74 Fresh Water Aquarium 



plant, from southern waters, is of rather 

 recent introduction as an aquarium plant, 

 and as far as we have observed it is most 

 promising. The broad oval leaves are 

 placed in pairs around a thick fleshy stem, 

 in such a way that each pair stands in right 

 angles to the previous one. The pairs are 

 close together and each leaf half surrounds 

 the stem. Five main ribs start from the 

 base, branching outward and toward the 

 point of the leaf. The color of the leaves 

 varies from a somber olive to a bright green. 

 The whole plant has a pleasant odor some- 

 what resembling that of a ripe lemon. The 

 flowers are inconspicuous. 



In Monniera a plant of a new form and 

 character is introduced in our aquariums. 

 The stems will grow rapidly and when reach- 

 ing the surface will lie flat on the water. 

 AVhile the short, dense, newly-planted 

 branches seem rather stiff, a few weeks of 

 good growth will transform them into a very 

 graceful, desirable addition to our aquatics.
