[Wikipedia] Hybridization, Etymology: It is a very complex species which easily hybridizes, resulting in numerous hybrids and cultivars brought into horticulture since the 1990s. The specific epithet microphylla, from the Greek, means "small leaved". In Mexico it is called mirto de montes, or "myrtle of the mountains".[2] (link added by Mary Ann Machi)
