what does Nymphaea and Bupleurum have in common?
Bupleurum Bupleurum is a large genus of annual or perennial herbs or woody shrubs, with about one hundred and ninety species, belonging to the Apiaceae family. The full size of its species may vary between a few cm to up to 3 m high. Their compound umbels of small flowers are adorned with bracteoles that are sometimes large and may play a role in attracting pollinators. Rare among Apiaceae are the simple leaves, bracts (if present) and bracteoles. The genus is almost exclusively native in the Old World Northern Hemisphere, with one species native to North America and one species native to southern Africa.
Exoporia The Exoporia are a group of primitive Lepidoptera comprising the superfamilies Mnesarchaeoidea and Hepialoidea. They are a natural group or clade which is the sister group of the lepidopteran infraorder Heteroneura. They are characterised by their unique female reproductive system which has an external groove between the ostium bursae and the ovipore by which the sperm is transferred to the egg rather than having the mating and egg-laying parts of the abdomen with a common opening (cloaca) as in other nonditrysian moths, or with separate openings linked internally by a "ductus seminalis" as in the Ditrysia. See Kristensen (1999: 57) for other exoporian characteristics.
