However, it differs from <i>L. chinensis</i> by having coriaceous leaves with 7–9 pairs of nerves and parallel veinlets; stipules triangular-lanceolate, strigillose, 5 mm long; flowers usually 4-merous as well as drupes with 4 pyrenes. It differs from <i>L. verticillatus</i> by having strigillose hairs on young branches and leaf nerves beneath; stipules triangular-lanceolate, strigillose, more than 5 mm long; flowers usually 4-merous; calyx with strigillose triangular lobes, and drupes with 4 pyrenes and verrucose on external surface. <i>Lasianthus trichophlebus</i> subsp. <i>barbellatus</i> was considered to be different from the typical subspecies by having relatively small and elliptic leaves. After more Malesian specimens were examined, it became clear that <i>L. trichophlebus</i> subsp. <i>barbellatus</i> cannot be separated from <i>L. trichophlebus</i>.</p>
