III. ON SOME HITHERTO UNDESCRIBED OR MISPLACED 



COMPOSITAE. 



Microglossa mespilifolia (Less.), comb, nov. Aster mespilifoliiis 

 Less. Syn. Conip. 180 (1832). Nidorella mespilifolia (Less.) DC. Prod, 

 v. 321 (1836). Microglossa mesplloides Benth. & Hook. f. Gen. ii. 

 282 (1873), without express combination and with obvious clerical 

 error as to the specific name; Hook. f. & Jacks. Ind. Kew. ii. 229 

 (1895). 



Psiadia Boivini (Klatt), comb, nov, Pluchea Boivlni Klatt, Ann. 

 Sci. Nat. ser. 5, xviii. 369 (1873). As suspected by Cordemoy, Fl. de 

 rile de la Reunion, 526 (1895), this species proves on examination of 

 Dr. Klatt's type (now in the Gray Herbarium) to have the characters 

 of a Psiadia and not of a Pluchea. The anthers, for instance, are en- 

 tire and rounded at the base and not caudate. Whether or not Cor- 

 demoy's Psiadia Frappieri may prove a synonym is a point which 

 cannot be determined from description alone. In any event, however, 

 the earlier specific name of Klatt would have to prevail. 



Pluchea rubelliflora (F. v. Muell.), comb. nov. Eyrea ruhelUfiora 

 F. v. Muell. Linnaea, xxv. 403 (1852-53). Pluchea EyreaY. v. Muell- 

 Rep. Babb. Exp. 11, 12 (1858); Benth. Fl. Austral, iii. 528(1866). 

 — The restoration of von Mueller's earlier specific name becomes neces- 

 sary under the International Rules of Nomenclature. 



Rutidosis multiflora (Nees), comb. nov. Styloiicerus multlflorus 

 Nees in Lehm. PI. Preiss. ii. 244 (1846-47). Pumllo argyrolepis 

 Schlecht. Linnaea, xxi. 448 (1848). Actinopappus perpusillus Hook. f.
