Later, in the United Kingdom, Bentham and Hooker published their volume on the Liliaceae in Latin in 1883. They divided the family into 20 tribes and placed "Ornithogalum" in the tribe Scilleae with 19 other genera, and indicated 70 species existed. In the German literature the taxonomic system of Engler completed its classification of the Liliaceae in 1888. He divided the family into 12 subfamilies and subordinate tribes. "Ornithogalum" was then placed in the subfamily Lilioideae and tribe Scilleae together with 21 other genera. The 70 species of "Ornithogalum" were then further divided into six sections, with section "Heliocharmos" corresponding to Baker's subgenus.
