Other claims from this paper (9)
- Observation More than 80% of female Cycas trees were unbranched with a single stem.
- Observation More than 80% of male Cycas trees exhibited two or more branches.
- Association Male plants had a mean number of branches more than double that of female plants in Cycas.
- Association Zamia plants produced 2.8-fold greater numbers of branches than the mean of the Cycas plants.
- Observation Unsexed C. micronesica trees on Guam were unbranched in 2004.
- Observation After 15 years of herbivore damage, most remaining live C. micronesica trees in 2020 had three or more branches.
- Association Non-native insect herbivores selectively killed more female C. micronesica trees.
- Association Cycad species with determinate female strobili may produce more branches on female plants than species with indeterminate female strobili.
- Recommendation Horticulture and conservation decisions may be improved by knowledge of sexual dimorphism in cycad branching.
