Geographical Distributions

Clausena sanki is endemic to the Philippines and Borneo. In the Philippines, it is distributed all over the archipelago. [2]

C. sanki grows naturally in the understorey of rainforests, on various soil types (including limestone) and up to 1500 m altitude. [2]

Botanical Description

C. sanki falls under the family of Rutaceae. It is an evergreen shrub or small tree that can reach up to 2-6(-15) m tall and bears some essential-oil glands on all aerial parts which emit a strong anise or anise-like smell when crushed. [2]

The leaves are arranged alternately, imparipinnately compound, measure 20-55(-100) cm long and hairless to hairy. The petiolules are 1-5 mm long. The leaflets are 7-13(-19), alternate to subopposite, ovate to lance-shaped, measuring 3-25 cm x 1-10 cm where the largest ones is near the apex, oblique at the base, undulate-crenulate at the margin, acute-acuminate at the apex and densely dotted with pellucid glands. [2]

The inflorescence is a terminal (rarely axillary) measures 6-40 cm long and with a conical panicle. The pedicel measures up to 2 mm long. [2]

The flowers are spherical in bud measuring 6-8 mm in diametre when opened, regular, with 5-merous and fragrant. The green sepal is 5-lobed measures 0.5-1 mm long. There are 5 free petals, which are ovate-elliptical, measure 4-5 mm long, with membranaceous and whitish-green. There are 10 free stamens where the filaments are geniculate, with white and yellow anthers. The ovary is spherical to somewhat pentagonal, measures about 1 mm long and wide; with 5-locular, born on gynophore is 0.3-0.5 mm long, with the style is 1 mm long and the stigma is slightly 5-lobed. [2]

The fruit is a berry with 1(-3)-seeded, slightly spherical (rarely ovoid), measuring 0.8-1.6 cm in diametre and whitish-green but turns pinkish at maturity. [2]

The seed is green. [2]


C. sanki is sporadically cultivated in gardens in China, Taiwan, Vietnam and Indonesia. In cultivation in Indonesia, it only performed well up to 500 m altitude. In Solok (west-central Sumatra), it grows well in 2000 mm annual rainfall maximum in March and November and a minimum of about 75 mm per month from June to August, with maximum temperatures of about 30°C and minima of about 20°C throughout the year, and on poor, acid (pH 4.0-4.2) soils.
