Genera of South African Flowering Plants. 
47- 
Struthiola L. (endemic) in the South-west extending to the Ceres div. and 
along the southern coast belt to the Albany div. and appearing further in 
East Pondoland. Dais L. is found in the North-east and East southwards to 
Kingwilliamstown (outside South Africa it only occurs in Madagascar). 
Englerodaphne Grilg. is recorded from East London to Natal, Synaptolepis 
Oliv. from Delago Bay, Peddiea Harv. from the North-east and East (extends 
to Komgha). 
Lythraceae. 
This order radiates from tropical Africa into South Africa. Of the six 
South African genera only Lythrtim L. gets anywhere near to the south- 
west coast region, and this ""only by a widely spread species which is 
recorded from the Uit. and P. E. divs. 
Rhizophoraceae. 
Bhizophora L. and Brugiiiera Lam. occur on the coast from the Transkei 
northwards ; Weiliea Spreng. in the coastwards forests of the East, extend- 
ing to the Amatolas near Kingwilliamstown ; Cassipo2crea Aubl. in East 
Pondoland and Natal, 
Combretaceae. 
Only Comhretum L. reaches our districts from the East in one species 
which does not seem to extend beyond Van Stadens. Quisqualis L. and 
Terminalia L. skirt the Tropics, but do not reach Natal. 
Myrtaceae. 
Two species of JEtigenia L. are recorded from the Uit. and P.E. divs. 
This genus does not seem to occur west of Van Stadens. Metrosideros 
E. Br. (south-western), Sizygium Gaertn., and Heteropyxis Harv. (both 
eastern) are absent. 
Melastomaceae. 
This order penetrates from the Tropics : Memecylon L. to Natal, Dissotis 
Benth. (incl. Argyrella Naud.) and Osbeckia L. to East Pondoland. 
Oenotheraceae. 
Only the genera Oenothera Spach. and Epilohium L. are recorded from 
the Uit. and P.E. divs. The former is introduced. The remaining three 
South African genera are eastern and are found in Natal and beyond, only 
Ludwigia L. comes as close as Kingwilliamstown. (Montinia, see under 
Saxifragaceae.) 
Halorrhagidaceae. 
Gunnera L., Lauremhergia Berg. (Serpicula L.), and Myriophyllum L, 
are recorded from the Uit. and P.E. divs. The last does not seem to occur
