Flower of LYC 1831, Solanum pennellii. Rather than having an "anther cone" , it has an "anther cylinder". The anthers are not fully joined together. The ends of the cylinder are open so that pollen can easily leave. The stigma is exerted. The flowers are located on an inflorescence high above the foliage. Just the kind of thing that I am looking for to contribute to a promiscuous pollination project.
