 Walter, Lteptocaulis do N. Dec. Ammi do 

 Pers. and again Ligusticum pusillum Persoon! 

 (Elliot) Sison pusillum MX. Pursh, Elliot &c. 

 Annual slender smooth dichotome divaricate, 

 leaves triternate multipartite segments linear or 

 setaceous, umbel. 5-6fid, umbellules commonly 

 triflore, pedicels equal, invol. 3 lanceolate mi- 

 nute in Carolina and Florida, bipedal not hum- 

 ble, my specimens are in fruit, brown, realy 

 warty, hardly squamose. Here is a sp. put in 

 5 Genera! 



782. BABIRON DICHOTOMTJM R. Ammi divar-

 short bipinnate, segments narrow linear, umbels 

 2-4 fid, umbelules 3-5flore, pedicels unequal, in-

 than the last, but stem terete not striate nor sim-

783. DAUCUS SCADIOPHYLUS Raf. stem grow- 

 ed retrose pilose, leaves few short tripinnate 

 hirsute, segments linear acute ; involucres 5-6 

 foliose bipinnate \ partial simple as long as 

 flowers, petals equal not radiate seeds hispid. 

 Florida, Alabama and Georgia, a Southern 

 Daucus so unlike the others, as to be almost a 

 N. G. I shall form a subgenus of it (with the 

 next) GINGIDIUM with involucres bipinnate pe-

 involucres nearly similar to the leaves, flowers 

 small, seeds oblong hispid between the muricate 

 ribs. D. Lucidus, being the same as D. gin-
