Chamaecrista lineata and Relatives

This section explores information about Chamaecrista lineata, also known as Narrow-pod Sensitive-pea, and its close relatives like Chamaecrista fasciculata (Partridge Pea) and Chamaecrista nictitans (Wild Sensitive Plant). These plants share similar characteristics and are often grouped together based on their sensitivity to touch and similar morphology.

Considerations for Pets

  • The text mentions "hairy pea pods" in some species, which may be a physical irritant.
  • Seed pods are present.

Considerations for Children

  • The seed pods split open, releasing seeds that may pose a choking hazard.
  • The text mentions "hairy pea pods" in some species, which may be a physical irritant.
  • Leaves of some species are "sensitive," folding together when touched, which may be interesting for children but should be observed to avoid excessive handling.
