Three forms may be recognized: f. helenae, which has singly serrate, abaxially eglandular leaflets; f. duplicata T. C. Ku (Bull. Bot. Res., Harbin 10(1): 12. 1990), which has doubly serrate, abaxially eglandular leaflets; and f. glandulifera T. C. Ku (Bull. Bot. Res., Harbin 10(1): 12. 1990), which has singly serrate, abaxially glandular leaflets.
