According to several sites on the internet..."That little pepper inside a bigger pepper is called an 'internal proliferation.' Its form can vary from irregular and contorted to a near-perfect but sterile fruit. A pepper growing inside a pepper is a type of parthenocarpy, which is the formation of fruits without fertilization or the formation of seeds."
