54 THE VOYAGE OF H.M.S. CHALLENGER. 



SANTALACEzE. 



Santalum. 

 Juan Fernandez. 



Sandalwood of some kind formerly abounded in the island, as we learn from the 

 narratives of the early voyagers, and from the dead trunks of the tree existing as recently 

 as 1856. Gay names the Juan Fernandez sandalwood Santalum album, without doubt, 

 but it seems very uncertain whether it belongs to this genus even ; for, although it is 

 Polynesian (including the Sandwich Islands), it is not represented in America. See para- 

 graph thereon in the introductory notes to this part, p. 11. 



LORANTHACE^E. 

 Loranthus berteroi, Hook, et Arn. 



Loranthus berteroi, Hook, et Arn. in Hook. Bot. Misc. (1833), iii. p. 357 ; Walp., Repert. Bot. 



Syst., ii. p. 445. 

 Loranthus venetus, Bert. MSS., non H. B. K. 

 Loranthus tetrandrus, Philippi in Bot. Zeit., 1856, p. 628, non Ruiz et Pavon. 



Juan Fernandez. — Endemic. Parasitic on Myrtus femandeziana — Bertero. 



We have only seen Bertero's specimen, which is a good one, and evidently distinct 

 from Loranthus tetrovphyllus. Of course the latter may also occur in the island; yet as 

 Philippi has only one species, there is some justification for assuming that it is Loranthus 

 berteroi. 



EUPHORBIACE^E. 



Dysopsis gayana, Baill. 



Dysqpsis gayana, Baill., Etude General des EuphorLiacfes, p. 436. 



Molina chilensis, Gay, Fl. Chil., v. p. 346, et Atl., t. 62. 



Mirabellia glechomoides, Bertero MSS. cited in Steudel's Nornenel. Bot., and also l>y Baillon. 



Bowlesia crenata, Desv. ex DC, Prodr., iv. p. 70. 



Ilijih-oeolijle ijlfi-liomoiihs, Rich., Monogr. Hydroeot., n. 14, t. 58, fig. 17. 



Dysqpsis glechomoides, « hirsuta, Midi., Arg. in DC. Prodr., xv. 1, p. 949. 



J dan Fernandez. — Humid shady places in the mountain woods — Bertero; Reed; 

 Moseley. 



In Ecuador, and very common in Valdivia and Chiloe ; also in Fuegia. 



M nller (1. c.) defines two other varieties; the insular form differing from them mainly 

 in being clothed with longer hairs.
