Doubtful or Transferred Species. 



M. AsCHENBORNii, Sch. Bip. in Koch, Wochenschr. vii. 407, collected 

 by Aschenborn in Mexico (?), is described merely as having deltoid-ovate 

 serrate leaves pubescent only upon the nerves and larger vein* beneath ; 

 the petioles thickened and pales straight. — Type in herb. Bot. IMuseum 

 Berlin. 



M. ATRiPLiciFOLiA, Klatt. See synon. of J/, ovallfolia, Sch. Bip. 



M. ATRIPLICIFOLIA, Sch. Bip. See synon. of M. patens, Gray. 



M. CLEMATiDEA, Hemsl. 1. c. 105. See synon. of M. KarwinsKi^ 

 Sch. Bip. below. 



M. CRENATA, Sch. Bip. in Koch, Wochenschr. vii. 407, collected by 

 de Berghes in Mexico without locality, is described as having stout peti- 

 oles and ovate crenate leaves 7.7 cm. long and 2.8 cm. broad, 3-nerved 

 from above the shortly cuneate base and tomentose beneath ; the pales 

 straight-pointed. — No plant satisfactorily corresponding to this species 

 seems to have been secured in recent years. 



M. ELEGANS, C. Koch, Wochenschr. vii. 408, Hemsl. 1. c. 165, of 

 unknown country and characterized only as to leaf contour, must be most 

 nearly related to if not identical with M. pyramidata, Sch. Bip., from 

 which so far as known it differs only in the absence of the inconstant 

 petiolar appendages. 



M. HERACLEIFOLIA, Brongn. See synon. of M. hipinnatijida, C. 

 Koch. 



M. HETEROPHYLLA, Hemsl. Biol. Cent. -Am. Bot. ii. 166, in syn. is a 

 clerical error for Eriocoma heterophylla, Schrad., which is 3L tonientosa,
