397. Coreopsis tinctoria, Nutt. East of Mora River, in low places ; Aug. 

 (441) ; and (442) between Coon Creek and Pawnee Fork, in shallow hollows in the 



summis altemis, petiolo immarginato basi auriculato ; involucri cano-villosi squamis a:quilongis; lignlis 8-10 

 brevibus ; acheniis glabris marginibus superne ciliolatis apice emarginata aristellis 1 vel 2 minimis donatis vel 

 abortu vix bidentatis ! — Bishop's Hill, near Monterey, Dr. Gregg; flowering in February. — The speci- 

 mens, probably depauperate, are only a span high. The awns at most are not longer than half the breadth of 

 the achenium, or the proper tube of the corolla ; one of them is almost always abortive, and often both are 

 reduced to a mere vestige. This species, therefore, invalidates the character of the genus Barrattia, Gray fy 

 Engelm., which well accords with Simsia in habit ; and which, although the absence of pappus would refer it 

 to a different Candollean division of Heliantheas, I fear cannot be maintained as a separate genus, after the 

 discovery of the present species. At most, it differs from Simsia only as Coreopsis involucrata does from 

 C. aristosa, and Actinomeris (Achseta) pauciflora from genuine Actinomeris. — The genus Gersea, Torr. <^ 

 Gray {Proceed. Amer. Acad. 1. p. 48), must also be reduced to a section of Simsia. 



S S. (Gerxa; achenia, et aristse palasoliformes inferne, villosissima) canescens : caule basi foliato simplici 

 superne longe nudo 1 -3-cephalo; foliis incano-hirsutissimis alternis vel imis subrosulatis obovatis rhombeisve 

 ssepius integerrimis basi trinervatis subsessilibus, summis ad bracteas parvas reductis, involucri triserialis 

 squamis villosissimis ; ligulis maximis cuneato-obovatis apice subtrilobis tubo piloso gracili discum sequante 

 stipitatis ; acheniis oblongo-cuneiformibus pilis argenteis proesertim ad margines longissimis villosissimis ; aris- 

 tis lineari-subulatis corollam subaequantibus. — Interior of California, Fremont, Coulter. 



From Texas Mr. Wright sends an Actinomeris with nearly awnless achenia, but which has not decurrent 

 leaves as in Nuttall's A. (Achseta) pauciflora, and connects that anomalous species with the section Apteron. 



S Actinomeris Wrightii (sp. nov.) : caulibus gracilibus undique foliosis apice subcorymbosis ; ramis pau- 

 cis superne nudiusculis monocephalis ; foliis oppositis summisve alternis ovatis grosse serratis triplinerviis 

 crassis utrinque scaberrimis basi cuneatis vel abrupte angustatis sessilibus haud decurrentibus plerisque inter- 

 nodiis duplo longioribus ; involucri hemisphserici squamis ovalibus obtusissimis 3-4-seriatim imbricatis disco 

 fruclifero convexo brevioribus; receptaculo convexo ; ligulis 9-12 elongatis; acheniis oblongis lato-alatis 

 apice emarginato nudis, aristis rudimentariis dentiformibus alae adnatis. — Mountains near Austin, Texas; 

 Sept. Mr. Wright. — Stems many from the same root, two or three feet high. Leaves from 2 to 4 inches 

 long ; those of the short flowering branches small, obtuse and alternate. Heads larger than in A. helianthoi- 

 des. Rays golden-yellow, an inch long. Achenia 4 lines in length. 



Among the novelties gathered in the mountains about Cosiquiriachi by Dr. Wislizenus, a striking Helian- 

 thoid plant occurs, which I refer to Tithonia, viz. : — 



/ Tithonia decurrens (sp. nov.) : pube molli subdecidua undique cano-villosa ; caule robusto ad apicem 

 usque foliosissimo ; foliis ovato-lanceolatis acutis subintegerrimis penninerviis basi decurrentibus supra 

 demum glabratis scabris ; pedunculo cylindrico capitulo subgloboso breviore ; involucri biserialis squamis 

 ovato-oblongis appressis apice brevi foliaceo patentibus discum vix aaquantibus ; paleis receptaculi convexi 

 rigidis apice truncato bimucronatis ; acheniis disci sericeis 2-aristatis ; aristis subulatis squamellisque crassis 

 persistentibus. — On the Bufa ; common on the mountains around Cosiquiriachi, in the State of Chihuahua, 

 Dr. Wislizenus ; Oct., in fruit. — Herb 2 or 3 feet high, stout. Leaves 4 to 8 inches long, sessile and 

 strongly decurrent, not triplinerved, but the primary veins confluent into an intramarginal vein, hoary beneath 

 with a villous, above with a short and soft, pubescence, which is readily detached by rubbing. Heads termi-
