 pachychlamys, Eucomis undulata, Scilla rigidifolia 

 var. nervosa, S . natalensis, Ornitliogalum zeyheri 

 and other bulbous niouocotyledons. Many ot these, however^ 

 e. g. species of Mora?a and Aristea, prefer the uioister spots 

 and are included in the list of those transitional to the vleis. 



The Com]^osita3 hold the chief place in this class^ 

 especially amongst those flowering in autumn. The bulbous- 

 Monocotyledons are also very abundant, their growth-forms 

 being well adapted to the habitat. Hemi-pai-asitic Scrophu- 

 lariacete belonging to the genera Cycnium, Harveya, and 

 Striga are common, their mode of nutrition making it 

 necessary for them to grow intermingled with the grasses, 

 which are their hosts. 



(B) Associated Veld Plants occupying bare patches and- 



ROCKY GROUND. 



These are transitional to rocky scrub and also to the 

 talus-slopes, marginal to scrub and bush. The various species^ 

 may grow gregariously or may be individually somewhat 

 rare.
