Juan Fernandez ; JMasafuera. — Common, and in all collections from Bertero's time 

 to the present. 



Widely spread in temperate regions, both north and south, though perhaps originally 

 introduced into the southern hemisphere. Eohrbach designates the Juan Fernandez plant 

 as " Species ab omnibus seminum testa structura distinctissima. Tuberculi enim omnibus 

 ceteris speciebus semper sunt multo longiores quani latiores, forma cylindrica, ad apiceni 

 versus dilatata. ... In nostra autem specie tuberculi sunt bundles, sed ad axin unam 

 valde dilatate, quasi vermifonnes et sa^pe paullum curvati."

Juan Fernandez, ex Philippi. 



Not uncommon in the central and southern provinces of Chili, whence it may have 

 been introduced into the island. An annual herb, in none of the Juan Fernandez collec- 

 tions consulted. The only species of the genus.

Juan Fernandez. Germain ; Rod ; Moseley. 



One of the commonest and most widely spread species in Chili. The insular form is a 

 small one, with smaller flowers than the ordinary continental one.
