About Earina
Earina is a genus of orchids belonging to the family Orchidaceae, comprising seven recognized species. These orchids are primarily distributed across various islands in the Pacific Ocean. The New Zealand species within this genus are particularly notable for their characteristic growth habits and floral displays.
Growth and Habitat
In New Zealand, Earina orchids are commonly found growing as epiphytes, attaching themselves to mossy trunks of trees, or as lithophytes, thriving on rocks. These habitats are typically found within the rain forests of both the North and South Islands. The plants possess strap-shaped leaves that emerge from pendulous, wire-thin pseudobulbs, which in turn arise from creeping rhizomes, indicating an adaptation for clinging to surfaces and spreading.
Floral Characteristics
The flowers of Earina orchids are notably tiny, usually measuring less than 1 centimeter across. However, despite their diminutive size, they are produced in great abundance. This prolific blooming can result in a spectacular visual impact when a large specimen is in flower within its natural bush environment. Some species, such as Earina autumnalis, are recognized for their fragrant flowers, adding an olfactory dimension to their appeal. The blooming seasons vary, with E. mucronata flowering mainly in spring and E. autumnalis blooming in autumn.

Related Orchid species
Cryptostylis
Cryptostylis, commonly known as tongue orchids, is a genus of terrestrial orchids found in South Asia, Southeast Asia, and the South Pacific. These orchids are distinguished by their prominent labellum, which is the most conspicuous part of the flower, and their unique pollination strategy involving wasps attempting to mate with the flowers. At least some species are pollinated through a process called pseudocopulation, where male wasps mistake the flower for a female wasp.
Corybas
Corybas, commonly known as helmet orchids, is a genus of about 120 species of small, perennial, terrestrial herbs in the orchid family. Native to a wide range including Australia, New Zealand, Southeast Asia, and the Himalayas, these orchids are distinctive for their single, fungus-like flower, dominated by a large dorsal sepal and labellum, often resembling a helmet.
Collabium
Collabium is a genus of flowering plants belonging to the orchid family, Orchidaceae. These terrestrial orchids are found growing in shaded forest conditions across Southeast Asia, with a distribution spanning from the Himalayas in India and Burma to China and extending to various island groups in Malaysia and the Pacific.
