Lecanorchis taiwaniana has been recently discovered in Assam.
It is one of India’s smallest orchids in terms of size and duration of bloom to be recorded botanically.
The orchid, discovered earlier in Japan, Taiwan, and Laos, is found to have a maximum height of 40 cm and a blossoming period of five-six days.
Lecanorchis taiwaniana is a myco-heterotroph – one of the parasitic plants that have abandoned photosynthesis.

Abandoning Photosynthesis

There are a number of flowering plants that have abandoned photosynthesis, and these fall into two categories: haustorial parasites and myco-heterotrophs. (It is also called, parasitic plant, as both these groups derive their nutrients from another plant).
The difference is that haustorial parasites feed directly on another plant via a modified root called the haustorium.
Mycoheterotrophs obtain their nutrition indirectly from the plant via a mycorrhizal fungus. The mycorrhizal fungus, attached to the roots of a photosynthetic plant, thus acts as a bridge between that plant and the mycoheterotroph, such that nutrients (carbon) flow from plant root, to mycorrhizal fungus to the myco-heterotroph.
