Examples

“The Jubulaceae have⟳ a leaf whose lobule, usually transformed into a water-sac, is normally very narrowly attached to the stem and to the dorsal lobe; indeed some Frullania taxa reproduce⟳ vegetatively by dropping the dorsal lobes, but not the lobules, and Neohattoria has caducous lobules but persistent lobes.”
