Catunaregam taylorii (S.Moore) Bridson

Shrub or tree 2-6 m tall with branches spreading and often trailing; young stems densely pubescent tomentose, lenticellate; older stems usually unbranched, but sometimes with straight spiny lateral branches; bark dark grey, dark brown or reddish-brown, flaky; spines borne above cushion shoots or brachyblasts, mostly paired, infrequently a few alternate, or absent at lower nodes, usually exceeding the brachyblasts (at least when flowering), very occasionally developing into fertile branches; cushion shoots eventually lengthening to become brachyblasts, up to 2.5 cm long (or rarely 5 cm in fruit), occasionally developing into fertile shoots, usually unbranched but rarely with short branches. Leaves always very immature at time of flowering, 3-10 x 1.2-5.3 cm, obovate, rounded at apex, tapered at base, densely pubescent when young, when mature pubescent with nerves densely so beneath and sparsely pubescent above; lateral nerves in (5)6-8 main pairs; tertiary nerves coarsely reticulate not conspicuous; petiole 2-6(10) mm long; stipules on young stems 4-6 mm long, triangular-apiculate. Flowers scented, ?hermaphrodite, variable, 1-2(3); peduncle not apparent; pedicels 2-4(7) mm long, densely pubescent; bracts absent. Calyx densely velvety pubescent; tube 2-5 mm long; limb-tube 2-5 mm long; lobes 1.5-6 mm long, either variable in number and unequal, linear, oblong or obovate, sometimes almost entirely reduced (?perhaps not developing until the flowers mature), or with 4-5 ± equal, broadly ovate, 1-or 3-nerved, sometimes with a rudimentary lobe present in sinuses between lobes. Corolla white maturing to yellow; tube ± equal to or slightly exceeding calyx limb-tube; lobes 4-5, 6-15 mm long, ovate or almost circular, puberulous towards margin above. Anthers c. 3 mm long; style projecting from the corolla throat by 1-2 mm; pollen presenter c. 2-3 mm long. Fruit 1.4-2.5 x 1.1-2.3 cm, almost spherical or broadly ellipsoid, with 8-10 ribs apparent, pubescent; calyx limb persistent mostly with 4-5 broadly ovate slightly accrescent lobes up to 6 mm long, but occasionally with several linear or oblong ones; stalk 4-10 mm long.
