20 DE. H. F. hanoe's supplement to 



latter varies much, some species or varieties being delicately 

 aromatic, others disagreeably rank) quite constantly. It would, 

 however, be impossible, without a thorough review of the species 

 usually acknowledged, .and a comparison of copious suites of 

 specimens from variolis parts of the world, together with au- 

 thentic types, to determine the number, limits, and nomen- 

 clature of these ; and I therefore confine myself, ex rei necessi- 

 tate, to this statement. It is but fair to add that my views 

 as to the limits of species, or their legitimacy, would doubtless 

 often be repudiated by Mr. Bentham ; but I speak after pijo- 

 longed observation of these plants (in a wild state) growing 

 under precisely similar circumstances and in the same soils. 



♦Wedelia biflora, DC. in Wight's Contrib. Ind. Bot. 18 ; Bmtli. Fl. 

 Austr. iii. 539. (=Wollastonia biflora, DC. ; Benth. Fl. Honglc. 183.) 

 The species of Wollastonia vary so much as regards entire 

 absence of pappus, or its presence in the shape of a few deci- 

 duous bristles, that it is found impossible to retain the genus. 

 I have also seen achenes of Wedelia calendulacea, Less., entirely 

 without pappus. 



*Saussurea pulchella, Fisch., c japouica, v. Herder in Plant. Radd. 

 Monopet. 51. ( = S. japoniea, DC. ; Benth. Fl. Hongk. 167.) 

 Herr v. Herder has, I think, acted with great judgment in 

 reducing this and many other usually received species to the 

 rank of varieties. I had long been satisfied that no specific dif- 

 ference exists between the Hongkong and Amoy plant and 

 Amurian specimens of the pinnatifid foim which is the type of 

 S. pulchella. 



^Ixeris ramosissima, A. Gr. 



Under this name, I am inclined to think, two species are con- 

 founded — one a large branching plant, with large runcinate and 

 lyrate leaves narrowed into a petiole, the other with small 

 scarcely divided stem-clasping leaves, which is near I. sonchi- 

 Jblia, mihi (Youngia, Maxim.); but the specimens at h^nd are 

 not sufficient to enable me to characterize them satisfactorily. 

 Prof. Asa Gray remarks of his /. stolonifera (Mem. Amer. Acad, 

 vi. 397) that it is " doubtless the Youngia pygmma of Ledebour 

 and Zuecarini, as to their Japan plant, but not a congener ot 

 Frenam,tlies pygmaa, Ledeb. (Orepis nana of Eichardson), which 

 is apparentlya Orejpis." But this is too hasty an identification.
