Of the fourteen, three of the Chinese (>S^. cuscutaeformis, 

 Lodd., S. rufescens, Balf. fil., and S. Veitchiana, Balf. fil.), 

 and four of the Japanese (S. cortusaefolia, Sieb. et Zucc, 

 *S^. Fortunei, Hook., S. madida, Makino, S. sarmentosa, 

 Linn, fil.) are in cultivation. 



The longest and perhaps the best known species is 

 *S^. sarmentosa, Linn. fil. — the so-called Strawberry Saxi- 

 frage, and bearing also several other names : Wandering 

 Jew, Aaron's Beard, Old Man's Beard, Mother of Thousands, 

 Sailor Plant, — familiar to everyone in its white-veined 

 hairy leaves and long runners — the flower with a large 

 yellow one-sided tubercled disk. Cultivated in the East as 

 in the West, it has probably spread from Japan to China 

 where it is found in isolated areas always apparently about 

 large cities. Its variety tricolor is a striking well-known 

 greenhouse plant. 



S, cuscutaeformis, Lodd., is another plant of cultivation. 

 Its wild habitat is unknown. There is no record of it in 

 the careful account of their Flora by Japanese botanists 

 and it is assumed to be a Chinese plant. It may be 

 regarded as a minute S. sarmentosa, Linn, fil., the leaves
