clouds of bloom in June and Cornelian cherry with 

 its pretty clusters of dull yellow flowers which are 

 almost the first to break out in early spring, before its 

 leaves are out. Over on the border of the Drive, a 

 little northwest of the sweet gums and buttonwoods 

 you will find the River or Red Birch with gray-brown 

 bark touched with cinnamon and rhombic-ovate leaves.

 bright scarlet fruit, large, for hawthorns (about half
