(e) Reamuria types. Chamaephytes which considerably reduce their transpiring 

 surface at the beginning of the dry period (e.g. Reaumuria palaestina, Salsola 



villosa, Siiaeda palaestina, S. asphaltica, Artemisia Herba alba, Zygophyllum 

 dumosum and many others). This group is the most important among the per - 

 manent desert vegetation. Biseasonal annuals (e.g. Salsola autrani) are also 

 included here. 



(f) Launaea type. Annuals, crypto — or hemicryptophytes finishing their life cy- 

 cles at the end of the rainy season. Very abundant.
