400 NATURAL HISTORY OF PLANTS. 



time lie inserted the genera Aulax of Bergius, 1 Mimetes, Serruria, and 

 Spatalla of Salisbury, 2 Adenanthos and Cenarrhenes of Labillardiere/ 

 Conospermum, Xylomelum, Persoonia, and Lambertia of Smith/ Hahea of 

 Schrader, Helicia and Cylindria of Loureiro. 5 Thus were collected, 

 besides Protea, thirty-seven of the genera now retained. The eight 

 others are of far more recent date. Schott founded Andripetalum* 

 Meissner added Molloya in 1855/ and in 1856 Potameia of Dupetit- 

 Thouars; 8 Harvey added the Cape genus Faurea in 1847/ and F. 

 Mueller 10 the four Australian genera, Cardivellia, Barlingia, Carnar- 

 vonia, and Buckinghamia. Finally, we have recently demonstrated" 

 that Potameia really belongs to Lauracea, but that another ill-known 

 genus of Dupetit-Thouars, Dilobeia, should be placed not far from 

 Aulax. Thus we retain forty-six genera in this Order. 



These forty-six genera contain some 1000 species. Of this number, 

 270 are peculiar to South Africa, and 87 to South America and the 

 Antilles. Only one Mexican species is known ; and all the rest, 

 comprising about 650 species, are peculiar to Oceania, especially 

 Australia and South Asia. There are eleven African genera, of which 

 Dilobeia alone is peculiar to Madagascar. The others are four for 

 each, Faurea, Brabejum, Protea, Leucospermum, Mimetes, Aulax, Leu- 

 cadendron, Nivenia, Sorocephalus, Serruria, Spatalla, nearly all be- 

 longing to the Cape of Good Hope and the neighbouring parts. One 

 Protea and one Leucospermum are alone found in Abyssinia. We 

 may remark that all these plants have a uniovulate ovary, and that 

 the ovule is ascending and anatropous in all but Brabejum and Faurea. 

 South-eastern Asia contains the single genus Helicia, also occurring 

 in Australia and the Indian Archipelago. In America are found 

 the five genera Embothrium, Guevina, Boupala, Lomatia, and Andri- 

 petalum ; the two last occurring in Oceania also. All the other 

 genera are peculiar to that quarter of the globe, especially Australia, 

 Tasmania, and New Zealand. New Caledonia appears equally rich 

 in Proteacea, containing representatives of four or five genera.
