hello everybody,
this week i bought a couple more plants, which is really bad because i'm running out of space and some of them are really big.
i bought a couple plants of comparettia falcatta, two maxillarias, an acineta (probably superba) about to bloom, a really big phaius tankervillae, a couple more stanhopeinae, a catasetum callosum that is also about to bloom, and... This






i have absolutely no idea of what can it be.
so i would really appreciate some help, even if it's only the the tribe of subtribe

thank you
