squarrosum is similar. Pollinia villosa is commonest in Coast 

 Veld, and the other genera of the tribe Andropogoneae belong 

 to the hvdrosere. 



The Paniceae are very poorly represented in the climax 

 Grassveld, the majority of them being ruderal or belonging to 

 the forest sere, but a few are of importance. The large genus 

 Panicum is represented by P. serration and P. natalense. 

 Digitaria monodactyla, 1). eriantha, I), setifolia, D. diago- 

 natis, D. tricJiolaenoides all enter more or less into Grassveld. 

 Axonopus semialatus var. eoklonii is common in early spring 

 and forms small societies. The Tricholaenas belong to the 

 early stages, and Setaria perennis is the only common Veld 

 species of Setaria, the rest belonging to the hydrosere. 



Trichopteryx simplex is common and forms clans; the 

 other species 2. flavida and T. dregeana are not so common. 

 Tristachya leucoihrix forms vernal aspect societies. T. 

 rehmanni is a Transvaal species fairly common in the High 

 Veld. The great tribe of the Aveneae are hardly represented, 

 though so abundant in the South Western region . Koeleria 

 cristata and Avenastrum turgidulum occur, but are rather to 

 be reckoned as Mountain Veld species. 



Among the Eragrosteae, the two species Eragrustis 

 gummiflua and Pogonarthria falcata form an association, 

 which is characteristic of the dolomite soils of the Transvaal. 

 Both species occur more sparsely elsewhere. The majority 

 of the species of Eragrostis are found in the initial stages, 

 but some occur in the climax grassland, e.g., E. brizoides, 

 E. superba, E. lappula, E. caesia, E. denudata. Chloris 

 virgata is the only species of this genus which occurs in climax 

 grassveld. The others are either ruderal or belong to the 

 initial stages. All are reckoned very nutritious grasses. 

 Harpechloa capensis is not common except at the higher 

 altitudes. Cteniwm continuum is locally abundant (in Pondo- 

 land). The Festueeae and other smaller tribes are hardly 

 represented except in Mountain Veld. 



From the floristic standpoint, the almost complete absence 

 of the temperate tribes Aveneae, Phalarideae, Festueeae, 

 which include all the important Cape genera, is worthy of 

 note.
