Mitreola petiolata, Torr. & Gray occurred in the collection without 

 a number. Valeriana scandens, L. (357) is one of tlie commonest of 

 Tropical American plants. 



The Compositae of course are numerous. We have Vernonia Dep- 

 peana, Less. (46), V. Schiedeana, Less., ex Schultz Bip. (51), V. stri- 

 gosa, Schultz Bip. in coll. Linden, mixed with V. canescens, H. B. K. 

 (47), and V. liatroides, DC, which is 229 of Coulter's collection (70) : 

 also Elephantopus tomentosus, L. (79, 335) ; Elephantosis angustifolia, 

 DC. (60) ; Dlstreptiis spicatiis, Cass. (237) ; and Lagascea latifolia, 

 DC. (317). 



Pedis Seemanni, Schultz Bip. in Bot. Voy. Herald, p. 309 (137). 



Pedis latisquama, Schultz Bip. in coll. Mex. SchafFn., var. Berlan- 

 dieri : caule pedunculisque elongatis ; foliis interdum pinnatifido-denta- 

 tis ; involucri squamis minus latis spathulato-obovatis. — Pappus in the 

 ray commonly multisetose like that of the disk, but sometimes scanty. 

 This is no. 3159 of Berlandier's collection, from Nueva Leon (63). 



Ccelestina ageratoides, var. latifolia, DC, apparently C corymbosa, 

 DC. also (100). 



Isocarpha oppositifolia, R. Br., the Dunantia Achyranthes of De 

 Candolle (72). 



Stevia panicidata, Lag., DC, which is the S. rhomhifoUa and S. 

 origanoides, H. B. K., and S. nepetcefolia, DC. (Berlandier's no. 2273), 

 not of H. B. K. (50). 



Brichellia Cavanillesii, Benth., the same as no. 1247 of Berlandier's 

 collection (310). 



Eupatorium divergens, Less., which is probably no more than a va- 

 riety of ^. conyzoides (54) ; E. gracilijiorum, DC, from the character, 

 but the heads are 15-flowered (44) ; E. ivoefolium, L. var. ^. DC, 

 with the tips to the scales of the involucre green and decidedly squax*- 

 . rose-spreading; the same as no. 1948 of Fendler's Venezuelan collec- 

 tion (53) ; E. collinum, DC. (52) ; E. quadrangulare, DC, with the 

 flowers more developed than in Berlandier's collection from the same 

 district (340) ; E. pycnocephalutn, Less. {^E. Schiedeanum, Schrad. «fec.) 

 according to Dr. Schultz (57) ; E. Berlandieri, DC (56) ; and Crito- 

 nia daleoides, DC, or Eupatoriimi sessile, Schultz Bip. (88, 341). 



been overlooked. This rectification of the character leaves my genus Badusa to be 

 distinguisiied almost alone by the dorsifixed and at length versatile anthers, which 

 will hardly be deemed sufficient.
