Stapelia \Sta*pe"li*a\ (-l[i^]*[.a]), n. [NL. So named after
   John Bodaeus a Stapel, a physician of Amsterdam.] (Bot.)
   An extensive and curious genus of African plants of the
   natural order {Asclepiadaceae} (Milkweed family). They are
   succulent plants without leaves, frequently covered with dark
   tubercles giving them a very grotesque appearance. The odor
   of the blossoms is like that of carrion.
