been called Discopleura by Decandole, my 

 P^ jtinceum disc. 1823 in West Kentucky is 

 perhaps a LeptocnuUs. My Thaspium teniiU 

 Joliuni R. herb, p 78 is neither of that G. nor 

 a Zizia, but probably an Arcliemera also. The 

 Ferula villoma which has been united to 4 or 5 

 genera, must perhaps form a peculiar one which 

 I have called Scadiasis. My G. Cyrtospermum, 

 Lomatium, Cymospermum, Osmorhiza, Ma- 

 rathrum or Adorion, have been either adopted 

 or illustrated by Decandole. I now pass to the 

 Eryngides that are a family distinct although 

 akin to this. 



813. STREBLANTHUS Raf. atL j. 1833 

 p. 149. Flowers monoical in separate heads. 

 Involucre 4-6phyle, folioles unequal entire, pho- 

 ranthe cylindrical papillose, male fl. in ovate 

 heads apetalous, calix 4fid,stamens 4 subsessile, 

 female flowers in oblong heads, calix adherent 

 4 dentate persistent, pistil obovate punctate, pe- 

 tals none or deciduous, styles 2 filiform persis- 

 tent, stigmas capitate. Fruit crowned biparti- 

 ble in 2 seeds convex scrobiculate. Annual 

 herbs smooth prostrate, leaves opposite sim- 

 ple, heads axillary, — This character is taken 

 from the first sp. but the G. probably contains 

 many sp, and may be modified to comprize 

 them : all the Eryngiums not perennial nor stiff, 

 nor with alternate stiff" leaves, must be examin- 

 ed well, and may perhaps belong here although 

 some sp. may be polygamous, others with 5 sta- 

 mens occasionaly. It forms now a striking G. 

 of Eryngides by the monoical apetalous tetran- 

 drous flowers. The Er, cervantesi of Mexico 

 E. tenue or gracile, halduini, prostratuni of 

 the Southern States may belong thereto. The 

 name means deceitful flowers.
