Elaeocarpus miegei is a tall tree to 35 m, to 20 m in the N.T. occasionally reported to have buttresses at the base of the trunk. Indumentum is of fine appressed hairs on young stems and petioles or glabrous. Petiole 10-30 mm. Lamina oblanceolate, obovate to elliptic, 40-170 mm long, 20-75 mm wide; base cuneate, margin crenate-dentate, apex obtuse, rounded or acute; glabrous or with few appressed hairs beneath; discolorous, domatia rare or absent. Inflorescence borne amongst or behind the leaves, racemose, to 100 mm long, minutely hairy or glabrous. Bracts caducous. Pedicel to 10 mm long. Sepals 4 or 5, 4.5-5 mm long, 0.5-1 mm wide, sparsely pubescent or glabrous. Petals 4 or 5, obovate or oblong-obovate, c. 5 mm long, 1.5-2.5 mm wide, white/cream; glabrous, apex variously divided. Disk hairy. Stamens 8 -15, between disk and ovary, c. 2-3 mm long (hairiness not known), anther connective sharply pointed. Ovary glabrous or rarely hairy; style tapered, 2-3 mm long, glabrous. Fruit ellipsoid, c. 17 mm long, c. 12 mm diam., glabrous, bright blue. Stone probably smooth, slightly winged.

Australian Government, Conservation Advice, Elaeocarpus miegei
These species are listed as a Key Threatening Process under the EPBC Act The entire Australian population of E. (DEWHA; 2009) because they modify miegei is under current and potential landscape fire regimes to the detriment of threat from encroachment by invasive biodiversity.
High in fire intensity miegei faces potential threat from disturbance by changed fire regimes.
Reduced groundwater discharge to the wet rainforests in which E. miegei occurs may result in a) the direct mortality of established individuals through a reduction in the hydroperiod required to support the species b) reproductive failure of individuals and lack of recruitment to the population due to ecological stress or unsuitable conditions for seed germination and establishment and c) increased susceptibility of the preferred habitat to potential impacts from other plausible threatening processes (fire regime and invasive weedy grasses) as a result of a progressively drying habitat.

These species pose a serious threat by increasing fuel loads; leading to increased fire intensity (Rossiter et al.; 2003); extensive changes in the community structure and critical changes in soil chemistry and potential degradation of rainforest habitat (Panton; 1993).
