Taxonomie : ​Espèce placée dans Ruellia sect. Strobiliformes E.A.Tripp & T.F.Daniel 2023 à titre provisoire, sur la base du protologue dans lequel R. schnellii Wassh. 2002 est comparée à deux espèces classées moléculairement dans cette section R. tubiformis Kunth 1818 & R. tetrastichantha Lindau 1900. D'après Wasshausen (2002): "Ruellia schnellii resembles R. tubiflora H.B.K. var. tubiflora and R. tubiflora H.B.K var. tetrastichantha (Lindau) Leonard from Costa Rica, Panama, Venezuela and Colombia by its general habit and inflorescence but may be distinguished from the latter by having narrowly elliptic to oblong, 9-12 by 2.5-4.0 cm leaf blades, a smaller corolla, 0.6-0.8 mm broad at throat and the limb about 20-22 mm broad, and the distinctly bicolored foliose bracts subtending the short terminal spike. In contrast, R. tubiflora has oblong-elliptic, 6-24 by 6-9 cm leaf blades, a distinctly larger corolla, 10-15 mm broad at throat and the limb about 30 mm broad, and leafy, not bicolored foliose bracts subtending the short terminal spike."​
