Hyacinthoides × massartiana

Hyacinthoides × massartiana has become widespread across Britain and Belgium,^[2] both of which have large populations of H. non-scripta. It is often found on the edges of woodland and roadsides, particularly in urban areas, suggesting that it has spread from gardens planted with H. hispanica.^[3] There is great concern over the effect that the hybrid may have on native H. non-scripta populations, diluting the characteristics of the native species and out-competing it due to H. hispanica's robust fertility and the effects of climate change.^[4]

Hybrids between H. non-scripta and H. hispanica were first given a specific name in 1997, when the Belgian botanist D. Geerinck described them as H. × massartiana,^[5] honouring the botanist Jean Massart.^[6] The type locality is Watermael-Boitsfort, near Brussels, Belgium; the holotype is held in Brussels, with an isotype in Liège.^[7] The same taxon had already been given the name "Hyacinthoides × variabilis" by P. D. Sell in 1996 in the Flora of Great Britain and Ireland,^[8] but without a valid Latin diagnosis.^[6]
