While there are no commonly used synonyms for this specific genus, there are numerous related genera within the same family, including Pyrus (pear), Malus (apple), and Sorbus (mountain ash). These genera share many similar characteristics and are often grouped together by botanists and horticulturists. Species within the Pygopus genus are known for their showy flowers, colorful foliage, and in some cases, edible fruit. These woody plants are a popular choice for home gardens, parks, and urban landscaping projects.
