Nomenclatural note. Among the specimens collected in the western African tropical mountains by Gustav Mann, Veronica mannii is closely related and currently treated as subspecies of the otherwise East African montane V. glandulosa, which Hooker (1862) even alluded to in the protologue. It is supposed to differ by narrow leaves and sepals and bracts shorter than the flowers (Hooker 1862). The main collection of Mann is in Kew, but duplicates have been sent around widely. However, care must be taken since Mann collected several specimens of the taxon under different numbers. Therefore, the specimen in P[P03558680], which has only a label “Mann 1859-1863” with no. “2090” is only a syntype.
