What is corybas cordatus?

Corybas cordatus is a species of orchid native to the forests of New Zealand. It is commonly known as the Heart-leaved Helmet Orchid, due to the shape of its leaves. The plant is small and only grows up to 10 cm tall. It produces a single flower on a long stem that can reach up to 20 cm in length. The flower is typically reddish-brown or greenish-brown and is shaped like a helmet or hood, hence the name "helmet orchid." The species is rare and protected under New Zealand law. It is also listed as vulnerable by the International Union for Conservation of Nature (IUCN) due to habitat loss and fragmentation.
