Morphology General Habit
Tree, up to 5 m tall; trunk greyish, up to c. 15 cm in diam.; crown dense, rounded; branches numerous, erect to ascending, terete, fleshy, up to c. 8 mm in diam., greyish-green, with a thick waxy coating, papillate to shortly hairy when young
Morphology Leaves
Leaves sessile, fleshy, elliptic to obovate or suborbicular, 1–3 x 1–2 mm, from a persistent cushion-shaped base, obtuse at the apex, papillate to shortly hairy, soon deciduous; glandular stipules obsolete

Cyathia solitary at tips of branchlets, apparently unisexual (only female seen), sessile, c. 3 mm in diam.; bracts rounded, ciliate, unequal, 0.5–1.5 x 0.5–1 mm, brownish, clasping the base of the cyathium; involucre c. 3 mm long and 2 mm wide, cylindrical but slightly broader towards base, glabrous except for hairy base, lobes triangular, c. 0.5 mm long, ciliate; glands 5, quite separate, transversely elliptic, 1.5–1.6 x 0.8–1 mm, entire, dark red
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous; styles 3, c. 2 mm long, joined to about halfway, with recurved and distinctly bifid apices

Conservation
E. spissa is only known from a single population with some 20 trees.
Note
It is probably related to E. bariensis in N3, but differs by being a tree (E. bariensis is a shrub, up to 1 m tall), with solitary (not clustered) cyathia with the involucrum hairy towards the base only (not tomentose throughout), and in its larger capsules (c. 8 mm versus 5–5.5 mm in diam.)
