E"OTES ON THE GENUS UTRICULARIA. 

 By C. a. Topp, M.A. 



The genus Utricularia is not a large 'l omo ii ifej g o ugh widely spread, 

 ha\ang represen-tatives in all quarters ■ af-flre-g lobe, but it possesses 

 special interest as being one in which all the species appears' t'U' T)^" 

 carnivorous, and the object of my paper is to direct the attention of 

 tKe members of ou ^ elub to t he- stTtdy^9HJTe''Victorian representatives 

 of that genus as tliey possess points-of- intere st alilfe'TO'ThrttTflngist, 

 the botanist and the microscopist, and none of them have, I believe, 

 been yet described or drawn in detail.
