P. 544 : 



This genus is not named in the list of Tropaolacece 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-

 distinct from the genus Tropceolum is further established. Nevertheless 

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

 synonymous with Tropceolum. 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.
