Description
Species Description - Trees to 15 m. Branchlets stout, midway along flush 4-6 mm diam., distally weakly angular, soon terete, densely rusty to reddish tomentose, the surface concealed by the indument cover, the hairs relatively long, to 0.6, straight to crisped, erect to ascending; terminal buds plump, 2 × 2 mm, densely pubescent, the hairs rusty to red, ascending. Leaves alternate, widely and evenly spaced along current flush; petioles slender, to 2.5 × 0.3 cm, semi-terete, the indument as on branchlets; laminae coriaceous to chartaceous, plane to subbullate, ovate to elliptic, 9-25 × 4-10 cm, the base acute to rounded, briefly decurrent, the apex acute to obtuse, acuminate for up to 2.5 cm, the margins minutely recurved throughout; upper surface dull greyish green to olive-brown, minutely punctulate, the primary to fourth-order veins raised, their prominence decreasing with rank, or tertiary and higher-order veins immersed; lower surface densely pilose, the hairs soft, erect, up to 1 mm long, rust brown, slightly shorter and denser on main veins, all vein orders raised, their prominence decreasing with rank; secondary veins 4-6 per side, ± evenly spaced, slightly more distant around midlamina, ascending at 50-60° (more obtuse around midlamina), arcuate, distal pairs loop-connected; tertiaries roughly horizontal, between secondaries straight, or forked. Staminate inflorescences evenly spaced along current flush in the axils of foliage leaves or cataphylls, to 25 cm long with 14 lateral branches, branch orders 3-4, the highest order dichasial, lax, the flowers distant, the axes densely rusty tomentose; bracts and bracteoles caducous by anthesis, narrow ovate to lanceolate, the indument as on axes; pedicels terete, to 2 mm long, those supporting secondary flowers slightly shorter. Flowers depressed-globose to urceolate, 1.5 to 3 mm diam., sparsely rusty to grey-strigose outside; receptacle deeply cyathiform, 1 × 2, densely rusty red velutinous inside. Tepals chartaceous, broadly ovate, 1 × 1.5 mm (the inner whorl slightly narrower), incurved to erect at anthesis, the inner surface minutely papillose. Stamens of whorls I and II broadly stipitate, 0.6-1 mm tall, the anthers ovate, 0.3-0.5 × 0.3-0.6 mm, glabrous, the apex apiculate, the connectives prolonged between the 2 locelli, these obliquely hemispherical, introrse-latrorse, the filaments ligulate, almost as broad as anthers, densely grey-tomentose; whorl III stamens sessile, 0.6-1 mm tall, the anthers depressed-oblong, 0.2-0.3 × 0.3-0.5 mm, erect, locelli 2, extrorse-latrorse, the filaments as broad as anthers, wider towards base, the indument as in outer whorls, the basal glands sessile, globose; 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 minutely tri-lobed, ca. 0.2 mm diam., emerging beyond incurved tepals. Fruits borne on short claviform pedicels of up to 5 × 5 mm; cupules hemispherical, to 0.5 × 1 cm, glabrous inside and outside, the margins undulate, tepal bases persisting; drupes ellipsoid to obovoid, to 1.5 × 1 cm.

Discussion
Endlicheria szyszylowiczii is readily distinguished from other species with dense reddish tomentose branchlets by its depressed-globose to campanulate flowers with tepals incurved to erect at anthesis. In vegetatively similar species, ascending tepals may yield infundibuliform flowers, but horizontally spreading tepals predominate. At first glance the higher-elevation material of E. szyszylowiczii (e.g., van der Werff et al 8340) may be mistaken for E. duotincta because the pale lower leaf surface contrasting with the erect reddish hairs produce an aspect similar to that bestowed by the mixed indument of the latter. Despite a wide geographic and altitudinal range, the only noteworthy internal variation appears as slightly reduced floral size and paler pubescence in extra-Andean collections.

Distribution
Mediumsized trees ranging throughout the Amazonian lowlands and reaching the surrounding highlands of the Guiana shield to the north, the Brazilian shield to the south, and lower montane Andes to the west at 200-2200 m. Flowering material collected from February through November, fruits in July, and September through November.
