== Description ==
Silky camellia is an understory woodland species with rich brown bark. The young stems are hairy. The branches tend to grow with a horizontal orientation from the main stem with the foliage produced on shorter stems branching off these horizontally oriented branches.〔(Trees, Shrubs, and Woody Vines of North Carolina: Silky-Camellia (''Stewartia malacodendron'') )〕 The alternately arranged, dark green, simple leaves are 50 to 100 mm long (2 to 4 inches) with finely toothed margins covered with fine hairs on the undersides, especially on the veins. The leaves are ovate to elliptical in shape with sharp pointed tips. The buds are covered by two floral bracts with silvery hairs. The flowers are 60–90 mm wide(2.5 to 3.5 inches),〔(Trees: Stewartia malacodendron )〕 showy, with five white petals. The stamens have purple filaments and blue anthers that fill the middle of flat, cup shaped corollas. The flowers are born singly from the leaf axils on short stalks with two floral bracts (2–4 mm long) that remain after flowering. Flowers have five green sepals, 8–11 mm long and 5–9 mm wide. Blooming in July and August in the northern part of its range and in April in the southern part of its range.〔DIRR, M. (1983).

ISBN 0-87563-226-2〕 Rounded, woody seed capsules are produced after flowering, each capsule with 4-5 chambers, and if fertilized, each chamber has 2-4 seeds.〔http://georgiawildlife.dnr.state.ga.us/assets/documents/stewma.pdf〕 The shiny, wingless seeds are full, ovoid in shape and purplish to reddish-brown in color; each seed is 5–7 mm long and 4–6 mm wide.
