Genera of South African Floivering Plants. 
39 
Cyclopia Yent., Priestleya DC, Borbonia L., and Virgilia Lam. have their 
eastern limits in our districts. Podalyria Lam. extends to Natal ; Amphi- 
thalia Thunb. extends to Cathcart ; Rafnia E. and Z., and Leheckia Thunb, 
extend beyond G-rahamstown ; Hallia Thunb. extends to the neighbourhood 
of G-rahamstown. 
The genus Dumasia DC. is not recorded, although it occurs both east and 
west — namely, at the Knysna and in the Pirie forest near Kingwilliamstown, 
in Natal and beyond. 
GERANIAALES. 
Geraniaceae. 
The genus Sarcocaulori DC. with central, western, and north-western dis- 
tribution is absent in the Uit. and P. E. divs., although it extends into the 
Fish Eiver valley. Erodium L'Her is introduced. Monsonia L., which is 
scattered over the greater part of South Africa, is represented by one species. 
Of Geranium L., represented by only few species in the southern coast dis- 
tricts, three species are recorded. The large number of recorded species of 
Pelargonium L'Her. is only to be expected, as our districts form, in a sense, 
the centre of the distribution of the genus. The section Hoarea DC. does 
not extend east of the Uit. and P. E. divs. A useful summary of the dis- 
tribution of the sections of the genus is given by E. Knuth in 'Pfianzenreich,' 
iv, 129, p. 37. 
Oxalidaceae. 
Oxalis L., the only genus represented in South Africa, is found in the 
coast districts of South Africa, with its headquarters in the south-western 
region. Towards the East the number of species diminish. Few species 
penetrate towards the interior. 
Linaceae. 
Linum L. is the only genus represented in South Africa. It is widely 
spread in the southern coast districts, going far inland in the eastern parts. 
Erythroxylaceae. 
Erythroxylon P. Browne extends from the Tropics to the eastern and 
north-eastern parts, and along the east coast to East London. 
Zygophyllaceae. 
Tribulus Tourn. is very widely spread in South Africa. Zygojohyllum L. 
is absent from the eastern parts (my most eastern records are Port Alfred, 
Fort Brown, Burghers dorp), otherwise it is widely spread with its head- 
quarters in the Karroo. All other South African genera are unrecorded in 
the Uit. and P. E. divs., namely, Neoluederitzia Schinz (Namaqualand), 
Seetzenia E. Br. (western), Fagoyiia Tourn. (western), Sisyndite E. Mey.
