noteworthy. Several genera, represented by introduced weeds such as. 
Coronopiis Gaertn. (Senebiera Poir.), Rhaphanus L., Diplotaxis DC. are sure 
to be found yet in our area. Arabis L. is recorded from near G-raaff Reinet 
and the mountains of Natal, Turritis L. from the Witbergen, and Matthiola 
E. Br. from the eastern parts of the central region to Burghersdorp and the 
Caledon River. 
Resedaceae 
are absent in the Uit. and P. E. divs. They are only represented in 
South Africa by the genus Oligomeris Cambess., which extends from the 
Transvaal to the eastern parts of the Karroo and from Natal to the Fish 
River Randt. 
Moring-aceae. 
Moringa Juss. occurs in Great Namaqualand. 
SARRACENIALES. 
Droseraceae. 
Brosera L. is found generally distributed in the southern and eastern 
parts, being absent from the drier interior parts. {Boridtila, see under 
Ochnaceae) . 
ROSALES. 
Podostomaceae. 
Tristicha Thouars. has been found in Calvinia div., Kiugwilliamstown 
div., and in Natal (Pietermaritzburg), and Sjjhaerothyl Boschoff in Natal. 
Hydrostachydaceae. 
Hydrostachys Thouars. extends from the Tropics to Natal. 
Crassulaceae. 
Of the nine genera recognised by Harvey in the ' Flora Capensis,' ii, 
p. 328, I keep up only six {Helophytum E. & Z. and BuUiarda DC. being 
sunk in Crassula L. and Bryophyllum Salisb. in Kalanchoe And.). The 
south-western genus Grammanthes DC. is absent in the Uit. and P. E. divs. 
Binacria Harv. extends from the Cape Peninsula through our districts to 
Grahamstown. Bochea DC, also an essentially south-western genus, has 
one species occurring on the Cockscomb Mts., and thus finds its eastern 
limit in our districts. Kalanchoe Adans., which radiates from the Tropics 
into South Africa without, however (except for a short distance near Norval's 
Pont) crossing the Orange River in the North, is represented by two species, 
one of which goes even further west as far as Riversdale. Cotyledon L. has 
a wide distribution all over South Africa. Crassula L., which is also 
universal in South Africa, is largely represented in our area. Several points
