Gomesa praetexta (Rchb.f.) M.W.Chase & N.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 praetextum Rchb.f. in that genus.

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

My preference is to use a narrower generic concept and recognise this as Brasilidium praetextum (Rchb.f.) Campacci.

Love the third image, the amber-tan colour is unusual and the veins in the flower parts can be seen quite clearly.


all good

I think they are all good Bernard...
I especially like the one the post is based on...the one at the bottom with the single flower in closeup. EDIT: oops we were both talking about the same one I think

Imagine what the flowers on this little plant will be like in a few years as a specimen!

Another cracker of a post Horst!

Regards wellsy

Selfing of Onc. praetextum/enderianum

This plant is a seedling from one of our selfings we did with this species some time ago.

first or best?

so is it simply the first to flower or the best of the four?

Regards wellsy

The lucky one.

It is one of the few who made it. Many of them were not so lucky. We made some mistakes.
Then it is the first plant blooming during my presence in Brazil. This happens only 3 times a year.
