206 JOURNAL OF THE ARNOLD ARBORETUM [vol. vi 



This remarkable Willow forms a dense head subglobose in young trees, 

 semiglobose and broader than high in older trees, and looks as if it had 

 been pruned, as the twigs at the end of the more or less upright branches 

 are of nearly the same length and no leading shoots are produced. This 

 Willow is much planted in the neighborhood of Peking and is called by the 

 Chinese "man-t'ow-liu" (bread willow) in reference to its shape which in 

 older trees resembles a round loaf of bread. It was introduced by F. N. 

 Meyer to America in 1906; plants at Chico, California, have grown rapidly, 

 attaining in 6 years 20 feet in height and 30 feet in spread and have retained 

 their peculiar habit as the photograph reproduced in the Bulletin of foreign 

 plant introductions cited above shows. The only figure showing the habit 

 of typical S. Matsudana known to me is one published by Hers (in Bull. 

 Soc. Dendr. France, 1923, t. 14).

A typo recedit ramis ramulisque tortuosis. 



This peculiar form with tortuous and twisted branches is cultivated by 

 the Chinese under the name "lung chao liu" (dragon's claw willow). Ac- 

 cording to Hers it is short-lived, because susceptible to attacks by insects 

 which find shelter between the twisted branches. Apparently now in 

 cultivation in Vilmorin's Nursery at Verrieres near Paris.

As Wenderoth's name, applying apparently to the same form as Seringe's 

 S. depressa nitida which I take to be the oldest varietal name of that vari- 

 ety or group of forms called by many authors S. repens var. arenaria, has 

 been overlooked or passed over by most authors, I have given an enumer- 

 ation of the synonyms of this variety. Toepffer in his Salices Bavariae,
