parvulis sessilibus integerrimis ; capitulis longe pcdunculatis parvulis ; 

 involucri bracteis ovatis ; aclieuiis obovato-orbiculatis aiigu.sto-alatis 

 apice paruin emarginatis. — Mountains of Eastern Tennessee, near the 

 Tunnel at Cowan, Franklin Co., on limestone, Dr. A. Gallimjer, coll. 

 July 14, 18G7. By a singular mischance this very distinct Silplnum 

 was not made known to me until after the publication of the Com- 

 posita) in my Synoptical Flora. A subdivision should be provided for 

 it, to follow that which contains S. perfoUatum. The cauline leaves 

 are G to 10 inches long, on petioles of 1| to 2 inches; the small and 

 remote leaves of the slender flowering branches are only an inch or 

 two in length, (he 1-3-flowcred peduncles 3 or 4 inches long and 

 almost filiform. Involucre little over half an inch high. Kays ratlier 

 few, half an inch loiiij. Akenes 4 lines lonir. 



Franseria flexuosa. Acantholcena, F. deltoidcce affmior, frutes- 

 cens, canescens, mox glabrescens ; ramis gracilibus flexuosis ; foliis 

 deltoideo-lanceolatis vel basi breviter cuneatis brevipetiolatis attenu- 

 ato-acuminatis parce spinuloso-dentatis laciniatisque ligidis transverse 

 penniveuiis e costa valida subtus reticulatis ; panicula aphylla ; in- 

 volucris fructiferis brevi-ovoideis 2-3-floris (lin. 2-3 longis) pubes- 

 centibus aculeis paucis (7-8) validis subulatis e basi lata niox recurvis 

 (apice recto) armatis. — Canon Cantillas, within the borders of Lower 

 California, Orcutt, 1884. The foliage is somewhat like that of F. 

 ambrosioides, but with the rigidity of F. ilicifuUa. yet the teeth or 

 lobes of the leaves are hardly spinesceut. The fruit is that of the 

 Acantholcena section of the genus, its spines thicker than those of F. 

 deltoidea, and beset with short pubescence. 



IIelianthus tepiikodes, Gray. Annuus; caule ramoso j)l. m. 

 hispidulo ; foliis ovato-lanceolatis seu ovato-oblongis subintegerrimis 

 (circ. pollicaribus) longius petiolatis utrinque ramisque ])ube sericeo- 

 strigosa incanis ; involucri (lin. 4-5 alti) bracteis lanceolatis sub- 

 acuminatis fere jequilongis ; receptaculi paleis subintegerrimis acutis 

 plerumque glabris ; acheniis lineari-oblongis vel subclavatis turgidis 

 (parum compressis sericeo-i)ilosis vel inferne glabratis); pappo caduco 

 e squamellis 2 oblongis vel linearibus pilis apicalibus achenii aut brevi- 

 oribus aut longioribus. — Bot. Mex. Bound. 90. Viguiera nivea, Gray, 

 Bot. Calif, i. 354, excl. syn. V. tephrodes, Gray, Syn. FL ii. 271.

 ii. 2G9. — Complete specimens, with some mature fruit, from " sand- 

 hills in N. TV. Sonora, near the Gulf," coll. Pringle, 1884, now at 

 length fix this species under the name which I first applied to very 

 scanty and imperfect materials, and show that what were taken for fine
