Genera of South African Flowering Plants.

Monimiaceae. 
Xymalos Baill. extends from the Tropics into eastern and north-eastern 
South Africa as far as the Pirie forest near Kingwilliamsto^n. 
Lauraceae. 
The genera Cryptocarya R. Br. and Ocotea Aubl. have a distribution 
paralleled to a certain extent by that of Faurea, there being a more or less 
wide gap in their distribution in the coast districts ; Ocotea extends to the 
Cape Peninsula. Both may be found yet just to reach the Uit. div. in the 
West. The only species of Cassytha recorded extends from the Paarl to 
G-rahamstown. Other species occur much further east. 
HHOEADALES. 
Papaveraceae. 
Palaver L. (introduced?) and Argemone L. (introduced) are each repre- 
sented in the Uit. and P. E. divs, by one species widely spread in South 
Africa. Gorydalis DC. (inch Cysticapnos Adans. [S.W.] ) has several native 
species, of which only one is recorded. Fumaria L. (inch Biscocapnos Ch. 
et Schl. [S.W.] ) is represented in our area by the introduced F. officinalis It. 
The endemic genus Trigonocarpus Schlecht. is only known from the western 
region. 
Capparidaceae. 
The herbaceous South African genera of this order belonging to the 
sub-order Cleomoicleae are absent in the Uit. and P. E. divs. They are only 
found in the eastern, north-eastern, and northern parts of South Africa. 
Gapparis L., Cadaha Forsk, and Maerua Forsk are recorded. None of these 
reach far into the south-west coast region. The genus 5oscm Lam. probably 
occurs on the eastern borders of our districts, but is not recorded. 
Cruciferae. 
Only the genera Brassica L., Sinapis L., HeliopJiila L., Nasturtium 
E. Br., Sisymhrmm L., Lepidium L., Capsella DC. have been recorded from 
the Uit. and P. E. divs., and since, with the exception of Heliophila, these 
are either entirely or partly represented by introduced species, it will be seen 
that our area is very deficient in native species of Cruciferae, a feature which 
is characteristic for the whole of South Africa with the exception of the 
South-West, where the endemic genera, Carponema Sond., Schlechteria Bol., 
CJiamira Thunb., Palmstruchia Sond., Cycloptychis E. Mey., Br achy carp sea 
DC, are found, also Heliophila, which is there enormously developed. 
In our area there are still thirteen species of Heliophila, but the genus thins 
out further east, four species being recorded from ISTatal. Cardamine L. is 
fairly common both east and west of our area. The occurrence of 
Alyssum L., Barharaea E.Br, in the South-West, evidently native, is
