PLANTS GROWING IN MUD. 67 
MARSH CLEMATIS. (Piate XXV/Z) 
Clémates crispa. 
Perhaps the most beautiful of our native species is the blue 
clematis of the marshes. Its large, solitary, nodding flowers, 
which are gracefully shaped, and silky styles, give it a delicate, 
quaint appearance that is full of charm. Unfortunately, it is 
little known outside of the territory between southeastern Vir- 
ginia, Florida and Texas. It blossoms in May and June, and 
has a delightful fragrance.

Often in cranberry bogs and in the marshes we will find this

HORNED BLADDERWORT. (Plate XXV///.) 
Utricularia cornita. 
Among the aquatics (page 34, Plate VIII) we have already 
acquainted ourselves with a curious connection of this pretty 
plant. U.cornuta we find in peat bogs; it does not bear any 
bladders and is therefore less extraordinary in its movements. 
On a slender pedicel it bears from two to four large flowers 
about one inch long, which have a helmet-shaped lower lip and 
long curved spur. They are bright yellow, delicate, and very 
fragrant. In fact, Mr. Burroughs regards this to be the most 
intensely fragrant wild flower of our country.
