Description
Species Description - Trees to 10 m. Branchlets slender, midway along flush 2-3 mm diam., distally weakly angular, soon terete, sparsely grey-strigillose, the surface clearly exposed, dark brown to black, the hairs very short, to 0.1 mm, appressed; terminal buds slender, 3 × 0.6 mm, densely chalky-white sericeous. Leaves alternate, widely and evenly spaced along current flush; petioles slender, to 1.5 × 0.2 cm, canaliculate, the indument as on branchlets; laminae membranaceous or chartaceous, plane, elliptic-ovate, 10-17 × 3-8 cm, the base obtuse to acute, attenuate, the apex acute, acuminate for up to 2.5 cm, the margins minutely recurved throughout; upper surface blackish green to dark or olive-brown, minutely punctulate, the primary to fourth-order veins raised, their prominence decreasing with rank; lower surface glabrous except for barbellate tufts in the axils of the sparsely strigillose midrib and secondary veins, all vein orders raised, their prominence decreasing with rank; secondary veins 4-6 per side, ± evenly spaced, slightly more distant around midlamina, patent, diverging at 70-85° (more obtusely around midlamina), abruptly ascending after midcourse, brochidodromous; tertiaries roughly horizontal, between secondaries straight to once-forked. Staminate inflorescences evenly spaced along current flush in the axils of foliage leaves, to 5 cm long with 5 lateral branches, branch orders 2-3, the highest order dichasial, lax, the flowers distant, the axes sparsely strigillose; bracts and bracteoles caducous by anthesis, narrowly ovate to lanceolate, the indument as on axes; pedicels terete, to 5 mm long, those supporting secondary flowers slightly shorter. Flowers hypocrateriform, 3.5 mm diam., sparsely grey-strigillose outside, the indument denser towards tepals; receptacle infundibuliform, 1 × 1 mm, sparsely grey-pilose inside, the hairs straight, erect. Tepals membranaceous, ovate, 1.2 × 0.8 mm, spreading to recurved at anthesis, the inner surface glabrous except for the minutely papillose tips. Stamens of whorls I and II broadly stipitate, 0.6 mm tall, the anthers broadly ovate, 0.3 × 0.5 mm, glabrous, the apex apiculate, the connectives prolonged between the 2 locelli, these obliquely hemispherical, introrse-latrorse, the filaments laminar, slightly narrower than anthers, glabrous; whorl III stamens columnar, 0.6 mm tall, the anthers ovate, 0.3 × 0.5 mm, erect, locelli 2, extrorse-latrorse, the filaments as broad as anthers, laminar, glabrous, the basal glands sessile, globose, relatively large, filling the space between filaments; whorl IV wanting; pistillode filiform. Pistillate inflorescence with indument, color, and branching as in staminate plants, the flowers similar in size and shape; stamens sterile, smaller; ovary glabrous, ovoid; style slender, distinct from ovary; stigma discoid, 0.3 mm diam. Fruits borne on narrowly claviform pedicels of up to 1.5 × 0.4 cm; cupules infundibuliform, to 1 × 1.5 cm, glabrous inside and outside, the margins entire; drupes ellipsoid, to 2 × 1.4 cm.

Discussion
Endlicheria dysodantha is immediately recognized by its dark-drying subglabrous leaves with barbellate tufts of hairs in the axils of secondary veins below. Close relationship with E. paniculata and allies is suggested by stipitate whorl I and II stamens and pilose indument inside flowers. This has weak molecular support (Fig. 2), but I prefer to place E. dysodantha close to the E. browniana species group. Like other species therein, in E. dysodantha all anthers are ovate with obliquely hemispherical locelli, and slender claviform pedicels support shallowly hemispherical cupules. Its vestiture of extremely short (0.1 mm) appressed hairs is also characteristic of the E. browniana species group.
