Rodriguezia brachystachys

I received this as Rodriguezia pardina from Florália in May 2018.  The flowers aren't as showy as some of the species in this genus, but it is a nice compact species (about 6cm high). But when it flowred first time in 2019, it turned out to be Rodriguezia brachystachys.  I looked for not information about this species, but I didn't have much info.  According to Flora do Brazil (link), it occurs in Minas Gerais and Federal District. It is also listed in the checklist of orchids from Federal District, Brazil (Batista & Bianchetti, 2003), but removal from the checklist was suggested because there was no herbarium collection or record (Queiroz 2015, Queiroz et al. 2015).  This site indicates its occurence in Rio de Janeiro, too.

Mine is still small, but Mauro Rosim has a photo of his well-grown specimen of this species in his Flickr (link).  I've been growing at the cool-end of intermediate, but I'm not sure if it will do better warmer. I have it mounted to a cedar shingle without any sphagnum moss.  I'm growing it at PPFD of 80 µmol m^-2 s^-1.
