tion of Selago, Eragroslis, Schizoglossum, Earyops, and Zaluzianskya, 

 which are more numerous in the former region. 



The large number of Cycadaceae in the South-Eastern Region 

 should be specially noted, as no member of the Order has yet been 

 recorded from the Eastern Mountain Region, and it is more than 

 probable that they are totally abseut from this region. 



There are in the Eastern Mountain Region 812 species (or 52'31 

 percent.) which also occur in the " Kaffrarian " flora, though of this 

 number 317 species (or 2O4 per cent.) are common to the Kalahari 

 Region, the Eastern Mountain Region, and the " Kaffrarian " 

 Region. 



VIII. SUMMARY. 



The Eastern Mountain Region is a large plateau lying between the 

 28th and 30th degree of latitude and the 27th and 30th degree of 

 longitude. It includes the whole of Basutoland with a portion of the 

 Orange Free State, the. Cape Province, East G-riqualand, and Natal. 

 On the confines of its boundaries it has an elevation of about 5000 ft., 

 rising to 10,000 ft. and over on the Drakensbergen. The area is built 

 up of Stormberg beds which lie on the Karroo beds. The rainfall 

 averages about 29'39 inches per annum, most of which falls during 

 the six summer months. The average maximum temperature is about 

 82 F., and the average minimum temperature about 33 F. In the 

 greater amount of rainfall and lesser extremes of temperature the 

 Eastern Mountain Region shows considerable differences from the 

 Kalahari Region. The Eastern Mountain Region must be regarded 

 as a grass steppe, and in this respect differs somewhat from the 

 Kalahari and South-Eastern Regions, where the Grasses do not form 

 such a predominant portion of the flora. The paucity of species 

 of Capparideae, Ampelidaceae, Asclepiadaceae, Convnlwidaceae, etc., 

 separates it from the Kalahari Region, and the few species of 

 Acanthaceae, Celastraceae, Oleaceae, Rutaceae, etc., which occur within 

 its limits distinguish it from the South-Eastern Region. Among 

 the genera the number of species of Erica, Zaluzianskya, Wahlen- 

 bergia, Enlopliia, Disa, etc., which occur in the Eastern Mountain 

 Region sharply separate it from the Kalahari Region, while the 

 number of species of Selago, Eragrostis, Schizoglossum, Enryops, 

 and Zaluzianskya distinguish it from the South-Easteru Region. 

 Speaking generally the Eastern Mountain Region has an affinity with 

 the South-Eastern Region, but is totally distinct from the Kalahari 

 Region.
