Triphora trianthophoros, the threebirds [1] or three birds orchid, or nodding pogonia, is a species of terrestrial orchid native to eastern North America.
Triphora trianthophoros is a small, terrestrial, semi-saprophytic orchid. [2] The showiest member of its genus, T. trianthophoros has 1-8 (often 3, thus the name) nodding flowers that are roughly 2 cm in size and sit atop stems 8–25 cm tall. Leaves are small (~1 cm X 1.5 cm) and typically dark green to purple. The orchid blooms from July through September, but is infamous for its elusive nature, with ephemeral flowers lasting for only several hours on a few days of the year. [3] It has further been reported that populations across a region synchronize blooming on specific days, making observation of flowering specimens even more difficult. [4] Several forms of T. trianthophoros exist, including forma albidoflava (Keenan) with white flowers, forma caerulea (P.M. Brown) with blue flowers, and forma rossii (P.M. Brown) with multi-colored flowers. [5] [6] [7]
Triphora trianthophoros is native to the eastern North America, ranging from as far south as Panama and north through Central America and the central and eastern United States into Ontario. [2] Despite its wide distribution, the species is rare throughout much of its range and has been given G3G4 (secured, but with cause for concern) conservation status by NatureServe. [8]
Triphora trianthophoros is usually found in mixed deciduous forests. Co-located species often include partridgeberry and beech trees. [2] [3]
Arethusa bulbosa, commonly called dragon's mouth orchid, is the only species in the orchid genus Arethusa. The genus is named after a naiad of Greek mythology. This monotypic genus is abbreviated Aret in trade journals.

Neottia convallarioides is a species of orchid known by the common names broad-lipped twayblade and broad-leaved twayblade. It was formerly placed in the genus Listera, but molecular phylogenetic studies have shown that Neottia nidus-avis, the bird's-nest orchid, evolved within the same group, and all species of Listera have been moved to Neottia.

It is native to Arizona, New Mexico, Texas and Coahuila. It is closely related to H. arizonica and the two are sometimes considered varieties of the same species. Hexalectris spicata is endemic to the southern half of the United States from Arizona east to Florida and north to Maryland and the Ohio Valley.
