Phalaenopsis (/ ˌ f æ l ɪ ˈ n ɒ p s ɪ s /), also known as moth orchids, [2] is a genus of about seventy species of plants in the family Orchidaceae.Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end.
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 Phalaenopsis species with horizontal stems, such as P. hieroglyphica, the leaves are pendant and grow downward to drain rainwater away from the plant. The reproductive organ is the column, found between the two largest petals of Phalaenopsis orchids. The lip, connected to the flower by the column, aids in pollination.
There are several subspecies and also hybrids, rendering the identification of this species more difficult, but typically, the flowering spike is robust with a hollow stem, 25–60 cm tall, and bearing up to 50 flowers. Plants grow to a height of from 15 to 70 cm. The 4–7 erect yellowish-green leaves are hooded at the tip.
Leaves typically start to appear above ground in late autumn and are often beginning to yellow by the time the flowers appear, [4] which in the case of O. scolopax is between March and June in their native habitats. The flower spike is very variable in height, usually 10–50 cm (4–20 in) tall, but occasionally up to 90 cm (3 ft).

Prasophyllum spicatum was first formally described in 1991 by Robert Bates and David Jones from a specimen collected near Dergholm State Park and the description was published in Australian Orchid Research. [1] [2] The specific epithet (spicatum) is a Latin word meaning "in a spike" referring the dense flower spike of this species. [2]
