Caesalpinia rostrata

Family : Caesalpiniaceae (Bauhinia family)
Common names : beakpod plumeflower/ beaked plumeflower (Eng.); tuitpeulpronkstert (Afr.)


This medium to large scrambling shrub with its beautiful leaf patterns produces pink flowers towards the end of the year. It is an interesting plant for gardeners in frost free areas looking for something different.

Caesalpinia rostrata is a large, scrambling woody shrub that grows up to 3 metres and can on occasion form dense thickets. The main stem is armed with hooked thorns that can reach up to 10 mm. The leaves are twice-compound with small leaflets and an asymmetrical base and rounded tips. The petiole (leaf stalk) is 6 – 15 mm long.

The pink flowers are produced from November to January in terminal or axillary racemes. The fruits, produced from January to February, are short, inflated pods of about 27–32 mm length. The pods are tipped with a characteristic beak.

Conservation status
According to the Red List of South African Plants Caesalpinia rostrata is categorized as Vulnerable ( VU ). This means that “the best available evidence indicates that it meets at least one of the five IUCN criteria for Vulnerable, indicating that the species is facing a high risk of extinction. ” Habitat loss to sugarcane cultivation seems to be the main threat.

Distribution and habitat
Caesalpinia rostrata grows in Bushveld, often along river valleys and drainage lines in isolated localities in southern Mozambique and eastern parts of Mpumalanga.

Derivation of name and historical aspects
The genus name Caesalpinia was given in commemoration of botanist and physician A. Caesalpinius, who died in 1603.

The specific name rostrata means beaked and refers to the seedpods.

The nectar-rich flowers attract bees and other insects.

Uses and cultural aspects
No traditional uses reported. Even though this isn't a plant commonly found in nurseries if you are able to source it, it makes for a good garden subject with its pink flowers and with its tendency to form thickets it can be used as a hedge or barrier plant in areas where it is evergreen.
