Abstract

In a group of three white oaks on the grounds of the Iowa Sanitarium, one varies considerably from the others and from white oaks in general in character of leaves and fruit and in the color of the bark. The leaves are similar in shape to those of Quercus macrocorpa Michx, but are more downy beneath, resembling the leaves of Quercus bicolor, Wild, in this respect. The trunk is a little darker than the other trees otherwise it is of the white oak type. The fruits are twice or more the size of typical white oak fruits. They approach the acorns of Quercus rubra L, in size. They are more obtuse at the apex than typical white oak fruits, and their diameter relative to their length is proportionately greater. In bud and twig features the tree is typical of Quercus alba.
