Wing-stemmed Mexican species known to me are,— - 



V. ovATA, Coreopsis ovata, Cav. Ic. t. 280, mentioned under Acti- 

 nomeris by Nuttall, taken up by DeCandolle, and seemingly known to 

 recent botanists only by Coulter's no. 362, which is described by Hems- 

 ley. It is more polycephalous than the figure, and the leaves of .both 

 specimens and figure are oblong, not ovate. 



V. TETRAPTERA. Corcopsis alata, Cav. Ic. iii. t. 260. Helianthus 

 tetrapterus, Ortega, Dec. vi. 74. Pterophyton alatu7)i, Cass. xliv. 49. 

 Actinomeris tetraptera and probably also A. tetragona, DC. Prodr. 

 V. scabra, Benth. PI. Hartw. 41, is said to belong here. 



V. CouLTERi. Bipedalis e radice perenni, pube molli cinerea ; 

 caule inferne foliato alato superne gracili longe pedunculiformi mono- 

 oligo-ceplialo; foliis plerisque oppositis obovatis vel sjiathulatis sub- 

 serratis supra puberulo-scabridis subtus canescentibus, summis brac- 

 teiformibus minimis linearibus ; capitulo hemisph£erico lin. 3 alto ; 

 involucri bracteis biseriatis lanceolatis a^quilongis ; ligulis circa 12 

 oblongis styliferis, tubo etiam corollis disci hirsutissimo ; ovariis pilosis 

 biaristatis. — Zimapan, Mexico, Coulter, 341, 369. 



V. Capitaneja, Nees in Linnoea, xix. 729. Actinomeris peduncu- 

 losa, DC, Prodr. v. 576 ; a somewhat common species. The popular 

 name " Capitaneja," according to Schaffuer, is applied to V. tetraptera, 

 probably to other species. 



V. NERiiFOLiA, Hemsley, no. 528 of a collection of Ghiesbreght 

 ' distributed from our herbarium, and V. Oaxacana, DC, which Hems- 

 ley informs us is quite different, belong to a peculiar group, perhaps 

 to be associated with V. hypoleuca. 



Species of Mexico known to me, of the naked-stemmed group, 

 are, — 



V. HYPOLEUCA, Gray, Proc. Am. Acad. xx. 37. 



V. STRiCTA. Actinomeris stricta, Ilemsl. Biol. Centr.-Ara. Bot. ii. 

 186. The ray -flowers are not rarely styliferous and even form akenes, 

 but wingless and probably infertile ones. Besides the collections 

 cited by Hemsley, this is Schaffner's 343, also Palmer's 627, 628. 



A peculiar species from the Mexican dominion is, — 



V. VENOSA, E. L. Greene in litt. Fruticosa, fere glabra et la^vis ; 

 ramis immarginatis ; foliis oppositis alternisque chartaceis ovatis et 

 ovato-lanceolatis cuspidato-acutis subintegerrimis triplinerviis reticu- 

 lato-venosis utrinque viridibus minutissime scabridis basi in petiolum 

 marginatum subito contractis; capitulis pauciusculis laxe cymoso- 

 paniculatis ; involucre campanulato lin. 3 alto disco breviore, bracteis 

 oblongis lanceolatisque adpresso-imbricatis triseriatis, exterioribus bre-
