Acer × rotundilobum Schwer.

Modern name

Acer × rotundilobum Schwer.

A hybrid of uncertain origin, although cultivated in Europe for more than half a century. It is probably a cross between A. monspessulanum and A. opalus var. obtusatum, being intermediate in its various characters between those two maples. Leaves three-lobed, sometimes with two additional, indistinct lobes at the base; 21⁄2 to 4 in. long and broad, reddish when young, smooth except for a little down at the base beneath; pale beneath, dark green above; lobes shallow, rounded; leaf-stalk not milky.

Modern name

Some names used by Bean have now been superseded and are no longer familiar. To ensure that all plants can be easily found, under any name, we have cross-referenced to The Plant List, a collaboration between RBG Kew, Missouri Botanical Gardens and other organisations, which aims to provide a currently accepted name for any plant. Not all taxonomists will agree with all Plant List nomenclature, but it provides a baseline to compare names. For each species above, clicking on the Modern Name will link to the entry for that name on The Plant List website.
