some were published in Barreiro’s earlier incomplete edition, 
they may be considered as nomina nuda. Amongst the names 
used in the Relacidn, a few are synonyms; it has been possible in 
some cases to indicate in brackets under the original binomial the 
currently accepted name. 
The genera are arranged alphabetically under families. The 
families are enumerated in accord with the system of Engler and 
Prantl. 
POLY PODIACEAE 
Polypodium Incapcocam nom. nud. 
(cucacuca; incapcocam; coca del Inca) 
According to the Indians, the Incas used the leaf in place of real 
coca. In the form of a powder, it was taken instead of tobacco “to 
clear the head.” 
PTERIDACEAE 
Achrostichum Cuacsaro Bert. Opusc. Sci. Bol. 1 (1817) 241, t.8. 
(cuacsaro) 
The roots are sold commercially as genuine calaguala (Polypo- 
dium sp.), but they lack the medicinal virtues. 
ARAUCARIACEAE 
Pinus chilensis nom. nud. 
[Araucaria araucana (Mcl.) C. Koch Dendrol. 2, 11 (1873) 206. | 
(pino de Chile) 
When the natives engaged in felling this tree gash themselves 
severely, they apply the resin of the tree to the wound. “There is 
no doubt that it produces the effect that they want. It is also 
found to be very helpful as a calmative in cases of ruptures and 
bruises.” 
ARACEAE 
Calla nuda nom. nud. 
The root is thought to have properties making it effective in the 
treatment of snake bites. 
BROMELIACEAE 
Pourretia coarctata R. et P. Fl. Peruv. 3 (1802) 34. 
[Puya chilensis Mol. Sagg. Chil. (1782) 160, 351.] 
(card6n; puya)
