非洲及馬達加斯加的毛氈苔種類


Q: African and Madagascan Drosera species
非洲及馬達加斯加的物種

A: 
Africa is an enormous continent, and contains about 65 carnivorous plant species. Many of these are sundews. Most are occur in southern Africa, but there are a few species that are endemic to tropical Africa. The large island of Madagascar, as troubled as it is by extreme deforestation pressures, adds D. humbertiito the inventory of sundews.

非洲是個巨大的陸地,已知65種食蟲植物分布於此。大部分在此食蟲植物大多是毛氈苔。而且大多分布在南非,但是也有少數種類分布在非洲熱帶區域。而該洲最大的島嶼,馬達加斯加島,目前正受到大量伐林的危機,受害者也包含分布在這D. humbertiit

South African species
South Africa is well known as a land of spectacular botanical diversity. This is partly because it is one of the few places on the Earth blessed with what is called a Mediterranean climate, that is a hot dry summer and a mildly cool, wet winter. Fire is also a vigorous factor that clears vegetation by frequent burns. These factors contribute to a great botanical biodiversity in the South African landscape (actually, there are many other reasons for the biodiversity, including soils etc., but I would be getting off-track if I started in that direction.)

南非產物種

南非算是比較廣為人知具有龐大多生物樣性的地區。這是因為此處地理位置,剛好幸運地處於地中海型氣候,該氣候具有乾熱的夏季及濕涼的冬季。野火也是很重要的因子,
