A very curious little plant. Mr. Kirk describes the anthers as solitary; but in 
Mr. Petrie’s Lake Waihola specimens, which are the only males that I have seen, I make 
the anthers to be 2, placed back to back, but closely resembling a single 4-celled 
anther. At the same time it is not easy to satisfy oneself as to the structure of 
the anther from an examination of dried specimens.

Marine submerged plants. Rhizomes slender, branched, creeping and 
rooting at the nodes, often matted. Stems short, slender, leafy, com- 
pressed. Leaves distichous, alternate, narrow-linear, orass-like, 1-5-nerved, 
sheathing at the base ; sheaths stipuliform, with inflexed margins. Flowers 
monoecious, the males and females placed alternately upon one face of 
a narrow spadix enclosed. within the dilated membranous base of a leaf. 
Perianth wanting. Male flowers: Anther solitary, sessile, oblong, cylindric, 
curved, 1-celled; dehiscence longitudinal; pollen confervoid. Female 
flowers: Carpel solitary, laterally attached above the middle, narrowed 
into a short subulate style; stigmas 2, capillary; ovule pendulous from 
the apex of the cell. Ripe carpel oblong, membranous, bursting irregularly. 
Seed pendulous ; testa membranous, often striated ; embryo large, deeply 
grooved, the linear incurved cotyledonary end sunk in the groove. 
Three or four closely allied species are known, found in shallow water on the 
shores of most temperate regions.
