Kopsia obscura D.J.Middleton, sp. nov.
Similar to Kopsia fruticosa (Roxb.) A.DC. in the pink corolla but differs in the smaller
stature (shrub to 50 cm tall in K. obscura, shrub or tree to 6 m tall in K. fruticosa),
glabrous branchlets (pubescent in K. fruticosa) and mostly narrower corolla lobes (5–
5.7 mm wide in K. obscura, 5.5–16 mm wide in K. fruticosa). Also similar to Kopsia griffithii King & Gamble in general appearance, especially in the leaves, but differs
in inflorescence structure (shorter and more congested in K. obscura), corolla colour
(pink in K. obscura, white with yellow ‘eye’ in K. griffithii) and nectary indumentum
(glabrous in K. obscura, pubescent in K. griffithii).
Etymology. The specific epithet obscura reflects the lack of information available on the origins of this species.
