repeating the structure of the main axis. Flowers usually terminal 
on short shoots bearing a few leaves, the upper usually more or less 
connate, and two or more of the lower with ramuli in them axils, erect, 
emerging through the water, anemophilous. Pedicel 3-5 mm. lengthen- 
ing to 5-15 mm. in fruit. Perianth sepaloid, marcescent. Stamens 3, 
much exserted, on flexible filaments. Anthers ovate-oblong, bilobed. 
Ovary superior, at first much shorter than perianth, but after 
fertilization elongating to the same length as the perianth, slightly 
trigonous. Stigmas 3, long, hairy, the tips usually deciduous. Capsule 
9-ribbed. 
In streams of the Western Ghats 300-4,000 feet, often in 
gently moving water, rather common. First discovered by 
the Rev. E. Johnson. S. Kanara, at Beltangadi, 0. A. Barber, 
S. Ind. Flora, No. 2,517, 2,518 ! Malabar, in streams near 
Cochin, Rev. E. Johnson ! Anamalai Mountains, in the 
Sholai Aar, Monica Estate, at 4,000 feet, J. C. Willis ! Travan- 
core, at Mundakayam, 300 feet, T. F. Bourdillon ! 
All these forms show slight differences in size and shape 
of leaves, number of leaves on the ramulus, and other 
features, but much further study of material from many 
localities is needed before the varietal rank of the different 
forms can be decided.
