Scientific name: Homoranthus elusus
Gazetted date:
15 May 2020
Profile last updated:
14 Oct 2024
Description
Homoranthus elusus was first described by Copeland et al. (2011) as an “Erect shrub, glabrous. Leaves opposite, decussate, punctate, 8–13mm long, 0.2–0.4mm wide, 0.4–0.8mm thick, linear, mucronate, petiolate; blade in side view straight to incurved linear; petiole 0.6–1.1mm long. Flowering branchlets undifferentiated, with 2–4 flowers held erect in leaf axils at branchlet apex. Inflorescence a monad; peduncles 1.0–1.5mm long; bracteoles caducous, 4–7mm long. Hypanthium cylindrical, 5-costate,tuberculate between the ribs, with rounded, multicellular trichomes, 3.8–5.2mm long. Sepals 5, the apex distally laciniate with 3–6 slender processes, 2–2.5mm long. Petals 5, broadly obovate, the apex obtuse,2.0–2.5mm long, the margin entire. Stamens 10; filaments ~0.6mm long; anthers globose, basifixed,yellow. Staminodes 10, alternating with the stamens, distinctly adnate to the adjacent antepetalous stamen. Style 8–10mm long, exceeding the hypanthium by 4–6mm at anthesis, minutely hirsute below the papillose stigma. Ovary unilocular; placenta sessile, axile-basal. Fruit a dry, indehiscent nut, brown. Homoranthus elusus is most similar to H. bruhlii from which it can be distinguished by its thinner leaves(0.4–0.8mm in H. elusus compared with 0.8–1.4mm in H. bruhlii). In addition, H. elusus also has several rounded, multicellular trichomes between the hypanthium costae – these trichomes are absent from the hypanthia of H. bruhlii. Although H. elusus was originally identified as H. biflorus on the label of the holotype, the two species are not closely related and H. elusus can be easily distinguished by the flowering branchlets being undifferentiated. In contrast, the flowers of H. biflorus are arranged in pairs on a strongly modified internode that superficially resembles a peduncle.”
