nial, but difficult to hibernate. The leaves, 

 broad, heart-shaped, form a rather dense 

 rosette. If grown in a light place they will 

 show brown stripes on a green ground. It 

 propagates by runners ending in new plants. 

 In a high temperature the Trianea reaches 

 a much larger size than in the cold aqua- 

 rium, so that it seems like quite a different 

 plant. During the summer it will do well in 

 a sunny pond or basin. 



Arrow-wort (Sagittaria spf). This comes 

 with other aquatics from Florida. The 

 plant, as far as observed here, grows com- 

 pletely submerged. While the flower stem 

 appeared on several specimens we have never 

 had an opportunity to see it come to per- 

 fection. The plant in itself with its dra- 

 caena or yucca-like leaves is interesting and 

 ornamental enough to desen^e a conspicuous 

 place in the aquarium. It is of a bright 

 green color and succeeds well under ordi- 

 nary conditions.
