 with intermixed bidruslies, uear the outlet. 



Caslalia odorata, or wliite water lily, has a somewhat more general dis- 

 tribution, as scattered plants occur nearly all round the shore. There is a 

 number of stout plants growing in the bayou in front of the laboratories, 

 then there is none whatever until about ~()0 feet south of Chicago Hill 

 pier. From this place occurs occasional patches of the small form until 

 the large stretch of Nymphaea at the mouth of Clear Creek, is reached. 

 Here there is a wide, dense growth of the ordinary floating-leaved form. 

 There is a second large patch, similar to this one. in the bend at the south-

west corner of the lake. It is here nearly free from spatterdock. The broad 

 bay leading to the outlet has two belts, the outer belt of the stout form 

 growing almost out of the water in the rich muck at the edge of the shore, 

 and the ordinary form out in the water. (These are shown in Fig. 7.) 

 There are scattered small patches all along the west coast of the West 

 Bay. In 1899 a good-sized patch grew about the region of the mouth of 

 the steamer canal. It was not noted in 1900. Here the species ends except 

 for occasional plants.
