The nomenclature of Acis trichophylla is somewhat complex. The epithet trichophyllum was first published, in the combination Leucojum trichophyllum, by Peter Schousboe in 1800.[6][7] The combination was used again as a supposedly new name by Félix Brotero in 1804,[8] but as it had already been published in 1800, Leucojum trichophyllum Brot. is an illegitimate later homonym.[1] In 1829, Robert Sweet suggested that Leucojum trichophyllum belonged in Acis, but did not explicitly use the combination Acis trichophylla nor make clear whose Leucojum name he meant.[9] The combination Acis trichophylla was first used in 1830 by George Don, referring to Sweet (he actually used the masculine form trichophyllus).[10]
