This Wistaria is endemic in Japan, and it is common on the margins of woods, 

 in thickets and by the sides of streams and lakes from northern Hondo southward. 

 It is much cultivated in temple grounds, parks, and gardens where several distinct 

 forms have originated. The young leaves are densely clothed with straight ap- 

 pressed hairs which soon disappear, and the adult leaves are quite glabrous. This 

 species is closely related to W. sinensis Sweet, which has much larger flowers and 

 fewer (5 to 7) pairs of leaflets and which blossoms fully two weeks earlier and is not 

 so hardy a plant. 



Willdenow's name is founded on Thunberg's plant, and there is no valid reason 

 why it should not be accepted for the wild Wistaria of Japan. Thunberg says " ra- 

 cemis longissimis," but it must be remembered that he was contrasting it with 

 species of the genus Dolichos, and further on in the description he says the racemes 

 are often a foot long. As a matter of fact, on wild specimens before us the racemes 

 vary in length from 10 to 35 cm. Houttuyn's figure, which is probably based on 

 a specimen of Thunberg's, is very good. Siebold & Zuccarini's W. brachybotrys 

 has been a source of difficulty to botanists and horticulturists alike, but the plant 

 so named is certainly merely a state of the wild Japanese Wistaria. Such short 

 racemes occur occasionally in tho'Spring, but are much more common in late summer, 

 when some plants often hear a sparse second crop of flowers. 



The vernacular name given by Siebold & Zuccarini means Mountain or Wild 

 Wistaria and is still in common use in Japan. 



According to Spae this Wistaria was introduced from Japan to the Botanic 

 Gardens at Ghent by Siebold in 1830. It and its variety macrobotrys were intro-
