distinct, and in some respects much resembles V. sericea (Harpalhim 

 sericeum, DC), of Peru. The dense and rigid ciliation of the involucre 

 is characteristic. 



ViGuiERA iiELiANTHOiDES, ITBK. Adopting Bentham's reference 

 of DeCandolle's V. laxa and V. brevipes to this, the original of the ge- 

 nus, one may confidently add V. SagrcBana and V. dentata, perhaps all of 

 DeCandolle's first section, and at least two of the second. V. deiitata, 

 the Helianthus dentatus, Cav., appears to be well matched by Parry & 

 Palmer's no. 47 h}, and by corresponding specimens from Schaffner, 

 with upper leaves mainly opposite ; also, although the leaves are alter- 

 nate, by Parry & Palmer's 467, and Bourgeau's 365 and 1222, which 

 Hemsley records as two undetermined species. (No. 1222 has rays in 

 one of our specimens.) In no specimens, even the Cuban, do I find 

 the receptacle so high and narrow as in Kunth's figure ; and at first 

 the disk is commonly so low that DeCandolle referred some of the 

 members of this species to his second section. When growing in 

 moist soil and shade the leaves are thin and green (as in V. Texana, 

 Torr. & Gray), in drier and more exposed situations they are thicker, 

 smaller, rather rigid, sometimes cinereous, as in V. brevipes. 



ViGuiEKA CANESCENS, DC, although near the preceding, appears 

 to be a distinct species, having more rigid leaves and akeues whitened 

 by a dense and fine silky villosity. It has been collected by Palmer 

 in Northern Mexico, and by Pringle in Arizona. 



ViGUiERA Ghiesbregutii. Uudiquc hispidula; caulibus gracili- 

 bus oligocephalis ; foliis lanceolatis subintegerrimis concoloribus leviter 

 triplinerviis subsessilibus, inferioribus oppositis ; capitulis iis V. buddlei- 

 formis minoribus ; involucri bracteis paucioribus minus patentibus, 

 extimis brevibus lanceolatis, intimis oblongo-spathulatis discum sub- 

 superantibus ; ligulis linearibus ; acheniis (immaturis) fere glabris ; 

 pappo pluri-squamellato et 1-3-aristato deciduo. — Mexico, in pine 

 forests near Morelia, Ghieshreght^ no. 381 of an old collection. 



ViGuiERA sessilifolia, DC. We seem to have this in no. 453 of 

 Parry & Palmer's collection. But the truncate palese are more than 

 four, unless they are early fissile. No. 458 of the same collection 

 seems to be a broad-leaved form of V. excclsa, Bcnth. & Hook. No. 

 452 is, with little doubt, a state of V. cordifolia, Gray. 



ViGDiERA Peruviana, Gray, Proc. Am. Acad. v. 124, appears to 

 be only a glabrate state of IMianthtis aureus, HBK., the Harpalium 

 aureum, DC.
