Note on the South African Proteacece. 
277 
dociwpodendron, Conocarpodendron, Siud Hypo2)hyllocarpodendr on, composed 
follows : — 
Lepidocarpodendron contains 10 species of Protea, 1 species of 
Aulax (?), 1 species of Mimetes. 
Conocarpode7idron contains 7 species of Leucadendron, 1 species of 
Protea, 1 species of Leucospermum. 
Hypophyllocarpodendron contains 2 species of Mimetes. 
It will be important to bear in mind the composition of Boerhaave's 
genera when dealing with the works of Linnaeus. The first collection of 
coloured plates of Proteacese appeared in 1745, by Weinmann,"^' who only 
recognised one genus, which he called Scolymocephalus, and in which he 
included species of Protea, Leucospermum, and Leucadendron. Between the 
years 1735 and 1774 appeared the various works of Linnaeus, important as 
introducing the binomial system of nomenclature, but also important from 
•our point of view, as he deals with the Proteaceae in his Class Tetrangia 
Monogynia, and was the first author to use the name Protea. That 
LinnaBUS could not come to a definite conclusion as to the limits of the 
two genera Protea and Leucadendron is clearly evidenced in his works if 
his descriptions and references to Boerhaave's figures are compared, and 
it may not be out of place to state his views in their chronological order 
so far as I have been able to determine them. 
For the sake of brevity we will denote the genera as follows : — 
Conocarpodendron = K. 
Hypophyllocarpodendron = B. 
Lepidocarpodendron = C. 
1. 1735 Syst. Veg. Protea = A, B, C. 
2. 1735 Hortus Chffortianus Protea^ A, B, C. 
3. 1737 Genera Plantarum Protea = B, C, not A. 
4. 1738 Classes Plantarum Protea = C 
Leucadendro7i = A. 
5. 1742 Gen. PI. Protea = A (partly). 
Leucadendron — A (partly), B, C.
