Origin of the Angiospermous Flora of South Africa. 339 



Crotalaria, with 250 species ; distributed over the Tropical and 

 sub-Tropical countries of both hemispheres. 



1 genus in the Southern Andine Eegions ; 1 monotypic genus in 

 South-East Brazil ; 1 monotypic genus in India and Ceylon ; 

 1 genus in the Eastern Himalayas and Socotra. 



Gkubbiace^. 

 Hieronymus (in Engler-Prantl, Natiirl. Pflanzen-fam., iii., 1, p. 229) 

 expresses the opinion that this order represents the prototype of 

 SantalacecB. It has 1 genus with 3 species in South-West Cape 

 Colony. 



Santalace^ 

 (after Hieronymus in Engler-Prantl, Natiirl. Pflanzen-fam.) 



This order has 4 main centres of development : (1) South Africa, 

 with the largest number of species ; (2) Australia ; (3) South 

 America ; (4) South Asia and the islands of the Malay Archipelago.''' 



I. AnthobolecE. 



1 genus in Australia, New Zealand, the Malay Archipelago, and the 

 Sandwich Islands ; 1 in Malakka and the Malay Archipelago. 



II. OsyridecB. 



4 genera in Australia (1 also in New Zealand), 1 in Burmah and 

 Malakka, 1 in East India, China, and the Malay Archipelago, 1 in 

 East India, 1 {Colpoon) in South Africa, 1 in the southern part 

 of South America and the Falkland Islands, 1 in Chile, 1 (Osyris) 

 in South Europe, almost the whole of Africa (including South 

 Africa) and East India, 1 in Japan and North America, 1 in East 

 India, the Malay Archipelago, the Pacific Islands, and Australia, 3 in 

 South America, 1 along the Lower Danube and in North America, 



1 in North America and the Himalayas. 



III. Thesiem. 



2 genera in South Africa {Osyridocarpus and Thesidium), 1 genus 

 {Thesium) in the temperate regions of the Old World, but also 

 sparingly in the Tropics (strongly represented in South-West Cape 

 Colony), 2 in Chile, the Argentines, and Patagonia. 



I think amongst these facts of distribution there are a good many 

 which support the view of Hooker's that many of our South African 



* The Myzodendracece, a reduced type of Santalacece, are only found in South 

 Chile and near the Straits of Magellan.
