It is top heavy, so it is good that you secure the plant by putting it in a heavy container. All of mine are either in thick thick clay pot or in a thin plastic pot slid in heavy container.
Did you mentioned soggy moss??? try and let it dry out. or try to keep them plant rather bright and warm. Do not water until the moss gets bone dry.
Yours do not have many leaves left, which find odd, but since it does not have many leaves and no new growth yet, it can be kept rather dry.
It is dendrobium hybrids as others mentioned.
This plants does best in very bright and warm conditions year around, but cooler (although nothing under 60, which is still pushing it a bit) and drier winter is acceptable.
I grow these in bark mix. Any fast draining mix with some moisture retention is great for these. During the warm season when the plant is in growth mode, water and fertilize heavily. These usually flower in the fall, but can bloom whenever they want.
At least mines do. most of them bloom in the fall, but then there is always one or two that bloom at any time of the year. spring, summer, winter...
easy plants, but very beautiful and long lasting!!!
