In the protologue this species was said to be similar to Spiradiclis oblanceolata, although this species was classified in S. subg. Spiradiclis while S. oblanceolata was classified in S. subg. Sinospiradiclis. The protologue of S. baishaiensis apparently described short-styled flowers (cf. f. 3, f. 4, and description of style as half as long as corolla and anthers exserted); however, H. S. Lo (in FRPS 71(1): 106. 1999) reported this to be a description of a long-styled flower. The protologue described the corollas as pubescent near the middle inside, while H. S. Lo described the corollas as bearded in the throat.
