A lofty tree up to 130 ft. high, never seen to throw out aërial roots (Welwitsch); trunk always straight, moderately thick; head dense, ovoid-oblong; branches suberect, repeatedly divided; young leafy shoots mostly softly tomentose but sometimes quite glabrous and always becoming so when mature. Leaves ovate or ovate-elliptic, long and acutely caudate-acuminate, cordate or rounded at the base, 2 1/2–6 1/2 in. long, 1 1/2–3 1/4 in. broad, entire, rigidly chartaceous or rarely submembranous, glabrous and closely reticulate on both surfaces, sometimes slightly shining, often finely punctate on the lower surface; midrib slightly more prominent below than above, glabrous; lateral nerves about 10 on each side, arising from the midrib at an angle of about 65°, looped well within the margin, like the veins prominent on both surfaces; petiole 1 1/4–2 1/2 in. long, slender, subterete, glabrous; stipules very caducous, linear, acute, 1 1/2–2 in. long on the newly opened shoots, membranous, pubescent outside on the lower part. Receptacles axillary, sessile, solitary or in pairs, subglobose, obtusely mammillate at the apex, 3–4 lin. in diam., thinly pubescent or nearly glabrous when ripe. Basal bracts 3, imbricate, broadly ovate, rounded at the apex, about 1 1/2 lin. long and broad, coriaceous, finely and rather thinly pubescent outside, glabrous within. Outer ostiolar bracts about 3, imbricate, spreading horizontally over the mouth of the ostiole, suborbicular, the remainder also spreading horizontally, ovate or oblong-ovate, rounded or truncate at the apex, membranous. Male flowers several, near the ostiole, subsessile; perianth-segments 4, obovate-elliptic, rounded at the apex, 1/2 lin. long, membranous; stamen solitary; filament 1/2 lin. long; anther 1/4 lin. long. Gall flowers numerous, scattered amongst the female, pedicellate; perianth-segments 4–5, oblanceolate, subacute, membranous. Female flowers sessile: perianth more or less as in the gall flowers; style lateral, subpersistent.
