The apex of the specimen has been truncated to a width of about 
? mm., but a continuation of the side lines makes it probable that 
the termination was acute. The base is rounded, but the folding in 
of the sides at the position of the midrib, indicates the existence of 
a tapering base which probably extended into a short and margined 
petiole which may also have been sheathing. The nerves are very 
obscure and observable at one point only, thus making it doubtful if 
they were prominent in the original plant. The veins are fine and 
numerous though obscure. They are uniformly distant 1 mm., and 
they are connected by transverse veinlets at intervals which could

not be determined with accuracy. The undoubtedly endogenous char- 
acte: of this specimen has led to a comparison with the genus Clintonia 
which it closely resembles. A diagnosis of a leaf taken from C. bore- 
alis, gives the following results: — 
Leaves very variable, elliptical oblong to narrowly oblong; midrib 
obscure; veins numerous, not prominent, distant 1 mm., and connected 
by transverse veins which are somewhat conspicuous, rarely oblique, 
and distant about 2 — 3 mm.
