I've yet to come across one. I haven't seen it when going to dream island, I haven't seen it on peoples' share shelves, and I haven't seen anyone growing it, but according to Serebii, it's obtainable. Is it just a mistake on their part or is the Pamtre Berry just really rare?

I'm not sure if it's from White Forest, but there's a Bluk Berry available somewhere in Black and/or White (not from Dream World). --- Still putting some level 1 female Drought Vulpixes (legit) on GTS for a Patrat every day :) (Preschooler Tom of USA-Minnesota)
I got a Bluk Berry from my White Forest. AFAIK it's just there to be sold to the lady west of Nimbasa. --- "Murder of the living is tragic, but murder of the idea is unforgivable." - Janus, speaker of the synod
