There are three species of Pabstia recorded ( Flora do Brasil) in the Rio de Janeiro state:
Pabstia jugosa
Pabstia placanthera
Pabstia viridis
The photos I found of Pabstia placanthera don't show that bulbous leaf lase.
Pabstia jugora has them but the plant looks too small..

Pabstia viridis is the only possible but I cannot find a detailed photo of the bulbous base.
The flowers look gorgeous of that one, a pity mine wasn't in bloom. But I still don't have an idea of the size of the plant..
