Rediscovery Trichotosia mollis (Schltr.) Kraenzl., 1911
Trichotosia mollis (Schltr.) Kraenzl., transfer to properly genus by Kraenzl. at year 1911, from basionym named as Eria mollis Schltr., published at year 1906. Original specimen taken from Sungei Lalah, near Indragiri, Riau and Batang Palupu in West Sumatra, the altitude were not recorded. Endemic.

The last report and update about this species made by J. J. Smith, he made addition description and published in Blumea 5 : 740 (1945), who mentioned that puberous callus at the base of the column foot is evidently the bearded underside of the column.

It is meaning about 67 years after J. J. Smith make review about this orchid, no more review founded. There is no photo documentation. For deternining ID, we can learn from protolog description and compare specimen with drawlines made by J. J. Smith, published in year 1934.

New specimen, in isotype location found in Barisan series hill.from Rejang Lebong regency, Bengkulu, South West Sumatra by Mr. Leicneagra on Christmas day 25 December 2012 .

Specimen rediscovery found by  Mr. Leicneagra and Mr. Agung on 25 December 2013

They tell and sent to me a few photo for prelimenary determination ID. They inform me the plant is a bit flattened and pendulous.

Plant when taken from in situ.

On 27 Janury 2013, the specimen flowering and full bloom. Mr. Leicneagra make capture the flowers and sent to me for examination. Today (28 January 2013) I read protolog description made by Schltr. year 1906. Than try ro examination many photo to draw line made by J. J. Smith publish in year 1934. The result is all fix and fide with Trichotosia mollis (Schltr.) Kraenzl., 1911, a species lost of orchids Sumatra.
