From Quercus stellata this variety chiefly differs in the rounded or pointed lobes of the leaves 

 and in the often less numerous clusters of stellate hairs on the upper surface of the leaves, which 

 sometimes become glabrous or nearly glabrous above late in the season, and on the lower surface 

 are nearly glabrous, more or less densely pubescent, or often covered with long pale spreading 

 hairs in stellate clusters. Bark, winter-buds, flowers and fruit as in the species. 



A tree, sometimes from 10 to 15 metres high, with a trunk 2 metres in diameter, and stout 

 spreading branches forming a rather open round-topped head ; or sometimes shrubby.

Quercus stellata is best distinguished by the square or emarginate lobes of the leaves and by tbe numerous stellate 

 clusters of hairs which are found on their upper surface. On many forms of the variety Margaretta the lobes are 

 rounded or pointed at tbe apex, but often some of the lobes of such leaves are square at the apex, showing a close con- 

 nection between the species and the variety. On some individuals with leaves with pointed lobes the clusters of hairs 

 are abundant and persistent, on others they are much less abundant, and are sometimes persistent during the season and 

 sometimes entirely disappear before autumn, so that satisfactory characters cannot be found either in the shape of the 

 leaves or in their pubescence by which this form can be specifically distinguished. The pubescence on the lower surface 

 of the leaves varies equally in the species and in the variety, and the fruit of the variety is both sessile and pedui 

 and varies in size and shape as it does in the species. 8

 unded lobes. This is possibly a hybrid ; but the parentage is not obvious, and
