definite associes with StenotapJirum glahrum or consocies by 

 itself between the Psammophilous Bush and the sea, or on 

 sandy flats near the shore. It is a prostrate species, which 

 roots from the proliferously branched nodes, and is sometimes 

 used for making hiwns. 



Uantlionia is another temperate genus chiefly character- 

 istic of the South Western region of Macchia, though a few 

 species have a more eastern distribution. At the Cape the 

 principal species are D. macrantJia, D. lanata, D. lupuJina, 

 D. elephdutinu, 1). cincta, IJ. stricta, and D. ctirra, all very 

 xerophytic, hard leaved, deep rooted species, which grow 

 among the Macchia shrubs. In cross section their leaves are 

 somewhat similar to those of Achneria and Peiitaacliistis or 

 those of r>. distich a (see Fig. 8 below). Some of the species

are only recorded for IS^amaqualaud and the West, e.g., D. 

 dura, U. piimila, D. tenella, D. glauca, D. rangei. The most 

 interesting, however, are the species which extend Eastward 

 along the mountain ranges and the coast. D. inermis occurs 

 at Port Elizabeth, D. decuinhens in the Amatolas, D. cincta 

 on the mountains around Grahamstown, I), suffrutescen.^ 

 around Prieska and Carnarvon districts, and Z>. stricta on the 

 Drakensberg. D. macmrnni , or a species very near it, I have 

 gathered in the upper reaches of the Tugela on the Natal side 

 of the Drakensberg. 



D. disticha is common on the Stormberg, and mountalu.s 

 around the Karroo. It grows usually among rocks, and is a
