Genera of South African Flowering Plants.

having a disjointed distribution, as, in South Africa, it is only known from 
the Calvinia div. Pisoma L. is found in Natal. Boerhaavia Vaill. extends 
to Barkly West, Hopetown and Queenstown. Mirahilis L. is introduced 
in Natal. 
Phytolaccaceae. 
Adenogramma Reichb., Limemn L., Psammotropha, E. & Z., and Phyto- 
lacca L. are represented in the Uit. and P. E. divs. Adenogramma and 
Limeum have fairly general distribution ; the former (endemic) appears to be 
absent from the central region. Psammotropha has mainly western and 
central distribution, but extends to the Drakensberg in Natal. Phytolacca 
penetrates from the Tropics and reaches GraafC Reinet and the Cape 
Peninsula. There remain Microfea Sw. (Kalahari region to Little Nama- 
qualand), Gieselua L. (North and North-east to G-raaff Reinet, also in 
Bushmanland) and Polpoda Presl (endemic, restricted to Cape Peninsula). 
Aizoaceae. 
In the Uit. and P. E. divs. only Orygia Forsk., Hypertelis E. Mey., 
Pharnaceiim L., Tetragonia L., Aizoon L., Galenia L., and Mesembri- 
anthemum L. are represented, the last by a large number of species. East of 
our districts their number is considerably reduced. All these genera are 
fairly generally distributed in] South Africa. Hypertelis (endemic) is 
absent in Natal. Mollugo L. has also fairly general distribution, but does 
not occur on the Cape Peninsula and in the southern coast belt. Glinus L. 
is found in parts adjoining the Tropics and at G-eorge. Sesuvium L. is 
found in the West. The remaining genera are endemic : Anisosiigma Schinz 
(G-reat Namaqualand), Trianthema L. (Western), Plinthus Fenzl (Central), 
Coelanthium E. Mey. (West and South-west), Acrosanthes E. & Z. (South- 
west). (See also Phytolaccaceae.) 
Portulacaceae. 
The genera Talhmm Adans. (East, North, and North-west) and Ceraria 
Pears, et Stephens (Namaqualand) are absent in the Uit. and P. E. divs. 
Anacampseros Sims, like Portulacaria Jacq., a typical Karroo genus, is only 
represented by species belonging to the section Telephiastrum Dill., while 
Portulacaria Jacq. is common in karroid parts of the Uit. div., and mingles 
even with eastern types. 
Basellaceae. 
Boussaingaultia baselloides has become a weed in hedges, etc., in the Uit. 
and P. E. divs., as in many other parts of South Africa. 
Caryophyllaceae.
