Yucatan Daisy (Montanoa atriplicifolia) is a woody shrub that acts like a vine as it sprawls over other plants. Maybe it is a vine that tends to be somewhat shrublike. It seems to be one of those plants that is somewhere in the middle, neither shrub nor vine. It is native to southern Mexico and most of Central America. A fall/winter bloomer in South Florida with massive amounts of white showy daisy looking flowers. It is an excellent pollen source for honey bees. This plant is not commonly found in landscapes, but maybe it should be when you see the flowers this time of year.
Richard Lyons Nursery currently has this plant in stock and it is in full bloom.
