glandulosisque, interioribus discum adsequantibus ; floribus luteis, ligu- 

 lis 10-12 oblongis (subtus li'vidis ?) ; paleis receptaculi cuspidato- 

 acuminatis ; acbeniis (immaturis) oblongis glaberrimis apice truncatis 

 calvis. — Mountain forest near Chiapas, S. Mexico, Ghiesbreght, no. 

 568, of recent distribution; very scantily collected. Branches slender, 

 glandular-scabrous and beset with spreading villous or hirsute hairs. 

 Leaves one or two inches long, the pubescence appressed, that of the 

 lower surface especially soft and satniy. Involucre half an inch high. 

 Rays barely half an inch long. Mature akenes not seen ; the imma- 

 ture ones flat, truncate at summit, not at all emarginate or bidentate. 



Coreopsis Linn. In the Genera Plantarum this genus is probably 

 extended too far when made to comprise groups of species with fertile 

 rays. At least in the Flora of California I am constrained to rein- 

 state two genera which are peculiar to that region, and in which no 

 true Coreopsis occurs, although, indeed, the genus does cross the 

 Rocky Mountains and reach the Pacific in a single species farther 

 north. As to the African section Prestinaria, it might be associated 

 with, or form a part of Diodonta. Epilepis Benth., the rays of which 

 are said in the Genera Plantarum to be fertile, but are more correctly 

 described in Plantse Hartwegianre as neutral, and those opposite-leaved 

 South American species which I once associated with Agarista, I should 

 still regard as belonging to Coreopsis, while I would re-establish the 

 California genus, under the name of 



PUGIOPAPPUS Gray. 

 Capitulum multiflorum, heterogamum ; floribus radii 7-10 fere 

 semper fosmineis, disci hermaphroditis. Involucrum duplex Coreopsidis. 

 Receptaculum planum, paleis scariosis cum fructu deciduis onustum. 

 Ligulae lata?, truncate, plurinervias. Corolla? disci tubo tenui versus 

 apicem annulato, limbo ampliato 5-lobo. Styli fl. radii breves, nunc 

 intra tubum ligulas retracti ; fl. disci ramis cono brevissimo superatis. 

 Achenia plano-obcompressa, ovalia vel oblonga, radii glaberrima, mar- 

 ginata vel alata, calva ; disci villosa vel ciliata, cum palea receptaculi 

 adpressa basi cohrerente decidua, pappi aristis paleolisve longis trique- 

 tris pugioniformibus superatis. — Herbse annua?, California?, glaber- 

 rima, foliis alternis 1 - 2-pinnatipartitis, lobis linearibus, capitulis 

 solitariis longe p^lunculatis, floribus aureis. — Agarista DC. Prodr.
