169. HYDROPELTIS. 



HYDRQPELTIS PURPUREA. Mich. Water target, 



Syn. IXODIA pADUsfRis. Solander. 



JBRASENIA HTDROPELVIS. Muhl. 



An aquatic plant, the only species of its genus. Its leaves 

 whcih can hardly be mistaken for any thing else, are perfectly 

 elliptical, with the leaf stalk inserted exactly in their centre, 

 forming a centro-peltate leaf. Their upper surface is smooth 

 and shining, like those of the water lilies, among which they 

 float. Flowers dark purple ; petals six, the three outermost 

 shortest. Stamens numerous. The immersed portions of the 

 plant, particularly the stalks and young leaves are cloathed 

 with a thick gelatinous substance, transparent, and insipid to 

 the taste. In Fresh pond, and other stagnant waters. July. 

 Perennial. 



170. ANEMONE. 

 ANEMONE HEPATICA. L. Early Anemone. 



Leaves three lobed, entire. L. 



It is a circumstance not a little perplexing to students, tha' 

 the first plant in a genus without a calyx, should have a calyx 

 of three leaves. Linnaeus in associating this plant with the an- 

 emonies, considered the calyx from its remoteness, to be an in- 

 volucrum and not a perianth. Leaves radical, on hairy petioles, 

 with three broad oval lobes. Peduncles and involucre hairy. Pe- 

 tals red. This elegant little plant is one of the earliest visitors 

 in spring, flowering in sunny spots before the snow has left the 

 g-round. Woods, Cambridge, Roxbury. April. Perennial. 



ANEMONE NEMOROSA. Mich, Wood Anemone. 



Seeds pointed ; leaves three : leafets lolied ; 

 stem on& flowered,
