. Morphological and Physiological Differences between 
Marsilia left on dry land and, that growing in water.—By NIBARAN 
CHANDRA BHATTACHARJER. Communicated by Dr P. C, Ray. 
In the rainy season the tank was full of water ; but with the 
advent of winter the water gradually sank to a very low level, 
leaving a number of plants, stranded on different kinds of 
soil. In some parts it became perfectly dry ; there the Marsilia 
plants were on their way to death: other plants were in moist 
soil, others in soft muddy soil, 
this circumstance afforded excellent facilities for observing the 
effect of desiccation. 
‘The Marsilia plants, which remained in water, possessed all 
the characteristics of a typical aquatic plant, the stem being 
spongy, light and green, and the leaves tolerably large with 
entire margins. 
1e plants which had come to be on dry land were much re- 
duced in size. The stem was solid, stiff, and covered with black 
cuticle. The leaves were much smaller, darker,-and had their 
margins crenated. 
_ But the most interesting point I noted in this case, and 
which was further corroborated by several other ‘observations:
