Jtoo/ perennial, branching,--of a sweetish, mawkish taste,- and not the pleasant 

 an'i8ate flavor of the preceding. It more resembles that of At alia nudicattlis as 

 Dr. BigeloiD remarks. Stem about 2 feet high, mostly fistular, branching, striate, 

 pale green, smooth below, pilose above, especially at the base of the branches and 

 the margins of the sheathing petioles; stem often branching from the root \radical 

 leaves 1 or 2, on smooth green common petioles D to 19 inches in length. Leaves 

 blternately decompound ; petioles and leaflets pilose with lunger and Btraigij 

 hairs than in the preceding species; the leaflets gem rails larger (smaller, Hook ) 

 more membranaceous, and more deeply incised, often piunatifid, l mbels nearll 

 as in the preceding,— but the rays rather longer, and the mvolueek not quite se 

 large. Petals white. Fruit somewhat clavate, or nearly lance-oblong, crowned 

 with the c mical base of the very short parallel conic styles, and attenuated below 

 Xs> a slender stipe, or cauda, which is clothed with apprcssed bristles.

Obs. This certainly has a strong general resemblance to the foregoing,— but if 



fry no means so common, in this vicinity ;— nor have the? yet been found growing 



in company. It was first observed, here, in i :>{.•, by Mr. ( hkvnev Hannum. The 



tlistinctiTe characters of the two sp ies are obvious enough, when the attention is 



directed to them (winch appears first to have been done by Dr. Paine, of Geneva, 



V. Y.); hut they ere s blended, in the deseriptUms of Auth rs t that it is not easy t* 



disentangle them, and settle the synonyms. \V th the aid of my friend Mr. Josh. 



.wa Hoopes, who collected several fine specim tna of each, I have endeavored to 



.give the distinguishing cl aracteristics, as they appear in thcChcster County 



plants. The difference in the taste of the r«k is quite striking ; and my observa- 



lions agree better with Dr. I3igelow% than with those of Dr. Torrey. No olhtr 



-species are known, in the U. States.
