In the wet sand and growing subsocially are C^perus rupestris^ 

 and Crassula laxa while in the water are Crassula natanSt. 

 Crassula parvula and Lobelia (Metzlena dregeana). Aj 

 evidenced by many of the dry pans examined the above must 

 be regarded as a stage in the plant succession which forms a bed 

 on to which the grasses first migrate followed by such species as 

 Metalasia muricata and Indigofera melanadenia. 



The bulk of the species found in the localities described above 

 are plants with underground resting winter buds. The leaves are 

 simple, sessile, broad, entire and glabrous; the flowers medium in 

 size and of a yellow colour; the fruits capsular. This statement 

 is based on a detailed examination of the various organs. 



If we exclude the glumaceous monocotyledons we find that 

 71*8 per cent, of the species have sessile leaves and 28* 1 per 

 cent, have petioled leaves. Simple leaves are represented by 

 76* 3 per cent, of the species and compound leaves by 23* 6 per 

 cent. The difference between glabrous and hairy leaves is not so 

 great- — 59* per cent, glabrous and 41*0 per cent, hairy. The 

 latter is made up as follows: — Pubescent leaves 20* 9 per cent., 

 woolly leaves 10-9 per cent., tomentose leaves 7*2 per cent, 

 hispid leaves 1 • 8 per cent. Incisions (incised, crenate, dentate, 

 serrate, etc.) on the margins of the simple leaves (or the leaflets 

 of compound leaves) are uncommon and are only met with in 

 11*8 per cent, of the species while 88 • 1 per cent, of the 

 species have entire leaves. Most of the species have broad leaves 

 (50 per cent.), linear leaves are met with in 42: 7 per cent, of 

 the species while ericoid leaves are rare (7:2 per cent.). 



In comparing the size of the flowers one can only make re- 

 lative comparisons. Species Avith conspicuous flowers or flowers 

 massed in a conspicuous inflorescence comprise 28* 1 per cent, 

 of the total number of species; rnedium-sized flowers are found in 

 4A ' 5 per cent, of the species and small or inconspicuous flowers 

 in 27-2 per cent, of the species. The predominant colour of 

 the flowers is j^ellow (43* 6 per cent). Other colours represented 

 are white (20* per cent.), red (12- 7 per cent.), blue (10* 9 

 per cent.), green (9-0 per cent.), purple (2*7 per cent.), and 

 brown (0-9 per cent.).
