one. Florets five to eight. Pappus more. Seed smooth 

 and black. The genus has been recently formed by spren-

 appears to be allied to Chrysocoma.

Actinomeris * paucifiora, foliis oblongis serrulatis decur- 

 rentibus nudis paucifloris. 



Observations. — Stem apparently simple: Leaves op- 

 posite oblong or oblong ovate. Peduncle fevv-tlowered, 

 long and naked, (in my specimen, two-flowered. Calix 

 composed of about a simple series of lanceolate leaves. 

 Seeds winged on the margin, shortly two-horned. (Flowers 

 not seen.) 



SYNGENESIA.— Necessaria. 



Silphium * subacaule, scabriusculum : caule brevissimo, 

 pedunculis longissimis, foliis oblongis subsinuata-pinnatifi- 

 dis dentatis, calycinis foliolis dilatatis rhomboideis. 



Observations. — A species very remarkable for its dimin- 

 utive stature, the stem being often altogether wanting, and 

 at most but two or three inches high. Leaves sessile, al- 

 tern?^^, two or three inches long, with the margin alter- 

 natel) sinuated so as almost exactly to resemble the leaves 

 of some species of Senecio. Peduncle nearly a span long. 

 Flowers, as usual, yellow. The seeds also conformable 

 with the genus.
