摘要：
Asplenium arcumontanum (Aspleniaceae), a new terrestrial forest species from northern Tanzania, is described and illustrated. This taxon is closely related to the more widespread A. elliottii, a vicariant species with similar habitat requirements but a near-allopatric distribution. Asplenium arcumontanum fits the typical altitudinal zonation pattern of equatorial African gemmiferous ferns, and the endemism pattern of the Eastern Arc Mountains. Its restricted distribution further underscores the urgent need to conserve residual forest patches in this distinctive range.
