50 THE VOYAGE OF H.M.S. CHALLENGER 



the island in 182S, five years before Bertero's visit. Bertero (1. c.) states, however, 

 that it was common in the vicinity of houses ; but, like many other plants believed to 

 possess medicinal virtues, it was imported from Chili. 



Nicotiana cordifolia, Philippi. 



Nicotiana cordifolia, Philippi in Eot. Zeit., 1856, p. 646. 



Masafueea. — Endemic. Philippi. 



Philippi describes this as a shrubby species allied to Nicotiana solani folia, a Chilian 

 species which we have not seen. 



SCROPHULARINE.E. 



Mimulus parviflorus, Lindl. 



Mimulus parviflorus, Lindl., Eot. Reg., t. 874; DC, Prodr., x. p. 371 ; Gay, Fl. Chil., v. p. 141 ; 

 Philippi in Eot. Zeit., 165G, p. 629. 



Juan Fernandez. — Introduced 1 Philippi. 



A common Chilian species, included in Philippi's list of Juan Fernandez plants without 

 any remarks. 



VERBENACE^E. 



Rhaphithamnus longiflorus, Miers. 



Rhaphithamnus longiflorus, Miers in Trans. Linn. Soc. Lond., xxvii. p. 98. 

 Oitharexylum venustum, Philippi in Eot. Zeit., 1856, p. 646. 



Juan Fernandez. — Endemic. Woods in the hills — Bertero, 1498, in part; Mrs 

 Graham; Scouler; Douglas; Moseleij ; Downton. Masafuera. — Reed. 



Apparently one of the commoner indigenous plants in the island. Mrs Graham notes 

 that it is a large tree ; Douglas says "a small shrub," and Philippi describes it as a small 

 tree. It is, or was called "Arrayan macho" or "espinillo." 



The genus comprises about half a dozen closely allied species, four of which inhabit the 

 mainland of Chili. The following, of which the flowers are unknown, is most likely only 

 a barren state of Rfaxphiihaminus luiujijlorus. 



Rhaphithamnus serratifolius, Miers. 



liltaphithcunntis tcrraf if alius, Miers in Trans. Linn. Soc. Lond., xxvii. p. 99. 



Juan Fernandez. — Endemic. In the higher mountains — Bertero, 1498, in part ; 

 Reed.
