medium-sized tree (up to 6 m. high): mature leaves 4.5-6 cm. long, 
rhombic-ovate, rounded or subcuneate at base, glabrous above, 
pilose on the nerves beneath: strobiles pendulous, 1.5-2 cm. long, 
7-9 mm. thick, on peduncles 0.7-1.3 em. long: bracts oblong, entire 
or undulate, ciliate.— QUEBEC: crevices and talus of serpentine along

While these extensions are worth recording, I take no credit for the 
discoveries; for the past few years, whenever I have been on Cape
