The characters of this species are midway between T. brachyceras, which is smaller in all its floral parts, and T. beuthii, which distinctly exceeds it in corolla size and spur length. The two most useful characters are the peduncle, which is twice that of T. brachyceras and its stout, conical spur of no more than ca 6 mm long, as opposed to the slender equivalent of T. beuthii, never less than ca 8 mm. A frequent tendency for flowers to cluster at 'telescoped' internodes is also a helpful characteristic (Watson & Flores, 2011c)
