Are Sinningia and Hyoscyamus in the same family?
Hyoscyamus Hyoscyamus — known as the henbanes — is a small genus of flowering plants in the nightshade family, Solanaceae. It comprises 11 species, all of which are toxic. It, along with other genera in the same family, is a source of the drug hyoscyamine (daturine).
Psalmopoeus Psalmopoeus is a genus of the family "Theraphosidae" containing various species of tarantulas. The genus is native to Central America and South America including the West Indies. These species are believed to be relatively venomous, and research in the venom of "P. cambridgei" shows it to be similar to capsaicin, the molecule causing irritation in chili peppers. These molecules activate sensory cells to send pain signals to the brain. Genetic engineers are working on blocking the receptors that are activated by these molecules.
