Howdy TFF,
I've got a hand full of Pachylobus macrophyllus. This species has been highly sought after and has only until recently become available from a source inside Cameroon. This species is a tropical equatorial species, although it appears to have some cold tolerance as my personal seedlings have survived in a hoophouse experiencing ~33*F temperatures with no damage whatsoever. Check it out, get stoked!
