Just over two years ago I got a large Maxillaria picta. It was from a collection close-out and cost only a couple of dollars. I took it apart but the roots were so tightly intertwined that I ended up with lots of small pieces. This is the largest of those.
Maxillaria picta grows in Brazil and Argentina. It is a high light cool to warm growing plant, blooming in winter and spring. The genus Maxillaria (Max) contains 650 some species spread throughout the tropical and sub-tropical Americas. They have a single flower. Generally warm to hot growing.
This is not a strong plant and it has some scale on it. It is going to get up-potted along with a complete cleanup including spraying the roots. I will also check and spray the plants sitting near it.
