III. ON SOME HITHERTO UNDESCRIBED OR MISPLACED 
COMPOSITAE. 
Microglossa mespilifolia (Less.), comb. nov, Aster mespilifolius 
_ Less. Syn. Comp. 180 (1832). Nidorella mespilifolia (Less.) DC. Prod. 
Vv. 321 (1836). Microglossa mespiloides Benth. & Hook. f. Geri. 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 Boivini Klatt, Aun. 
Sci. Nat. ser. 5, xviii. 369 (1873). As suspected by Cordemoy, Fl. de 
V'Ile 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 Pluchkea. 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 rubellifiora (F. v. Muell.), comb. nov. Eyrea rubelliflora 
F. vy. Muell. Linnaea, xxv. 403 (1852-53). Pluchea Eyrea F. 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 multifiora (Nees), comb. nov. Styloncerus multiflorus 
Nees in Lehm. Pl. Preiss. ii. 244 (1846-47). Pumilo argyrolepis 
Schlecht. Linnaea, xxi. 448 (1848), Actinopappus perpusillus Hook. f.
