THE PHANEROGAMS OF THE JUAN FERNANDEZ ISLANDS 227 



130. Sonchus oleraceus L. — ■ Johow 1. c. 65. — Masatierra: V. 

 Colonial (no. 167); Pto Ingles; Q. Juanango; B. del Padre (no. 293); Plan del 

 Yunque; Q. de la Choza, wet rock wall in the forest, with other weeds (no. 

 250). — Santa Clara and Morro de los Alelfes. — Masafuera: B. Token; 

 Las Casas; Playa Ancha; Loben'a Vieja. — Johow quotes Moseley as the 

 only collector. J. referred the common Sonchus of the islands to S. fallax 

 Wallr., most likely by a mistake, for it is hardly probable that this has dis- 

 appeared and become replaced by the other. — Also in Chile. 



We learn from this list that the number of weeds is great in the islands, 

 even if some seem to have disappeared and others are scarce. Many play a 

 very important part in the vegetation, such as Anthoxanthum odoratum, Avena 

 barbata, Rumex acetosella, Acaena argentea, Aristotelia maqui, Gnaphalium 

 cheiranthifolium, Amblyopappus pusillus and Silybum Marianum. The western 

 half of Masatierra and Santa Clara are completely stocked with weeds. Also 

 in Masafuera, some species are of great importance, as Avena barbata along 

 the shore and Anthoxanthum and Rumex acetosella in the subalpine and alpine 

 tracts. It is with little enthusiasm that I have had to report numerous species 

 new to the islands. I cannot help putting this in relation to the erection of 

 the penal colony in 1909. The traffic increased, some new weeds were brought 

 to Masatierra and many more to Masafuera. Certainly, this island was abandoned 

 after some years, but the weeds did not leave with the convicts.
