- Observation Flower, foliage and reproduction biomass differed significantly among individuals.
- Observation Mean female flower biomass was 1.84 times male flower biomass.
- Observation Mean female reproduction biomass was 16 times male reproduction biomass.
- Observation Male foliage biomass exceeded female foliage biomass without a significant difference.
- Observation Shrub flower and reproductive biomass and diameter increment differed significantly by sex.
- Observation Shrub foliage biomass did not differ significantly by sex.
- Association DBH size correlated positively with flower and reproductive and foliage biomass and diameter increment.
- Observation Female shrub flower biomass was 1.6 times male biomass.
- Observation Female shrub reproductive biomass was 1.93 times male biomass.
- Observation Female shrub foliage biomass was 1.1 times male biomass.
- Observation Males began flowering earlier than females, on 25 May versus 28 May.
- Observation Females began fruiting on 8 June.
- Observation The plot contained 310 female, 53 male and 225 non-reproductive trees in 2010.
- Observation The population sex ratio of 0.17 significantly deviated from 1:1.
- Observation The 0–2, 2–4, 4–6 and 6–8 cm DBH classes had female-biased sex ratios.
