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).
