      This is a lovely orchid site! We just received a donation, an orchid collection, to Dokmai Garden, and we currently establish a catalogue. I need to know for sure if it is Chiloschista viridiflora or viridflava, as Queen Sirikit Botanical Garden as well as Smitinand’s checklist claims “viridiflora”. I do not have accss to the protologue - has anyone seen it (Orchids-flowers April 19th)?
      Thanks, Eric Danell, scientific consultant at Dokmai Garden, Chiang Mai. http://www.dokmaidogma.wordpress.com

      I also need to know which spelling is correct: Nervillea (According to GBIF and Nantiya’s orchid book) or Nervilia (according to QSBG and Smitinand’s checklist)? I can only accept an answer from somebody who checked the actual protologue, as errors can be repeated and perpetuated on internet. Thanks again, Eric Danell, Dokmai Garden.

      Dear Mr Danell,
      We checked again the name,
      this time with Kew Garden.
      The real name is
      Chiloschista viridiflava Seidenf.
      You can try it by yourself:
      For the other variation (chiloschista viridiflora) which is also covered in Queen Sirikits Book,
      there are no search results at Kew Garden,
      which is an expert in orchidology.
