Systematics of Aral'ia 15 Inflorescence The presence or absence of a main inflorescence axis was in the past considered to be important taxonomically in Aralia (Harms 1896; Hoo and Tseng 1965). Harms (1896) used this character to distinguish two sections: sect. Genuinae (= sect. Aralia) with a well-developed main axis, and sect. Anomalae without a main axis. Hoo and Tseng (1965) employed this character to differentiate sect. Arborescentes Harms (synonymous with sect. Dimorphanthus, characterized by having a main axis) from sect

Digitatipanicula Hoo (without a main axis). In contrast to Harms (1896) and Hoo and Tseng (1965), I regard the presence or absence of a main inflorescence axis as significant only at the species level, and so it is not used here to delimit sections (also see Wen 2004). Several species (, Aralia fargesii) show an intermediate inflorescence. Fig. 4. Epidermal characters of Aralia apioides: A-C. Trichomes on pedicels. D. Trichome on lower leaflet surface. E. Trichome on upper leaflet surface. F. Stomates on lower leaflet surface {Wen et al. 1241, US)..
