Cannabaceae

Palmately compound or simple leaves on herbs and trees; tiny, wind-pollinated, unisexual flowers on separate male and female plants cluster into loose panicles or tight cone-like spikes, without showy petals.

Female flower clusters in Cannabis are coated in resin-secreting glandular hairs that produce the plant's psychoactive and aromatic compounds, while unrelated genera in this family instead just yield a small dry hackberry-type fruit.
