Doubtful Species
- Sophronitis pterocarpa Lindl. Wing Fruited Sophronitis (Brazil to Paraguay).
- The type of S.pterocarpa is from the city of Rio de Janeiro, where only S. cernua occurs. The belief that this species corresponds to the western portion of the range into Paraguay does not match herbarium information.
- Sophronitis tereticaulis (Hoehne) Van den Berg & M.W.Chase: Twisted-stem Sophronitis (Brazil - Minas Gerais).
- This taxon is a variation of S. mirandae which occurs only within some populations, with no biological grounds for species recognition.

Famous quotes containing the words doubtful and/or species:
“It is doubtful whether anyone who has travelled widely has found anywhere in the world regions more ugly than in the human face.”
—Friedrich Nietzsche (1844–1900)
“Books, gentlemen, are a species of men, and introduced to them you circulate in the “very best society” that this world can furnish, without the intolerable infliction of “dressing” to go into it. In your shabbiest coat and cosiest slippers you may socially chat even with the fastidious Earl of Chesterfield, and lounging under a tree enjoy the divinest intimacy with my late lord of Verulam.”
—Herman Melville (1819–1891)
