Among cultivated plants the Aesculus neglecta Baenitz (Herb. Dendr. 

 without number "Breslau: Goepperthain, 1903"), not Lindley, and Hort. 

 Goettingen, A. Render, no. 1571, belong to this variety. 



It has been cultivated in the Arboretum since 1898 when a plant was 

 received from the Meehan Nursery at Germantown, Penn. (no. 8121); in 

 1900 a plant was received from the Spaeth Nursery at Berlin, Germany 

 (no. 8123); and in 1907 the seeds collected on Craggy Mountain, North 

 Carolina, by T. G. Harbison, produced a number of plants (no. 13276). 



The covering of the lower surface of the leaflets of the tree from Pike- 

 ville, Kentucky, (Horsey no. 947), is distinctly tomentose, and similar 

 tomentum occurs on several of the other specimens in this herbarium. 

 On other specimens the lower surface of the leaflets is pubescent, sometimes 

 only slightly so, showing the transition to the normal form of Aescvlua 

 octandra in which the lower surface of the leaflets is glabrous or occasionally 

 slightly pubescent early in the season with deciduous hairs except along 

 the under side of the midrib and principal veins. The amount of the pubes- 

 cence on the petioles and branchlets also varies in different individuals. 



Aesculus neglecta Lindley in Bot. Reg. xn. t. 1009 (1826).— Spach in 

 Ann. Sci. Nat. se>. 2, n. 55 (1834). 



Lindley 's description of this species was made from a tree growing in 

 the garden of the London Horticultural Society at Chiswick, which had 

 been purchased from a Monsieur Catros of Bordeaux under the name 

 Aesculus ohioensis. Spach took up Lindley 's name and spoke of the tree 

 as common in cultivation in 1834. Koehne in 1893 (Deutsche Dendr. 

 386) suggested that it was a hybrid of A. discolor and A. octandra, but the 

 margins of the petals in Lindley 's excellent plate show no trace of the 

 glands among the hairs which indicate hybrid origin in Aesculus. The 

 petals are pale yellow marked by small red blotches.
