but they do best in wooden tanks. At best they are slow growers,

CRYPTOCORNE 



This attractive aquarium plant is an importation from Europe. 

 Although introduced several years ago, it has never received the atten-

 a good light if not disturbed. Propagation principally by runners. The 

 crown is at the surface of the sand.
