Are Sinningia and Hyoscyamus in the same family?
Sinningia Sinningia is a genus of flowering plants in the family Gesneriaceae. It is named after Wilhelm Sinning (1792-1874), a gardener of the Botanische Gärten der Friedrich-Wilhelms-Universität Bonn. There are about 65 species of tuberous herbaceous perennials, all occurring in Central and South America, with the greatest concentration of species occurring in southern Brazil.
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.
