EUTACE^E. 



Zanthoxylum mayu, Bertero. 



Zanfhoxylum mayu, Bertero in Ann. Sc. Nat, xxi. p. 345, nomen tantum; Hook, et Arn. in Hook. 

 Bot. Miscel., iii. p. 168; Colla in Mem. Accad. Sc. Torino, xxxvii. p. 51, t. 5; Gay, Fl. Chil., 

 i. p. 483; Philippi in Bot. Zeit., 1856, p. 634. 



Juan Fernandez. — Endemic. In the mountain woods — Bertero; without locality — 

 Cuming, 1340; Germain; Reed; Moseley. 



"Arbor procera, vulgo mayu." — Bertero. 



Not strikingly different from the South American species. 



" This is the largest tree in the island, and the present inhabitants call it ' Naranjillo,' 

 and not Mayu, and in the narrative of Lord Anson's voyage it bears the name Myrta. 

 The trunk sometimes attains as much as six feet in diameter, and in Lord Anson's time 

 planks of it thirty feet long were sawn out." — Philippi. 



EHAMNAOE^E. 

 Colletia spartioides, Bertero. 



Colletia spartioides, Bertero in Ann. Sc. Nat., xxi. p. 347, nomen tantum ; Colla in Mem. Accad. Sc. 

 Torino, xxxvii. p. 52, t. 6; Gay, Fl. Chil., ii. p. 34; Hook., Bot. Miscel., iii. p. 173. 



Juan Fernandez.— Endemic. In the higher mountain woods — Bertero. 



This is described by Bertero as a tree six to ten feet high ; it is in none of the later 

 collections at Kew. Colletia is an exclusively South American, chiefly Chilian genus ; but 

 the closely allied, otherwise South American, Discaria, is represented in Australia and 

 New Zealand by one species. Colletia spartioides differs from the other species in its 

 arboreous character.

Jtan Fernandez; Masafuera. Bertero; Reed. 



In the sense here given this species inhabits South America, Easter Island, and New 

 Zealand, being exceedingly common and variable in both regions, and exhibiting the same 

 kind of variation in its most distant habitats. Philippi regards the forms as distinct
