colour from yellowish to pink. The edges of the petals show a few glands and are 

 tufted ciliate. 



A considerable number of forms of this variety are known in cultivation in 

 which slight differences occur in the length and shape of the petals, ^sculus Lyoni 

 and ^sculus Whitleyi are apparently sub-varieties of this hybrid. The forms with 

 red flowers are often known in gardens as Pavia rubra, a name which belongs 

 properly to ^sculus Pavia. 



Distribution 



This tree occurs in alluvial soil of river valleys and on moist mountain slopes, 

 from Pennsylvania southward to Georgia and N. Alabama ; and westward to 

 S. Iowa, Indian Territory, and W. Texas. Sargent says that when at its best on 

 the slopes of the Tennessee and Carolina mountains, it sends up a straight shaft 

 sometimes free of branches for 60 to 70 feet, and reaches a total height of 90 feet.

Cultivation 



According to Loudon this species was introduced into England in 1764, but 

 though more common in cultivation than any ^sculus except A. Hippocastanum, 

 and apparently not particular about soil, it does not attain any great size. It is 

 perfectly hardy at Colesborne, and ripens fruit in most years, from which I have 

 raised seedlings, which, however, do not grow so fast or well as those of the 

 common horse-chestnut. A seedling raised from a tree at Tort worth in 1905 

 was 6 inches high in the first year, and some raised from seed which I gathered 

 in the Arnold arboretum, which germinated earlier, were much injured by the frost 

 of May 21-22. 



At Syon there are two trees, probably of a great age, both grafted on the 

 common horse-chestnut. One is 65 feet high by 4 feet 4 inches in girth ; the other 

 is 56 feet high by 6 feet 4 inches in girth, with a bole of 7 feet, dividing into three 

 stems, which form a wide-spreading crown. A tree at Belton Park, Lincolnshire, 

 was, in 1904, 50 feet high by 3 feet 4 inches in girth, with a fine straight stem, 

 drawn up in a wood. Another, crowded by other trees near the Broad Water at 

 Fairford Park, Gloucestershire, measures about 60 feet by 4 feet 5 inches. A self- 

 sown seedling was growing near it in 1903. There is also a tree, measuring about 

 50 feet by 5 feet 6 inches, at Charlton Kings, near Cheltenham.
