The white-petaled flower shown here, supposedly of Ilex mucronata, and the 2nd image, showing a flowering shrub of the same species, are actually images of an Amelanchier (Rosaceae) and nothing like the unisexual, very small, flowers of Ilex mucronata (Aquifoliaceae). For an accurate image of Ilex mucronata flowers (male), see:
