been called Discopleura by Decandole, my 

 Pt. junceum disc. 1823 in West Kentucky is 

 perhaps a Leptocnulis. My Thaspium tenui- 

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

 a Ziizia, but probably an Archetnera also. The 

 Ferula villosa which has been united to 4 or 5 

 genera, must perhaps form a peculiar one which 

 I have called Scadiasis. My G. Cyrtospermnm, 

 Lomatium, Cymospermum, Osmorhiza, Ma- 

 rathrum or Adorion, have been either adopted 

 or illustrated by Decandole. I now pass to the 

 EKYNGIDES 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^ balduini, prostratum of 

 the Southern States may belong thereto. The 

 name means deceitful flowers.
