From the Super Mario Wiki
A Volcano Lotus is a plant that shoots out fireballs in Super Mario World and Super Princess Peach. They appear in many levels, spewing small fireballs into the air at a diagonal angle, which proceed to slowly rain down on the surrounding area after reaching their highest point. To defeat them, they must be hit by whirling Mario's cape next to them or eaten by a Yoshi. Spin jumping on them or stepping on them while riding a Yoshi will not harm them, but will make the player bounce off without taking damage. The Volcano Lotus might be related to a similar enemy found in Super Mario Bros. 3, the Lava Lotus, although the latter is only found underwater.
In Super Princess Peach, they are referred to as Volcano Plants. The game also introduces a "Calm" sub-species, the C. V. Plant.
A Volcano Lotus, referred to as a fire plant, appears in the episode "Send in the Clown" of the Super Mario World television series. It produces the fireballs that Mario, Luigi, Yoshi and Princess Toadstool use in a tennis game (in lieu of actual tennis balls).
They share the same Japanese name as Panser, meaning that they may be intended to be the same or a related species, although they look and act differently.
