Botanical Description

C. pani­culatus comes from the family of Celastraceae. It is a climbing, deciduous, usually dioecious shrub that can reach up to 10 m tall. [4]

The stem can grows up to 25 cm in diametre, with cylindrical branchlets and hairy. [4]

The leaves are arranged spirally, simple, elliptical to suborbicu­lar to oblong, measure 5-15 cm x 2.5-6 cm, with wedge-shaped base, obtuse or rounded, acute at apex, acuminate, obtuse, rarely notched at the extremity, with remotely crenulate margin, elevated midrib and smooth. The petiole is 0.5-1.5 cm long with small stipules. [4]

The inflorescence is an axillary or panicle termi­nal, usually thrice to multi-compound, spreading, (2-)5-10(-20) cm long and with 0.6-1 cm long peduncle. Its flowers are unisexual, 5-merous, pale green­ish, with 1.5-3.5 mm long pedicel, accrescent to 3-6 mm and articulate at the base. The sepal is bell-shaped, per­sistent, with semi-orbicular lobes, short-ciliate and it measures about 1 mm x 1.5 mm. The petals are oblong to obovate-oblong, ob­tuse, entire, and measure 2.5-3 mm x 1-1.5 mm. The disk is cupular and obscurely 5-lobed. [4]

The male flower have stamens of about 3 mm long, with columnar pistil and about 1 mm long while in the fe­male flowers, staminodes are about 1 mm long, with 2-2.5 mm long pistil, superior ovary, spherical, (in)completely 3-celled, ovules 1-2 per cell, with colum­nar style and 3-lobed stigma. [4]

The fruit is a nearly spherical capsule, 3-valved loculicidally with broad-elliptical valves, measuring 5-10 mm x 5-8 mm and 3-6-seeded. The seed is ellipsoid, measures 3.5-5 mm x 2-3 mm, enveloped by a fleshy orange to crimson aril, yellowish to reddish brown, smooth or with obscure areoles. The albumen is copious, with thin cotyle­dons and broadly spathulate. [4]

The seedling is with epigeal germination. [4]
