27 and later) it falls to the bottom and curls up in a peculiar 

 fashion, the leaves coiling up circinately, like fern-leaves, and it 

 thus winters over. It grows among a dense vegetation of spatter- 

 dock, milfoil and hornwort. 



696. HUMPED BLADDERWORT 



UTRICULARIA GIBBA L. 



Frequent in sand along the shore on the west side of Lost Lake. 

 A small, inconspicuous species. Noted in flower August 2, 1906. 



697. FLAT-LEAVED BLADDERWORT 



UTRICULARIA INTERMEDIA Haync 



Among the numerous bladderworts found in Lost Lake marsh 

 a few thought to be this were found close to shore. They were 

 quite rare, and did not reach the fine development noted in plants 

 collected at Eagle Lake in an adjoining county, where the species 

 reached great perfection. The Lost Lake plants were dwarfed and 

 not well developed. The plants are exceedingly variable in appear- 

 ance, the aquatic form with slender, inconspicuous leaves, the creep- 

 ing land form with broader, firmer, more conspicuous leaves, ar- 

 ranged symmetrically on each side of the stem. The bladders are 

 larger than in any others we have noted, and are white in color, 

 borne on leafless stems and usually along or under ground. We 

 never found any animal remains in them. The interior is beset 

 with large peculiar glands. 



April 25, 1901, growing in good shape, with large bladders, in 

 Green's marsh; May 19, first flowers seen; May 24, abundantly in 

 blossom. 



This species makes firm winter buds, much smaller than those 

 of macrorhiza. 



698. LESSER BLADDERWORT 



UTRICULARIA MINOR L. 



Abundant in the north end of Lost Lake and in the flat marsh 

 north of it. A small inconspicuous species. Noted in flower the 

 latter part of May and on through the summer. Winter buds 

 small, about the size of pinheads or a little larger. 



699. GREATER BLADDERWORT 



UTRICULARIA MACRORHIZA LeConte 



Common in Lost Lake, especially in the upper end, but not 

 growing in such great masses as in one of the Twin Lakes farther
