Orchid Borealis

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...

This species is from the State of Rio de Janeiro in Brazil.   GBIF has a record from Nova Friburgo , a municipality in the State of Rio de Janeiro.  Neubig et al (2012) mentioned a report from near Caracas , Venezuela, which is far from Rio de Janeiro and may be an escape from cultivation. With the current knowledge, this species belonging to a monotypic genus (a genus with only one known species) is justified, but the relationship of this genus to others is not completely understood yet (in my interpretation of the data).  This species was originally described as Oncidium limminghei in 1855.  It was moved to a monotypic Psychopsiella in 1982.  Subsequently, based on nuclear ITS sequences, Chase (2005) lumped this species into genus Psychopsis . This species does look like a miniture Psychopsis if you look at the patterned leaves, so this seemed to be logical.  However, a later study with additional data (6 regions of chloroplast sequences; cpDNA...

I got this from Troy Meyers Conservatory: TN6953 , 'Blanco 3219' × self, Seed Donor: Mario Blanco, Pollination: Oct 2009. It is still a small plant, but it seems to flower freely. It is an easy grower, and I'm looking forward it to become bigger. Currently it is mounted on tree fern. This species is from Brazil.
