We have seen no ripe fruit of the West Indian plant but judge its 
size to be much less than in the European forms. The Antheridia are also 
small, about -3 mm. in diametro.

The West Indian plant is a rather small and slender form from 
7—10 cm. high. The branchlets consist of 4—5 segments, the posterior 
braet-cells are rudimentary or one of them is developed, the anterior are 
‘ shorter than the fruit. "The antheridium is large, -36 — -40 mm. in diameter, 
the oospore about -54 mm. long and -37 mm. broad.
