 It had previously been recorded from only one locality in the state, 

 in Lake County, and was found about the same time by Mr. W. S. 

 Blatchley in some abundance in Cedar and Mud lakes near South 

 Bend. Winter buds were collected during the winter of 1900-1901 

 and a few were found in the same region in the early winter of 1904 

 and on subsequent occasions. An attempt was made to keep some 

 of these plants in a small aquarium but they did not thrive. Under 

 suitable conditions they should do so and would make very desir- 

 able plants for aquariums. Strictly speaking, this species does not 

 form winter buds, as most of the bladderworts do. The short 

 young upper leaves and branches simply coil up circinately after 

 the fashion of fem buds, or the sundew, and remain in that condi- 

 tion until the growing season in spring. 



This is one of the most graceful species of the genus, the whorled 

 arrangement of the branches giving it the general appearance of 

 a charad. The effectiveness of the rather small bladders as animal 

 traps was not investigated. 



3. GREATER BLADDERWORT 



UTRICULARIA MACRORHIZA Leconte 



Very common in the north end of Lost Lake, making consider- 

 able masses of vegetation ; abundant also down the outlet of Lost 

 Lake near Walley's. Common in the shallow ponds and ditches of 

 Green's marsh, and found in a permanent pond east of the lake 

 north of the Maxinkuckee road. Not nearly so abundant in the 

 Lake Maxinkuckee region as in Twin Lakes a few miles farther 

 north, where they grow in great abundance and most luxuriantly 

 in one of the lakes. 



The plants begin rather early in the autumn (September 17, 

 1900) to form hibernating buds which vary in size from that of a 

 pea to that of a good-sized marble. The upper leaves of the plant 

 coil up into an exceedingly firm ball, the lower leaves are shed, leav- 

 ing the propagating buds at the end of a long delicate looking 

 slender string, which looks easy to break but proves exceedingly 

 tough and strong. The stem decays during the winter. The win- 

 ter buds are held together by a sort of gluey secretion. They prob- 

 ably, most of them, sink to the bottom and remain all winter. How- 

 ever, in the winter of 1904, great numbers were found half sticking 

 up out of the ice and half buried in it. 



Winter buds placed in water in a warm room appear to behave 

 differently, probably according to whether the bud was taken in its
