The flower of this magnolia is surrounded by an umbrella-like whorl of leaves. The whole tree, indeed, suggests an umbrella, so closely thatched is its dome with the glossy leaves. The twigs have a peculiar habit of striking out at right angles from an erect branch, then turning up into a position parallel with the parent branch. This feature, combined with the inevitable forking of each twig that bears a flower, gives the branches angularity and tends to destroy the symmetry of the dome.
The three recurved sepals are the distinctive feature of the flower. The whole tree is smooth, except when its young shoots unfold. The silky hairs are soon shed. Altogether, this is one of the trimmest and handsomest of our native magnolias. It attains large size in the Arnold Arboretum, proving it hardy in southern New England.
