upon, in close crowded clusters, sessile umbels, near the 

 ends of last season's shoots, before the leaves appear. 

 They are very plum-like, five-petaled, and white. The 

 fruit follows in late summer, still green in August, 

 nearly round, or rather roundish egg-shape, a little 

 flattened. When ripe it becomes a reddish-orange color. 

 The stone is very much flattened, and has an almost 

 razor-like border. The leaves of the tree are pubes- 

 cent when young, but finally become smooth. They are 

 quite long-pointed and have rounded bases. In general 

 form they are ovate. Their margins are doubly and 

 coarsely serrate. 



Salix alba. (White Willow. No. 70.) Take the 

 right-hand Walk at the Gate, One Hundred and Tenth 

 Street and Central Park West, and go down the series 

 of steps there ; bend to your left, toward the Arch that 

 runs under the Drive. In between the steps and the 

 wall that carries the Arch and the Drive, you will see 

 two willow trees. These are pretty fair examples of the 

 white willow. They have lanceolate leaves, narrow and 

 pointed, finely serrate and are covered with white, silky 

 hairs. These hairs are very dense on the undersides 

 of the leaves and give them the white appearance that 

 has given the tree its name white (alba) willow. In 

 other parts of the Park you have met the golden willow. 

 It is almost the same as the white willow, except that its 

 branches and end shoots turn in winter to a beautiful 

 brassy yellow. This is the variety vitellina, of the white 

 willow. Opposite the white willows here, on the right 

 of the Walk, almost directly opposite the last pair of 

 steps, are two hop-hornbeams, with shaggy bark.
