Southern Islands is a set in the Other series. It was released on July 31, 2001. The printed size is 18, and the checklist is the same length. Vileplume is 17/18, in position 17 of 18 on this checklist. Before it is 16 Lickitung, and after it is 18 Primeape.
Vileplume is a Stage 2 Grass Pokémon with 70 HP. In the Pokédex this is Vileplume (#045), generation 1 (Kanto). The card says it evolves from Gloom. In this catalog that name is Gloom (#044).
Naoyo Kimura illustrated this card. The same name is on 256 other cards in the catalog.
Vileplume (#045) has 25 other cards in the catalog. Those other cards are in 19 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Vileplume 15/64 in Jungle (1999). That card lists 80 HP, and this one lists 70 HP. Keiji Kinebuchi illustrated that card, and Naoyo Kimura illustrated this one. 25 other cards of Vileplume list a different HP.
The attack Paradise Pollen lists no damage number. The cost is Grass. Flip a coin. If heads, remove 2 damage counters from Vileplume (1 if it only has 1). Then, if you have any Benched Pokémon with damage counters on them, choose 1 of them and remove 2 damage counters from it (1 if it only has 1). Horrid Pollen is another attack lists 30 damage. The cost is Grass, Grass, Colorless. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. If tails, the Defending Pokémon is now Confused. Weakness is Fire ×2. Retreat cost is 2. The flavor text reads "This Pokémon makes a loud jangling noise when it shakes its petals to spread poison powder."
I keep a set binder for Southern Islands, meant to hold every card of that set. This card is one slot in the Southern Islands set binder. A generation binder holds one card of each species. Vileplume can fill a slot in Generation 1 binder (Kanto). I still need this card.
