Polyscias fruticosa

Description

Glabrous shrub or, small tree, up to 5 m, with branches bearing spirally arranged leaves towards their ends. Leaves tripinnate, variable in size to c. 75 cm long; Inflorescence a diffuse panicle; Petals 5, 2 mm long. Stamens 5. Ovary turbinate, c. 1 mm high, 2-3(-4)-celled; Fruit subglobose, fleshy, c. 5 mm ø when dry.

Distribution

other parts of the Indo-Pacific tropics present
Native country not properly known, cultivated throughout the region, and in other parts of the Indo-Pacific tropics.

Notes

The foliage of this plant is extremely variable in size and form. Typical plants are figured by Koorders (1916, l.c.) and by Ochse & Bakhuizen van den Brink (l.c.). These may be readily identified by the intricately compound leaf.
The individual leaflets are characteristically ovate-lanceolate and serrate to deeply pinnatifid. However, broader leaflets with simpler outlines are not uncommon. The more rotund, blunter leaflets of P. obtusa are considered here to be an extreme form of this species (the type is bipinnate).
Occasional specimens have leaves so much reduced that they are simply pinnate or unifoliolate when they approach forms of 6. P. cumingiana.
A number of names have been applied to horticultural forms belonging to this section of the genus (cf. ), but the interrelations of these will be understood only after intensive biosystematic study of the many cultivars.
