Pilularia nove zealandie, n. s. 
Root-stock creeping. Leaves solitary, 1-2 inches long, erect, setaceous.. 
Sporocarpium globose, 2-valved, 2-celled ; carpopodium } inch long, erect; 
raphe elongated ; micro-sporangia numerous, pyriform, each containing 
20-80 microspores ; macro-sporangia 20-25, ovoid ; macrospores globose, or 
. globose-ovoid, regular, not constricted. ; 
Hab.: South Island: Lake Lyndon and Lake Pearson, Canterbury.

In general appearance our plant resembles P. globulifera, L., differing 
externally in the 2-valved sporocarp, the longer carpopodium, and essentially 
in the non-constricted macrospores. It appears to be closely allied to P. 
nove hollandie, A. Br., from which it differs in the 2-valved sporocarp, 
erect carpopodium, and lesser number of macrospores. 
A species of Pilularia was detected at Whangape Lake, Waikato, by 
Professor Hutton and myself, in 1869, but the specimens were too imperfect 
to admit of identification.
