Prangos Hay Plant, f 



must be considered utterly subversive of analytical division, and 

 can only lead to a return to the genera of Umbelliferae as Linnaeua 

 left them. 



Besides Krubera and Rumia, the distinctions between which 

 and Prangos I have already explained, there is a third genus in- 

 cluded in Cachrys by Sprengel, but separated by Professor Link, 

 under the Bauhin's name of Hippomarathrum. From this Prangos 

 seems principally to differ, in having entire, not pinnatifid, invo* 

 lucra, the juga \^anged, not rounded, and the petals lanceolate, 

 not round with a broad involute segment ; all points of great im- 

 portance in characterizing umbelliferous plants. 



Having thus shewn that the Prangos Hay Plant is strictly re- 

 ferable to no genus of Umbelliferae at present constituted, I pro- 

 pose here to establish it with the following name and character:— 



PRANGOS. 



Char. Nat. — Calyx quinquedentatus. Petala sequalia^ lanceolata, incurva, 

 integerrima. Discus camosus, crispus. Achenia a dorso compressa. Peri- 

 carpium suberosum : commissura plana, angusta ; jugis quinque primariii 

 alatis, secundariis nullis. Semen multivittatum. Albumen involutum. — Herbae 

 Asue temperaiiB. Involucra umversalia et partialia simplicia, polyphylla* 

 Flores abortu monoid, lutei ? Folia supradecomposita. 



Among the plants placed by Sprengel under his genus Cachrys, 

 is the Laserpiiium ferulaceum of Linnaeus, found in the Crimea, ft 

 climate not very different from that of Draz, and described by 

 Marschall von Bieberstein under the name of Cachrys alata. This 

 having a winged corky fruit, like that of Prangos, and other^vise 

 agreeing with it in character, the genus now established will con- 

 sist of two species, which may be distinguished thus : —
