MAGALLANA Cav. 



P. 544 : 



This genus is not named in the list of Tropceolacece in Engler & Prantl, 

 die Naturl. Planzenfamilien, III, 4, though it was clearly described by 

 Cavanilles. Recently, in Spegazzini's papers, Plant, nov. Amer. merid. 

 Decad., I., p. 6, and Nov. Add. Flor. Pat., Ill, p. 256, detailed descrip- 

 tions of this monotypic genus are furnished, whereby its generic rank, as 

 distinct from the genus Tropceohim is further established. Nevertheless 

 the Nachtrage III, p. 181, of Engler & Prantl's work cites Magallana as 

 synonymous with Trop&olum. I may also refer to E. Autran, les Tropeo- 

 lacees Argentines et la genre Magallana (in Anales de la Sociedad Cien- 

 tifica Argentina, Tom. LXIII, pp. 74-81). Magallana porrifolia Cav.
