About Cyrilla racemiflora L.
Cyrilla racemiflora L. grows as a large tree in tropical rainforests, reaching 15 metres (49 ft) or more in height and over 1 metre (3 ft 3 in) in trunk diameter. At the northern edge of its range in temperate regions, it only grows as a shrub reaching 4 metres (13 ft) in height. It is most easily recognized by its white flowers, which are prominent on the plant during the summer. It is primarily evergreen, but in autumn some leaves turn a brilliant red before falling. Plants growing at the northern edge of its range are usually deciduous. Its leaves are alternate, simple, and range from oblanceolate to oval in shape. They are rounded or pointed at the tip, narrowed toward the base, thick, toothless, and smooth, with reticulate venation. Leaves measure 4โ10 centimetres (2โ4 in) long and 1.2โ3 centimetres (15โ32โ1+3โ16 in) broad. The flowers are tightly clustered in 8โ15 centimetre (3โ6 in) long racemes that grow on twigs from the previous year. Each flower is 5โ10 millimetres (3โ16โ13โ32 in) in diameter, has five white petals, and is subtended by a slender bract. The fruit is a yellow-brown capsule 2โ3 millimetres (5โ64โ15โ128 in) long. Large individuals have thin, reddish-brown bark that is often shaggy in appearance, while smaller individuals have gray to brown bark that is mostly smooth with light fissuring. This species can be found in rainforests, swamps, along streams, bogs, bayheads, backwaters, wet prairies, low pinelands, pocosins, and flatwood depressions. It prefers acidic, sandy, or peaty soils.
