The?ata?eficient (??) category is applied. <b>PHENOLOGY</b>. Flowering and fruiting in July. <b>NOTES.</b> <i>Gomphostemma stellatohirsutum</i> is a distinctive species recognised by its flowering calyx indumentum of dense stellate hairs and cymes subtended by cluster of small leaflike bracts, 3 – 12 mm wide. It is morphologically similar to <i>G. hirsutum</i> from Sabah, both species having dark brown stems with long branched hairs.
