moth orchid
Phalaenopsis Blume
A genus overview; characteristics vary between its species.
Moth orchids take their name from the resemblance of some flowers to large moths. Most species live on trees, but the genus also includes plants growing on rocks or in the ground. Some inhabit continuously humid forests, while others endure seasonal dryness or cool weather by losing leaves and entering a resting period.

Recognizing the plant
The usually short stem carries fleshy leaves in two ranks, often hiding beneath their overlapping bases. Leaves can be plain green, marbled, or tinged purple or silver. Flowering shoots arise from the leaf axils and may stand upright or hang downward, branching in some species. Flowers open together or successively and are often long-lasting. The lip is typically three-lobed and may carry raised calluses or slender, curling appendages. Pollen is concentrated into two or four masses attached to a shared adhesive structure.
