scribed it but villose. He failed, however, to notice the glands scattered 

 among the hairs on the margin of the petals which indicate that it is a 

 hybrid between a species of the Eupaviae and one of the Octandrae. 



X Aesculus mutabilis var. penduliflora (A. discolor mollis X neglecta), 

 n. hyb. 



Leaves 5-foliolate, their petioles glabrous, 10-16 cm. long; leaflets 

 oblong-lanceolate, acuminate and long-pointed at apex, gradually narrowed 

 and cuneate at base, finely serrate with gland-tipped teeth, dark green and 

 glabrous except on the midrib and veins above, pale and soft pubescent 

 below, 12-16 cm. long, 4-5 cm. wide, with 22 or 24 pairs of primary veins; 

 petiolules pubescent, 7-10 mm. in length. Flowers opening early in June, 

 on slender glandular pedicels 5-10 mm. long, in narrow slightly pendent 

 sparsely flowered densely pubescent clusters 14-16 cm. in length; calyx 

 tubular, reddish covered with red glands, 5-6 mm. in diameter; corolla 

 yellow, glandular, the margin of the petals covered with liairs mixed with 

 glands. Fruit nearly globose, smooth with a thin pericarp; seed sub- 

 globose, dark chestnut brown and lustrous, 2-2.5 cm. in diameter, the 

 hilum oblong or oval, 8-10 mm. in length. 



As it grows in this Arboretum this is a narrow slender tree now about 

 8 metres in height, with a trunk 25 cm. in diameter covered with thin dark 

 brown scaly bark; it was presented to the Arboretum in 190-2 by the Spaeth 

 Nursery near Berlin, Germany, under the name of Aesculus hum Ms X lutca. 



The shape of the leaflets and the elongated flower clusters point to the 

 typical form of A. neglecta, while the pubescence on the lower surface of the 

 leaflets and the color of the flowers suggest that A. discolor mollis may 

 have been the other parent. The long narrow leaflets and the elongated 

 and pendent clusters of brilliant flowers make this one of the most distinct 

 and beautiful of the hybrid Buckeyes. 



X Aesculus mutabilis var. induta (A. discolor mollis X neglecta), n. 

 hyb. 



Differing from the type in the pale tomentum covering through the 

 season the lower surface of the leaflets. 



This variety is based on two of the three plants presented in 1909 to the 

 Arboretum by the Hesse Nursery in Weener, Germany, as Aesculus (Paria) 

 rosea nana "de semis." It is probably the Aesculus neglecta Baenitz 

 (Herb. Dendr. without number "Breslau: Sudpark, 1905"), not Lindley. 

 It was cultivated in 1904 in this Arboretum under the name of A. octandra 

 hybrida (No. 1636-2) now dead. 



CORRECTION 



In the second edition of the Manual of the Trees of North America, 

 806 (December 1921), the Marlberry, a small tree of extreme southern 

 Florida, was transferred from the genus Icacorea to Ardisia and called 

 A . paniculata Nuttall. Nuttall, however, never made such a combination,
