Me too. It’s easy to predict what the corresponding chart will look like on the taxon page ;-)
The fact that the “Sex” annotation can be applied to bisexual plants is a potential source of confusion and/or bugs. For example, if a user erroneously applies the “Sex” annotation to a bisexual plant, a “Sex” chart is automatically displayed on the taxon page. Even if the annotation is downvoted, the chart is still displayed on the taxon page. It would be better if the “Sex” annotation were removed from the interface in the case of bisexual plants.
