英语语法分析

There is also the Desert Rose (adenium obesium) which looks like nothing so much as a blooming elephant leg.

这里还有沙漠玫瑰（夹竹桃科），把它比作粗壮的大象腿再也合适不过了。

Genus and species in that order are used exclusively when referring to any plant. So instead of "Madagascar Palm" we use Pachypodium lamerei or Adenium obesum in place of "Desert Rose".

属和品种名组成植物的学名，所以，所谓的“马达加斯加棕榈”实际上应当叫做Pachypodium lamerei，而“沙漠玫瑰”则学名Adenium obesum。
