PLANTS GROWING IN MUD. 67 



MARSH CLEriATIS. {Plate XXVII.) 

 Clematis 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. 



MARSH ST. JOHN'S-WORT. 



Triadhium Vh-orinicum. 



Flowers : small ; axillary ; terminal; in close clusters; growing singly or in 

 pairs. C^/j'j; ; of five, flesh-coloured sepals. Ccrf/Za ; of five petals. Staifiens : 

 nine to twelve, in sets of three ; each set separated by a yellow gland. Pistil : 

 one, with three styles. Leaves : opposite, in pairs united about the stem ; ob- 

 long ; not tapering at either end. Slem : erect ; brightly coloured. lod : deep 

 red. 



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

 pretty plant upholding the honour of the St. John's-wort. 



HORNED BLADDERWORT. (Plate XXVIII.) 

 Utricularia coniuta. 

 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.
