C. S. Sargent 



Aesculus glabra var. monticola, n. var. 



Differing from the type in its dwarf habit, small fruit and often 7 leaflets. 



Leaves 5-7, usually 5-foliate, their petioles glabrous, 7-15 cm. in length; 

 leaflets oblong-obovate to elliptic, abruptly or gradually narrowed and 

 long-pointed at apex, cuneate at base, coarsely often doubly serrate with 

 acuminate teeth, glabrous with the exception of a few short hairs early 

 in the season on the upper side of the midrib and principal veins, 10-12 

 cm. long and 4.5-5 cm. wide, their petiolules glabrous or sparingly pilose, 

 1-10 mm. in length. Flowers rather smaller but otherwise as in the type. 

 Fruit subglobose, 1.5-2 cm. in diameter, usually 1-seeded; seeds subglobose 

 or depressed and often nearly twice as broad as high, dark chestnut brown 

 and marked by an oval or nearly circular hilum 6-7 mm. long. 



A shrub 1-2 m. tall.
