## Habitat

Can be found in rainforests, swamps, along streams, bogs, bayheads, backwaters, wet prairies, low pinelands, pocosins, flatwood depressions, preferring acidic, sandy, or peaty soils.

## Description

In tropical rainforests, it is a large tree growing to 15 metres (49 ft) or more tall and greater than 1 metre (3 ft 3 in) in diameter, but only a shrub to 4 metres (13 ft) tall in temperate regions at the northern edge of its range. It is most recognizable from its white flowers which are noticeable on the plant during the summer months. It is primarily evergreen, but during the autumn months some of the leaves turn a brilliant red before falling, and plants at the northern edge of its range tend to be deciduous. The leaves are alternate, simple, oblanceolate to oval, rounded or pointed at the tip, narrowed to the base, thick, without teeth, smooth, sometimes nearly evergreen, reticulate-veined, 4–10 centimetres (2–4 in) long and 1.2–3 centimetres (15⁄32–1 3⁄16 in) broad. The flowers are crowded in 8–15 centimetres (3–6 in) long racemes borne on the previous year's twigs; each flower is 5–10 millimetres (3⁄16–13⁄32 in) diameter, with five white petals, and is subtended by a slender bract. The fruit is a yellow-brown capsule 2–3 millimetres (5⁄64–15⁄128 in) long. The bark of large individuals is a reddish-brown colored thin bark often shaggy in appearance. The bark of smaller individuals is gray to brown, smoothish and lightly fissured.

## Taxonomy

Although generally treated as a single variable species, some botanists in the past have split Cyrilla racemiflora into several species. Synonyms include C. antillana, C. arida, C. brevifolia, C. caroliniana, C. cubensis, C. fuscata, C. nipensis, C. nitidissima, C. parvifolia, C. perrottetii, C. polystachia.[citation needed]
