stem angular and leaves capillary, Michaux 

 says like Fennel. My plant is not such, but 

 they may have seen bad specimens. 



Genus DAUCUS and akin. 

 Here is a striking instance of the blending 

 propensity of our Botanists, who do not take 

 care to look sharp, overlooking the most evi- 

 dent characters. I can speak with confidence, 

 since I did the same for 20 years concerning 

 our wild Carrots, until at last having noticed 

 some kinds with bipinnatijid involucres and 

 others with entire involucres^ I was led to no- 

 tice observe and revise the genus and akin. It 

 had even been supposed that our Carrots were 

 naturalized, while they are found native in the 

 wildest localities. My researches have already 

 led me to ascertain 3 genera and a dozen spe- 

 cies, all probably deemed D. carotta or pnsil- 

 lus when seen by others. I'he nature of the 

 involucres and seeds is essentialy generic here, 

 else DciKCUs and Caucalis should be only one 

 Genus. The G. Dasyspermum 295 of Necker 

 which he says had a fruit hispid muricate all 

 over, includes also several, since it was formed 

 out of Tordyliuni,Conium, Ammi and Scandix ! 

 having muricate seeds. 



776. DAUOUS Raf. involucres pinnate or 

 multifid, partial with entire or trifid folioles. 

 calix 5tc)othed, petals obovate emarg. inflexed, 

 outer often larger radical unequal, heeds with 

 4 aculeate v.ings. Leaves decomposed^ floic- 

 ers white or red. — This is the type to which be- 

 long the real Carrots : I must now add here for 

 contrast all the Genera blended thereto. For 

 the sp.see 783 to 792. 



777. TIRICTA Raf. involucres simple 

 polvphyle, partial similar, flowers polygamous
