ISG GOLDFISH VARIETIES AND 



HERPESTIS 



Her pest is ample.vicaulis bears a general resemblance to Moneywort, 

 but in essential characteristics is quite different. It is a pure aquatic with 

 thick leaves and a stout stem. Native to the ponds of Southeastern 

 United States as far as Florida. It is one of the best of recent additions 

 to aquarium plants. On account of being a slow grower its introduction 

 is not likely to be rapid, but once established it does very well, holding its 

 bright green leaves a long time. When out of the water it has a pleasant 

 faint odor. Being of Southern origin it will prosper in the temperature of 

 tropical aquaria where some plants will not do so well, although it thrives 

 in cool water also. Incorrectly known as Bacopa. 



CALLITRICHE 



Floating in small, cool streams throughout the United States and 

 Lower Canada one will find patches of brilliant, light-green small leaves. 

 Examination will show them to be the floating leaves of a long-stemmed 

 plant growing in the mud. These are various forms of Callitriche, or 

 Spring Starwort, sometimes also called Water Fennel. When the plant is 

 loosened we find it disappointing, for the lower leaves are thinner and 

 quite different in appearance. The stems are tangled and difficult to 

 disengage. 



Callitriche z'erna is the commonest form, as well as the most easily 

 established in the aquarium, but it shows to best advantage in shallow 

 tanks where a top view can be had of the surface leaves. It should, how- 

 ever, only be kept with tropical fishes unless it is intentionally given to 

 goldfishes to eat, as they are fond of it. The stems and roots when taken 

 are usually swarming with various aquatic insects and Crustacea. 

 Although many of these are good fishfood it is best to thoroughly rinse 

 this and all other plants before placing in the aquarium. 



HIPPURIS 



Formerly used as an aquarium plant. Mare's Tail has been over- 

 looked of recent years, possibly on account of its tendency to stand above 

 the water. Used in a suitable way this feature could be utilized to 

 advantage. It transplants well and will thrive under varying conditions, 

 but does best in ample light. Occurs in swamps from Labrador to 

 Maine and also the Pacific Coast. 



MONEYWORT 



Lysmachia nummularia or Moneywort is also known as Wandering 

 Jew, Creeping Jenny and Herb-twopence, the latter name and Moneywort 

 no doubt being derived from the rounded shape of the leaves. It is com-
