Colubrina pedunculata

Colubrina pedunculata is a shrub in the family Rhamnaceae. It is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean. Its specific epithet comes from the Latin pedunculatus, referring to the long and conspicuous peduncle of the inflorescence. [2]

Description

Colubrina pedunculata is a thorny, sometimes straggling, shrub or small tree. Its thorns are 5–20 mm long. Its leaves are alternate, narrowly elliptic, and deciduous after fruiting. It bears many yellow-green flowers, 5–6 mm across and clustered. The fruit is about 7 mm long. [2]

Distribution and habitat

Found only on Christmas Island, the plant is common on the northern and north-eastern terraces, in areas of poor, dry soil, among limestone pinnacles and scree, and in cliff edge thickets. [2]

Relationships

Since it is closely related to the widespread C. asiatica (L.) Brongn., the fruit of which is used as a fish toxin, and the leaves of which are used medicinally to treat skin diseases, similar chemical or pharmacological properties may be expected in C. pedunculata. [2]
