XLVIII. DROSERACEiE. 



The Droseracese of Angola are essentially highland plants. 

 Even in the hilly region, where a moist atmosphere and spongy 

 ground are certainly not rare, Welwitsch did not find a single 

 species, and it was only about 15° S. lat. at an elevation of 5000 

 to 6000 ft. that several species were met with. Lrosera indica L, 

 descends lowest, namely to 3200 ft., but the geographical distri-
