Gomesa longipes (Lindl.) M.W.Chase & H.H.Williams

Hi Horst,

Oncidium is one of the genera that has recently undergone a revision based upon DNA and morphological studies. The World Checklist now recognises a broadly expanded genus Gomesa R.Br. and includes Oncidium longipes Lindl. in that genus.

Although I don’t agree with that transfer, the World Checklist is calling this Gomesa longipes (Lindl.) M.W.Chase & N.H.Williams.

My preference is to be more consistent and use a narrower generic concept. I prefer to recognise this species as Kleberiella longipes (Lindl.) V.P.Castro & Cath.

Cheers.

Gary
