Lake Maxinkuckee, Physical and Biological Survey 415 



north. Common in the ponds and ditches in Green's marsh; 

 abundant also in the outlet of Lost Lake near Walley's. It 

 forms considerable masses of vegetation in the lake, some of the 

 plants being over three feet long with numerous long branches. 

 It was found also in a permanent pond east of the lake north of 

 the Maxinkuckee road. The great number of bladders make it a 

 curious object. The bladders are usually light green, like the rest 

 of the plant, but in some cases they are dark purple, in which case 

 they are especially conspicuous. They are sometimes so deep a 

 purple as to be entirely opaque. 



The bladder is a curious contrivance bearing a remarkable re- 

 semblance in general outline to a water-flea (Daphnia), the long 

 bristles reaching out from the mouth resembling the anterior ap- 

 pendages of the crustacean. These bristles probably act as guides 

 to the trapdoor which rises easily to let small creatures through 

 but drops down after they have entered. 



700. RECLINED BLADDERWORT 



LECTICULA RESUPINATA (B. D. Greene) Barnhart 



Not common; a small patch found by the water's edge on 

 the east shore of Lost Lake below the Bardsley cottage. A dainty 

 little plant with attractive purple flowers noted in flower from the 

 middle to the latter part of August, 1906.

701. SQUAW-ROOT 



CONOPHOLIS AMERICANA (L. f.) Wallr. 



A plant of this species was seen in a gully northeast of the lake, 

 April 11, 1907. The yellowish, thick, cone-like growth forming 

 a dense spike of flowers and rising directly out of the root of an 

 oak, was a striking object. In some parts of Tennessee where this 

 plant is common it is known as "Devil's popcorn." 



702. BEECH-DROPS 



LEPTAMNIUM VIRGINIANUM (L.) Raf. 



Found quite abundantly on the east side of the lake, both in the 

 spring of 1901, April 6 and 11 (old last year's plants), and in 

 the winter of 1904.
