XVII. POKTULACE^. 



The Portulacece rapidly diminish in number of species with the 

 distance from the sea coast, and thus they appear with much 

 greater abundance in the highland region, where the rocky or 

 sandy soils of Pungo Andongo are much more favourable to these 

 plants, which in general prefer to live under climatic conditions 

 analogous to those of succulent plants; the Purslane (Portulacu 

 oleracea L.) occurs everywhere in the greatest abundance just 

 after the rains ; they not rarely cover extensive pieces of cultivated 

 lands, especially infesting crops' of " Jinguba" (Arachis hypogcea 

 L.). See Welw. Apont. p. 557, and Ficalho, PI. Ut. p. 93 (1884).
