opposite leaves; another specimen in the same herbarium from the Herb. 

 Lugd.-Biitav. and named H. Belzonii has opposite, ovate leaves and 

 nearly ripe fruits. The Japanese name Oho-Azisai given by Siebold and 

 Zuccarini merely signifies "Large Azisai" and is virtually meaningless. 



Another form is: 



Hydrangea macrophylla var. normalis f. azisai Wilson, n. comb.

This is a Japanese garden plant distinguished by its ovate to elliptic- 

 ovate leaves, and pale blue to white sterile ray-flowers on very long (2.5 

 cm.) pubescent pedicels. The vernacular name Azisai is by no means 

 restricted to this particular form and is in fact more generally applied to 

 //. serrata DC. which is common on the mountains throughout the length 

 and breadth of Japan. 



A form with white ray-flowers is: — 



Hydrangea macrophylla var. normalis f. macrosepala Wilson, n. comb.

Hydrangea hortensis var. macrosepala Rehder in Bailey, Cycl. Am. Hort. II. 



785 (1900). 

 This garden form is characterized by its white, toothed, sterile ray- 

 flowers. 



A form with pink ray-flowers is: — 



Hydrangea macrophylla var. normalis f. rosea Wilson, n. comb.
