Corybas hypogaeus is a species of terrestrial orchid endemic to the New Zealand.[2] It is part of the C. trilobus aggregate, whose members are characterized by a funnel or dish-shaped labellum and an often heart or kidney-shaped solitary leaf.[1]
Description
Corybas hypogaeus is a
Corybas hypogaeus can be distinguished from other members of the C. trilobus aggregate by its the diminutive flower, which is commonly buried in leaf litter, and its characteristically jagged, cupped labellum.[3] It is highly similar to the recently described species C. sanctigeorgianus, from which it can be distinguished by its labellum with a green-tinted center, rather than creamy white, and its dorsal sepal equal to the length to the labellum or slightly longer (rather than noticeably longer). Moreover, C. sanctigeorgianus is only known from select sites on the North Island.[1]
Taxonomy
Corybas hypogaeus was first described by William Colenso in 1884 under the name Corysanthes hypogaea. The
Distribution and habitat
Corybas hypogaeus is endemic to New Zealand's North Island and South Island. In the North Island, it is known from the Hunua Ranges, Waikato, and Wairarapa. In the South Island it is known only from north-west Nelson. It grows in lowland to montane habitats in kānuka or southern beech-dominated forest and is usually found near the trunks of these trees or on the borders of swamps within the forest, half-buried in deep drifts of decaying leaves. The leaf of the plant is usually all that is exposed.[3]
