Cellulfe sphsericfe vel oblongje, spinis (neque setis) longis, 

 rigidis 4 (polaribus 2, equatorialibus 2) armatae, basibus spinarum

 valde expansis, apicibus obtusis vel minute cuspidatis, in vicem 

 spinarum inveniuntur.

Syn., Lagerheimia Chodati Bernard, Protococc. et Desm., p. 170, 

 f.349, 350. In its younger stages, this plant resembles a Lager- 

 heimia, but, instead of hair-like or bristle-like setse, the cells 



are furnished with four rigid spines {^^ forte barbe roide a 



Vextremite tres Jim et Ires at^we" — Bernard); and these are not 

 subapical, but exactly polar and equatorial. More mature cells, 

 gathered from the lake in Parramatta Park, have convinced me, 

 however, that the platit is organised on quite different lines to 

 Lagerheimia. The stiff spines have become very slender pro- 

 cesses, with blunt or minutely cuspidate apices, and very
