Botanist found Plant thought to be extinct for more than 135 years

A Botanical team of researchers have “rediscovered” a rare plant species called Globba andersonii from the Sikkim Himalayas found near the Teesta river valley region after a gap of nearly 136 years. The plant, known commonly as ‘dancing ladies’ or ‘swan flowers’ was thought to have been extinct until its “re-collection”, for the first time since 1875.

Key-Points

Globba andersonii are characterised by white flowers, non-appendaged anthers (the part of a stamen that contains the pollen) and a “yellowish lip”.

The earliest records of the collection of this plant were dated between the period 1862-70 when it was collected by Scottish botanist Thomas Anderson from Sikkim and Darjeeling.

Then, in 1875, the British botanist Sir George King, had collected this taxon from the Sikkim Himalayas.

The plant Globba andersonii is commonly known as ‘dancing ladies’ or ‘swan flowers’.

Classified as “critically endangered” and “narrowly endemic”, the species is restricted mainly to Teesta River Valley region which includes the Sikkim Himalayas and Darjeeling hill ranges.

The plant usually grows in a dense colony as a lithophyte (plant growing on a bare rock or stone) on rocky slopes in the outskirts of evergreen forests. It is especially prevalent near small waterfalls along the roadside leading to these hill forests, which are 400-800 m. above sea level.
