Largest Bladder-wort. Horn-wort-leaxed Hooded 



Milfoil. 



This very singular plant, is described by Mr. Nuttall, as the 

 largest American species- It is much larger in the southern 

 states than here. Hitherto I have detected it in a single 

 place, and though there extremely abundant, covering the 

 surface of a large pool ; it seldom attains a much greater size 

 than No. 2. Readily identified by the four or six long, inflated, 

 fimbriated leaves which proceed from the base of the scape, 

 and support the plant on the surface of the water. Flowers 

 yellow and here, about the size of those of No. 2- In a stag- 

 nant pool, situated in a wood about half a quarter of a mile 

 east of the tew last houses of the south end of the village of 

 Woodbury, Jersey. Perennial. July, August. 



3. U. nectary gibbous and keeled ; the mouth of minor, 

 the corolla open. Vahl. Willd.

Flowers deep yellow, but smaller than those of No. 2. In 

 shadi d swamps, and similar places with U. vulgaris, in Jer- 

 se>. Rare. I have n ver found it on the Pennsylvania side of 

 the Delaware. Perennial. August. 



4. U. nectary gibbous ; the segments of the corolla £ ibba * 

 roundish ; scap o le-fl nvered. Willd. 



A small species, perhaps never exceeding one fourth the 

 size of eithci of the preceding. Flowers smaller than in No. 

 3, and lighter yellow. In quagmire bogs ; and in shallow 

 stagnant pools. In the Neck, about a mile from the city, and 

 no great distance fr«m the Delaware. Very abundant near 

 the spot where the Cyamus rlavicomus grows. Often floating,
