Cherrim is Pokédex #421, generation 4 (Sinnoh). Cherrim is a Stage 1 Grass Pokémon with 80 HP. The card lists level 26. The card says it evolves from Cherubi. In this catalog that name is Cherubi (#420).

Cherrim (#421) has 11 other cards in the catalog. Those other cards are in 11 sets. The other printings with a release date run from 2008 to 2026. The earliest other card is Cherrim 6/17 in POP Series 8 (2008). Both list 80 HP. Both list the rarity Uncommon. 1 other cards of Cherrim list a different HP.
The illustrator line reads Atsuko Nishida. I count 408 other cards in the catalog with that illustrator.
Diamond & Pearl set binder is where a full Diamond & Pearl set goes. This card fills one slot there. A generation binder holds one card of each species. Cherrim can fill a slot in Generation 4 binder (Sinnoh). Themed lists that include this exact card are Sweets and snacks Pokémon, Atsuko Nishida cards, early series, and Flower Pokémon. I still need this card.
