Pretty miniature aroid from Santiago, Ecuador.  Leaves only reach about two inches.  It looks like a mini pteromischium section type.  Very succulent/thick leaves and a slow growth habit, stems are similarly thick for a small aroid.  Would do great in any size enclosure.  This plant originally came in on an import from Ecuador.

Available plants are well rooted in 2″ pots.  The main photo is representative of plants available.
