Genera of South African Flowering Plant.

Presl), Cyphia Berg., Wahlenbergia Schrad. and Lightfootia L'Her. are 
common in the coastal belt from Clanwilliam to Natal and in the eastern 
mountains, but are poorly represented in the Karroo and the Kalahari 
region proper. Laurentia Neck. (incl. Enchysia Presl.) is chiefly found in 
the South-West, but one species occurs near Grrahamstown and one still 
further east. Prismatocarpus L'Her. (endemic) is essentially south-western, 
but extends to G-rahamstown. Boella L. (endemic), also mostly south- 
western, occurs as far as the Uit. div. and then again from East Loudon to 
Natal. The following south-western genera (all endemic) do not reach the 
Uit. and P. E. divs. : Microcodon A. DC, Sipliocodon Turcz, Bhigiophyllum 
Hochst., Merciera A. DC. and Treichelia Vatke {Leptocodon Sond.). 
Gephalo stigma A. D.C. enters temperate South Africa in the extreme North- 
West, Sphenoclea Graertn. in the North East. 
Goodeniaceae. 
The only South African genus, Scaevola L., represented by a single 
species inhabiting the sand on the seashore, is recorded from the Uit. and 
P. E. divs. and extends both East and West, in the latter direction as far as 
Mossel Bay. 
Compositae. 
The enormous number of South African genera of Compositae can be ar- 
ranged in several groups more or less well defined as regards their distribution. 
1. Over 40 genera with more or less general distribution (some restricted 
to the southern coast districts and some not reaching to the Cape Peninsula). 
Of these Dicrocephala DC. and Chrysanthemum. L. are not found in the Uit. 
and P. E. divs. 
2. About 20 genera, radiating from the Transvaal and Natal chiefly along 
the southern coast districts. Most of these do not come near our districts. 
Tanacetum L. stops at Bedford and East London, Schistostephium L. in the 
Albany district. Artemisia which extends to Oenadendal, is not recorded. 
Vernonia Schreb. and Stephanocoma Less, extend much further west, 
while Mihania, Willd. has its western limit at Van Stadens and Launea 
Cass. (Microrhynchus Less.) at Coega. 
3. Over 40 genera are mainly found in the south-west coast region, some 
with very local distribution. Of these about 28 do not reach our districts. 
Oedera L. and Landtia L. are not recorded though occurring further east, 
namely near Grrahamstown. Amongst the recorded ones Corymhium L. 
Bisparago Graertn., Helipterum DC, Oldenburg ia, Less., reach the neighbour 
hood of Grahamstown. Elytropappus DC, though common near Grrahams- 
town, is introduced, and probably also reached the Uitenhage district through 
the agency of man ; Heterolepis Cass., CuUumia, P. Br., have their eastern 
limits in our districts, Gorteria, L. at Hankey.
