Description and Ethnobotany

Growth Form It is a shrub to small tree that can reach up to 8 m in height. Young vegetative parts are covered in fine, appressed, silky hairs.
Foliage The leaves are ovately-elliptic (egg-shaped), papery, measuring 1.2 - 9 cm long by 0.8 - 3.4 cm wide. Both surface of the leaves are covered in fine, appressed, silky hairs while the top surface tend to be less conspicuous. Leaves have a greyish underside with veins flat above, prominent below, leaf bases are somewhat asymmetrical, faintly notched to box-shaped.
Flowers Flowers are monoecious, borne on an inflorescence along the axils, holding both male and female flowers within the same cluster. Flowers are whitish, male flowers tend to be smaller than the female flowers. Male flowers measures at 1.2 - 5 mm wide while the female flowers measures 3.3 - 3.5 mm wide.
Fruit The fruit is a round, flattened, green capsule covered in white velvety hairs, measuiring 6.2 - 7 mm long, 3.3 - 3.5 mm wide. Upon maturity, it spilts from the base of the fruit to reveal bright red, half-moon shaped seeds within.
Habitat Occurs in evergreen forest, common along edges of woods and thickets, on granitic rocks, 50 - 200 m altitude.
Similar G. sericeum and G. obscurum are similar in appearance. They can differentiated by the leaf base, number of veins and fruit morphology. G. sericeum has a mildly asymmetrical leaf base, bear 7 - 11 pairs of lateral veins and produce smaller fruit that are <5 mm wide, borne close to the axils while G. obscurum has a distinctive asymmetrical leaf base, bear 4 - 8 lateral veins on the smaller side of the blade and produce larger fruit that are >10 mm wide, borne on a longer stalk.
Cultivation It can be propagated by seeds
Etymology The genus, Glochidion refers to Glochid which meant 'Spine' in references to the staminal column of the male flowers. The species epipthet, sericeum, in latin, sericeus refers to the indumentum found on various parts of the plant. <1 ,2>
