The plant has a short, stout, creeping stem carrying up to 12, curved, fleshy, deeply channeled, keeled, retuse apically leaves and blooms on an axillary ...
Group of plants Inflorescence. Orchis purpurea reaches on average 30–100 centimetres (12–39 in) of height. The leaves are broad and oblong-lanceolate, forming a rosette about the base of the plant and surrounding the flower spike.

In each flower the sepals and side petals are gathered together to form a pointed "helmet" (whence it gets its name), a lilac colour outside and a veined purple colour inside. The central tongue finishes in two lobes separated by a tooth.
The list of genera alone currently stands just short of 1000 entries. From a cladistic point of view, the orchid family is considered to be monophyletic, i.e. the group incorporates all the taxa derived from an ancestral group. The taxonomy of the orchids is explained on the page Taxonomy of the orchid family.
The flower secretes a fluid (see Coryanthes alborosea picture) into the flower lip, which is shaped like a bucket. The male orchid bees (not the females) are attracted to the flower by a strong scent from aromatic oils, which they store in specialized spongy pouches inside their swollen hind legs, as they appear to use the scent in their ...

It is often united with the column and can be ...
