cells are somewhat lax, and the alar cells are ganerally rather 
abruptly enlarged, lax, thin-walled, and hyaline, forming clearly 
marked auricles, and strongly decurrent, so that the line of insertion, 
gr a leaf is ear efully detached is more or less semicireular, whereas 
n D. fluitans it is almost straight or only slightly curve T 
ic vary much in direction, being strongly faleate with the apex 
of the stem hooked, or almost straight, with the leaf acumen only 
wana oblique, and the tips of the stems quite straight. It is also 
usually a much weaker, more straggling plant than D. fluitans, with 
less markedly pinnate branching. 
A specimen from L. Wakatipu, leg. J. Meiklejohn, was na 
by Renauld (in a letter to Rev. D. Lillie) ‘‘var. nov. Senate

and strongly hoped stems. I have received an even more strongly 
-marked form of this ‘variety from Wairoa, Hawkes Bay, collected 
by E. A. Hodgson 
D. aduncus is - think a rare or perhaps overlooked species.
