Diagnosis:— This species is distinguishable from the closely related species Premna chrysoclada , and P. tanganyikensis by its life form of scandent shrub or liana (vs shrub or small tree, occasionally scandent in P. chrysoclada , and shrub or small tree in P. tanganyikensis ), older stems with persisting thorns, not ridged and not corky (vs without persisting thorns, but ridged, and somehow corky in P. chrysoclada and without persisting thorns, not ridged, but thinly corky in P. tanganyikensis ), branchlets, petioles, and inflorescences densely golden-brown dendritic pubescent (vs with very densely rusty or orange-brown pubescent in P. chrysoclada , and densely orange ferruginous pubescent in P. tanganyikensis ), inflorescence short cyme on lateral and terminal shoots (vs elongated much-branched terminal cymes in P. chrysoclada , and short dense terminal and axillary cyme ovoid clusters on short lateral shoots in P. tanganyikensis ), and calyx tubular, ca. 3 mm long, lobes broadly triangular, ca. 1 mm long, densely dark brown dendritic-pubescence (vs cupular, 1.8 mm, lobes truncate, 0.5 mm long, glandular, densely stellate-pubescence in P. chrysoclada , and tubular, ca. 3 mm long, lobes triangular, ca. 1 mm long, dense ferruginous stellate-pubescence in P. tanganyikensis ) ( Table 1).
