er Heliopsis. These 4 figured in my Autikon 

 11 to 14. 



ACMISPON Raf. Atl. jour, meanin- point 

 hooked. Differing from Trigonella, Bucer- 

 utes, Plaiycarpos and Lotus. Even Torrey 

 said that it ougiit to be a genus, and Bcntliam 

 unites It to Hosackia. 



CaHx deeply 5 cleft, vexillum and wings equal, 

 pod stipitate smootii strait, compressed,^ swelled 

 and hooked at the point. Leaves ternate, Silky. 



1. A. SERicEUM Raf Lotus do. Pursh, Tri- 

 gonella americana, Nut. T. E. well described 

 by Nuttal, flowers axillary, solitary, subsessile. 

 From Missouri to Carolina, rare, probably 2 sp. 

 blended : both seen dry. 



2, A. MULTiFLORUM Raf peduncles axillary 

 and terminal, multiflore nearly in a spike or um- 

 bel. Missouri. Is not the Carolina plant this ? 

 or a peculiar sp ! Which is the Hosackia pur- 

 sJiiana of Bentham ? The true Hosackia have 

 pinnate leaves, pods cyhndrical, keel rostrate 

 instead of the pods. 



ACNIDA of Linneus. Genus better known 

 since Michaux corrected account, copied by all 

 our botanists except Elliot. But the original 

 A. canahiJia L. is not known to our botanists; 

 they all mean that of Michaux. Linneus de- 

 scribed his species as follow. — A. canabiua. 

 Root flexuose, stem white, petiols purplish 

 smooth, leaves pinnate velutine.folioles 5 to 

 7 narrow acute^ spikes axillary foliose, fl. fem. 

 cal. 2phyl. 5 styles. In Virginia salt marshes. 

 Such a plant with pinnate leaves cannot be of 

 this Genus. Could Linneus have described the 

 leaves of another plant mixt with Acnida flow- 

 ers ? Could this be over again his Datisca hir- 

 /a found by no one since? Sir James Smith
