Notes

Araliads with pinnate leaves and an articulated pedicel are here regarded as forming one genus, divided into several sections. These sections have formerly been segregated as genera, but I follow Bernardi, l.c., in uniting them. The most distinctive is sect. Polyscias, characterized by an elongated leaf- sheath. Several of the species of this section are cultivated and have a number of cultivars.
