1. The utricle is the main detector that responds when you’re riding in a car and suddenly accelerate.

2. The utricle and the saccule, on the other hand, detect linear acceleration; they are therefore called the gravity sensors.

3. Fruits drupes or samaras (rarely syncarps, utricles, or Baccates), fleshy or dry, occasionally subtended by a fleshy hypocarp or an accrescent, chartaceous or fleshy calyx or corolla; mesocarp sometimes with prominent black resin canals.

4. Fruits drupes or samaras (rarely syncarps, utricles, nut -like, or Baccates), fleshy or dry, occasionally subtended by a fleshy hypocarp or an accrescent , chartaceous or fleshy calyx ; mesocarp sometimes with prominent black resin canals.

5. The fruits are drupes or samaras (rarely syncarps, utricles, or Baccates), and all appear to be derived from a fundamentally drupaceous fruit type as elucidated in the family phylogeny (see Taxonomy and Phylogeny section for more detail)
