Salix sepulcralis group Salix sepulcralis group The "Salix sepulcralis" group is a cultivar group containing all cultivars of hybrids between "Salix alba" and "Salix babylonica". The "sepulcralis" or × "sepulcralis" trees are sometimes referred to as white weeping willow or glaucous weeping willow in reference to the mixed appearance from the parent species. It was first described by L. Simonkai in 1890 from trees growing in Romania. The group contains both weeping and nonweeping cultivars, though the best-known of its cultivars is 'Chrysocoma', the most widely grown weeping tree.. Some of the cultivars are hybrids of "S. babylonica" var. "matsudana" 'Tortuosa' and have
Salix triandra other willows having two or five stamens. The scientific name derives from the male flowers having three stamens. The English common name refers to the similarity in leaf shape to almond leaves. The variety "Salix triandra" var. "hoffmanniana" Bab., found in Great Britain, is distinguished by being smaller (rarely over tall) and densely branched, with smaller leaves 2–7 cm long and 1-2.5 cm wide not glaucous below. It is not considered distinct by all authorities, particularly on continental Europe, so its range outside Britain, if any, is not reported. "Salix triandra" readily forms natural hybrids with "Salix viminalis", the hybrid
