THE PHANEROGAMS OF THE JUAN FERNANDEZ ISLANDS 121 



one large specimen in the gorge among rocks (no. 523). The species is every- 

 where persecuted by the indefatigable goats. 



Differs from the other species in the much greater size, the shape of the 

 leaves and fruit, etc. Seeds from no. 550 were sown in the Gothenburg Garden 

 in 1918, the plants are quite typical, but have not yet produced flowers. Their 

 habit is truly arborescent. 



Area of distribution: Endemic in Masafuera. 



The three Juan Fernandez species of Chenopodium, each confined to a 

 single island, are related to Ch. paniculatum Hook, from North America, Peal 

 and Chile, ranging from 49 N. to 32 S. This is a polymorphic species that 

 was treated by J. MuRR in Oesterr. Bot. Zeitschr., it is herbaceous or »halb- 

 strauchartigs and the leaves mostly entire. The island species are probably 

 also related to Ch. sandwicheum Moq. from Hawaii.
