400 NATURAL HISTORY OF PLANTS. 
time he inserted the genera Awaz of Buretus,' Mimetes, Serruria, and 
Spatalla of Satispury,? Adenanthos and Cenarrhenes of LABILLARDIERE,’ 
Conospermum, Xylomelum, Persoonia, and Lambertia of Smita,‘ Hakea of 
Scuraver, Helicia and Cylindria of Lourgtro.’ Thus were collected, 
besides Protea, thirty-seven of the genera now retained. ‘The eight 
others are of far more recent date. Scuorr founded Andripetalum.* 
Mutssner added Molloya in 1855,’ and in 1856 Potameta of Durgtit- 
Tuovars ;° Harvey added the Cape genus Fawrea in 1847,” and F. 
Moe ter” the four Australian genera, Cardwellia, Darlingia, Carnar- 
vonia, and Buckinghamia. Finally, we have recently demonstrated” 
that Potameia really belongs to Lauracee, but that another ill-known 
genus of Dupetit-Tuovars, Dilodeia, 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, Maurea, 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 ovuleis ascending and anatropous in all but Bradejum 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 Lmbothrium, Guevina, Roupala, 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 Proteacee, containing representatives of four or five genera.
