Gleason (1929) made the transfer oi Lisianthus
quelchii N. E. Brown to Symbolanthus quelchii
(N. E. Brown) Gleason without comment.
He cited Tate 397. collected on Roraima, as belonging
to this species. Ewan (1948) said: "This Roraima endemic is most closely related, as N.
E. Brown originally pointed out, to Lisianthus
ovalis R. & P., that is, to Macrocarpaea ovalis
(R. & P.) Ewan ofthe present treatment." This
is a rather curious geographic alignment, even in
view of the more limited material of 25 years
ago. The immediate relative is M . tepuiensis, including
Ewan's own M . cerronis and M . salicifolia,
