Zigadenus elegans

Flower Longitudinal Section

Note that the petals are not attached to the bottom of the ovary, but rather at about two thirds of the way to the top.  Thus the ovary is partially inferior, unlike that of Z. venenosus which is superior.  Note also the obcordate (inverted-heart-shaped), green glands near the bases of the tepals.
