Charles Schweinfurth was an American botanist and plant collector who distinguished himself by his studies on orchids. He predominantly collected species from Peru which he described in his four volume reference work Orchids of Peru (1958). He was a researcher at the Botanical Museum of Harvard University, and director of the Ames Orchid Herbarium where, in 1958, he was succeeded by Leslie Andrew Garay.

Pterostylis parca commonly known as the Lithgow leafy greenhood is a plant in the orchid family Orchidaceae and is endemic to New South Wales. Non-flowering plants have a rosette of leaves on a short stalk. Flowering plants lack a rosette but have up to eight translucent pale green flowers on a flowering stem with three to six stem leaves.
Pterostylis prasina, commonly known as the mallee leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to southern continental Australia. Non-flowering have a rosette of leaves on a short stalk, but flowering plants lack the rosette and have up to eight pale green and translucent green flowers with darker green lines. The flowers have a pale green labellum with a darker central line. It is a common and widespread greenhood in parts of Victoria and South Australia.

Flowering plants have up to six shiny, translucent green flowers with darker green stripes. The flowers have an insect-like labellum which is green with a dark green mound on its upper end. Non-flowering plants have a rosette of leaves on a stalk, but flowering plants lack the rosette, instead having between four and eight stem leaves.
Pterostylis tenuis commonly known as the smooth leafy greenhood is a plant in the orchid family Orchidaceae and is endemic to New South Wales. Non-flowering plants have a rosette of leaves on a short stalk. Flowering plants lack a rosette but have up to four shiny, translucent green flowers on a flowering stem with three to six stem leaves.
Pterostylis umbrina, commonly known as the broad-sepaled leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to the Australian Capital Territory and New South Wales on the Southern Tablelands. As with similar greenhoods, plants in flower differ from those that are not. Those not in flower have a rosette of leaves flat on a short stalk. Plants in flower have up to six green flowers with darker green stripes with stem leaves but lack a rosette.
Calochilus caeruleus, commonly known as the wiry beard orchid, is a species of orchid native to northern Australia and New Guinea. It has a single leaf which continues to develop during flowering and up to twelve greenish flowers with reddish brown markings and a labellum with a red "beard".
Trachoma, commonly known as spectral orchids, is a genus of flowering plants in the family Orchidaceae. Orchids in this genus are epiphytic plants with leafy stems, crowded, leathery leaves arranged in two ranks and a large number of relatively small, short-lived flowers that often open in successive clusters. The sepals and petals are free from and more or less similar to each other, except that the petals are often smaller. The labellum is rigidly fixed to the column and is more or less sac-shaped. There are about 17 species distributed from Assam to the Western Pacific Ocean. Most species grow in rainforests, often on emergent trees such as hoop pine.
