11. lanceolata, Borkh. (F . viridis, Michx., in part. 

 F. pennsylvdnica var. lanceolata, Sarg.). GREEN ASH. 

 Tree, to 60 ft: branchlets and petioles glabrous: Ifts. 

 5-9, stalked, ovate to oblong-lanceolate, irregularly 

 serrate, green on both sides, almost glabrous, 2-5 in. 

 long: fr. oblanceolate, with decurrent wing, hence 

 body margined, about \Yi in. long. Canada to Fla.,

12. pennsylvanica, Marsh. (F. pubescens, Lam.). 

 RED ASH. Tree, to 60 ft.: branchlets and petioles

 beneath, 3-6 in. long: fr. linear-spatulate, about 2 in. 

 long, with somewhat decurrent wing. Canada to Fla., 

 west to Dakota and Mo. S.S. 6:271. This species 

 varies considerably in the amount of pubescence and 

 the shape of the Ifts., and many forms under different 

 names are grown in European nurseries and gardens. 

 Var. aucubaefolia, Hort., is a form with less pubescent 

 Ivs., blotched yellow. There are also variegated forms 

 with the Ivs. blotched white or edged white.
