posed, short, needle-like leaves, decurrent at the base; 
twigs depart at an angle 60-70", straight, tapering slight- 
ly. The leaves are fewer and more distantly placed on 
the Greene Specimen. 
The third specimen discussed in this note is from 
Miminigash, Prince Edward Island. It was presented to 
Harvard University in 1875 by Francis Bain. Bain had 
identified the specimen as Araucarites gracilis Dawson. 
The specimen in our possession is from the type locality 
of Dawson’s plant, which David White renamed Wadl- 
chia dawsont sp. nov.

Diagnosis: (White loc. cit. p. 99.) 
‘*Branches apparently flat, distichous, with close and 
slender ultimate twigs, hardly tapering until near the 
blunt apex; leaves close, decurrent, linear-lanceolate, 
dorsally carinate, curving outward, and in the upper part 
curving upward and inward uncinnately or more or less 
distinctly faleately at the rather narrowly acute apex, 3 
to 6 mm. long, and broadest at the base, which is slight- 
ly carinate dorsad.”’ 
The specimen before me agrees with the figures pub- 
lished by Dawson from Nova Scotia and Prince Edward 
Island. White regarded the Nova Scotian plant as a dis- 
tinct species. On this slab are branches of the diminutive 
size suggested by Dawson’s figures and larger branches 
as large as those of the ‘‘typical’’ Walchia piniformis. 
White called attention to the close relationship between
