Michoacan or Guerrero, Mexico, alt. 300 m., 20 October, 1898, H. Lan- 
glassé, no. 482 (type, in hb. Gray). A species related perhaps most 
nearly to M. microcephalum Less., which, however, is described as having 
leaves sessile by a much narrowed base. There is nothing furthermore 
in Lessing’s description of the achene to suggest that he had before 
him the peculiar fruit of the present species. :

ico, 5 January to 6 February, 1892, Dr. Edward Palmer, no. 1814 (type 
in hb. Gray). This species should stand nearest to M. arvense Robins0b; 
but it is readily distinguished from that species by its leaf-form, the — 
shape of the rhombic-ovate bracts, the more numerous ray-flowers, ete. 
Jaegeria glabra (Wats.), n. comb. Sabazia glabra Wats. Proc. # 
Acad. xxiii. 277 ( 1888). Jaegeria petiolaris Robinson, / 
Acad. xxxv. 316 (1900). When this species was transfe wees 
years ago to Jacgeria its specific name was changed owing to the exist 
ence of J. hirta, var. glabra Bak. in Mart. Fl. Bras. vi. pt- 3, 167 (1884): 
According to the Vienna rules, however, the existence of a vat 
hame in a genus is no obstacle to the use of the same name 12
