TrVAMA (who divided my section Eusanialum in 2 and referred the Hawaiian 

 tLusantala to a sejxirate section SolenaJithus), Fjisantalinu s. str. is the largest with 9 

 species, SoloiaJithus and sect, llawaiiensia (together 8) confined to Hawaii (incl. Lay- 

 san), and sect. Poly)icsica (2, with varieties) to Polynesia; in this section the extinct 

 .V. fi-riiajideziajnofi occupies a rather independent position. "Aber woher kam der 

 frenulartige l'>eniit Santaluni.-" lU'RC.KR [4.1. 22) exclaims, "zweifelsohne fern aus 

 ostindischen Meercn, wo die W'iege seines altberiihmten Geschlechtes steht" — 

 nothing could give a wronger idea of the history of the sandalwoods, because 

 everything points toward Antarctica as their cradle. There are related endemic 

 genera in Australia, Mida in New Zealand, Jixocarpus ranges from Australia across 

 Polynesia to Hawaii, and several endemic genera are at home in temperate S. 

 America [Arjojia, lodiiia, Ouidia, QuincJianialiuui, and Xa7iodea in the extreme 

 south and in the Falkland Is.); one is tempted to regard the family as of Antarctic 

 ancestry, but with Thesiiini in mind it might be safer to speak of a special 

 Antarcto-tertiary centre. 



The 3 endemic species of CheJiopodiuin were commented upon above (p. 204). 

 In general appearance they are very like the Hawaiian oahuense but the special- 

 ist oj)ines that they are not nearly related to this nor to other species, I can find 

 no better place for them than in a neotropical group. 



SalicoDiia fruticosa, taken in a wide sense, is a thalassochorous plant scattered 

 along tropical and subtropical coasts; the same is the case with Tetragoiiia ex- 

 pausa in the S. hemisphere, but while Saliconiia is a world-wide genus, Tetra- 

 i:;o)iia has a stronghold in South Africa and several endemic species in Chile. 



Sptrj^idar/a is a wide-ranging, but mainly boreal genus with a vigorous branch 

 in Andean America but absent from Australia, New Zealand and Oceania. The 

 2 island species, of which .V. co7ifertiJiora is also found on San Ambrosio, are 

 closely related to Chilean species. Paronychia has about the same distribution 

 j)attcrn as Spcyo^ularia, but is poorly represented in S. America. 



RamDuulus capraniui. A very large essentially boreal-temperate genus with 

 Avell stocked branches in S. America and on New Zealand. The Masafueran en- 

 demic stands a|)art from its American congeners and approaches certain New Zea- 

 land sj)ecies, j)crhaps also the Hawaiian ones. An Antarctic migration route seems 

 probable. 



Fuyheris coryinbosa and niasafuerana belong to a small section confined to 

 the tropical Andes and not extending to Chile, where we have many other spe- 

 cies. The present area of the Berberidaceae testifies to its Arcto-tertiary charac- 

 ter; it centres in \\. and S. Asia and ranges far south only in America, where 3 

 species reach I'\iegia. 



Of the six genera of W'interaceae (<\?), Bubbia has 2 species in Australia, 

 I on Lord Howe I., <S in New Caledonia and 19 in New Guinea, Belliohun 4 

 in New Caledonia and 4 in the Solomon Is., Pseudowintcra 2 in New Zealand, 

 Jixospoimiin 2 and Zy^^^ogyjiu))! 6 in New Caledonia, and Drimys 6 in Australia 

 {i also in Tasmania), 29 in New (Guinea and i on Borneo, Celebes and in the 

 Philippines, all these belonging to sect. Tasma7iia\ the other section, Eudrimys, 

 is American with 4 species, J), confcrtifolia endemic in Juan Fernandez. This sec-
