Goodyera
Goodyera
Goodyera, commonly known as rattlesnake plantain or jade orchids, is a widespread genus of orchids found across Europe, North and Central America, Australia, and various islands. These terrestrial orchids are distinguished by their rosette of leaves at the base, often marked with white or pale green, and typically bear numerous small, white, resupinate flowers. They are differentiated from similar genera like Spiranthes by their creeping rhizome, leaf shape and coloration, and the presence of a small pouch on the labellum.

About Goodyera
Goodyera, a genus commonly known by names such as rattlesnake plantain, jade orchids, and ladies' tresses, represents a diverse group of orchids within the tribe Cranichideae. Approximately 100 species have been formally described, with a significant concentration of diversity found in East Asia. The genus's reach extends across continents, encompassing regions such as Europe, Madeira, North and Central America, Australia, and a wide array of islands from the west Indian Ocean to the Pacific Ocean.
Description and Characteristics
Plants belonging to the genus Goodyera are predominantly terrestrial. They are characterized by a fleshy, creeping rhizome from which a loose rosette of leaves emerges at the base of the flowering stem. These leaves are typically elliptic in shape, notably asymmetrical, and possess a green coloration often adorned with white or pale green markings. A distinctive feature of the entire plant, excluding the flowers, is the presence of slightly sticky hairs. The inflorescence usually bears numerous small, resupinate flowers. The structure of the flower involves the dorsal sepal and petals overlapping to form a hood over the column, while the lateral sepals spread widely. The labellum is unlobed and features a small pouch.
Taxonomy and Distinguishing Features
The genus Goodyera was first formally described by Robert Brown in 1813. However, its precise generic delimitation remains a subject of discussion among botanists, with some advocating for a more restricted circumscription of the genus. In horticultural contexts, the genus is abbreviated as 'G.'.
Goodyera orchids share similarities with orchids of the genus Spiranthes. Key differences that distinguish them include the presence of rhizomes in Goodyera, which are absent in Spiranthes. Furthermore, Goodyera species typically have leaves with characteristic shape and color patterns, often asymmetrical and marked, whereas Spiranthes species display plain green leaves and lack pouched labella. The labellum of Goodyera also possesses a small pouch, a feature not found in Spiranthes.
