15. Fraxinus texensis, Sargent. Texas. See p. 907. 



Leaflets five to nine, i\ to 3^ inches long, shortly acuminate, shining

17. Fraxinus rhynchophylla, Hance. N. China, Manchuria. See p. 892. 



Leaflets five to seven, 3 to 4 inches long, coriaceous, terminating in an obtuse-

18. Fraxinus chinensis, Roxburgh. Central and Southern China. See p. 895. 



Leaflets seven to nine, 3 to 4 inches long, coriaceous, shortly cuspidate at the 

 apex, crenately serrate. 



19. Fraxinus obovata, Blume. Japan. See p. 895. 



Leaflets five to seven, 2 to 3 inches long, membranous, variable in shape, 

 irregularly serrate, with minute curved bristles on the lower surface and petiolules, 

 which are also present on the rachis of the leaf. 



20. Fraxinus longicuspis, Blume. Japan. See p. 897. 



Leaflets five, 3 to 4 inches long, membranous, very pale beneath, abruptly 

 contracted into a long cuspidate apex, crenately serrate. 



21. Fraxinus Ornus, Linnaeus. S. Europe, Asia Minor. See p. 887. 



Leaflets five to nine, 2 to 3 inches long, membranous, shortly acuminate, 

 serrate. 



22. Fraxinus floribunda, Wallich. Himalayas, Upper Burma. See p. 890. 



Leaflets seven to nine, 4 to 6 inches long, membranous, apex long-acuminate, 

 serrate ; lateral nerves prominent and numerous. 



23. Fraxinus quadrangulata, Michaux. N. America. See p. 900. 



Branchlets quadrangular and four-winged. Leaflets seven to nine, 3 to 5 inches 



long. 



f f Leaflets sessile or sub-sessile.* 



24. Fraxinus Spaethiana, Lingelsheim. Japan. See p. 897. 



Leaflets seven to nine, 4 to 6 inches long, coriaceous, lanceolate, long- 

 acuminate, irregularly and often crenately serrate. Distinguished from all 

 other species in cultivation by the dilated swollen base of the leaf-stalk. 



25. Fraxinus lanceolata, Borkhausen. N. America. See p. 906. 



Leaflets seven to nine, 3 to 6 inches long, lanceolate, long-acuminate. Rachis 

 grooved. 



26. Fraxinus Berlandieriana, De Candolle. Texas, Mexico. See p. 907, note 1. 



Leaflets, five to seven, 2 to 3 inches long, oval or obovate. Rachis grooved. 



1 Fraxinus lanceolata (cf. No. 21), has occasionally the leaflets distinctly stalked, and might on that account be sought 

 for here. 



2 Cf. No. 3 1 A. Two forms of this species occur in cultivation, differing in the absence or presence of pubescence on the 

 branchlets and leaf-rachis. 



3 Fraxinus Elonia (cf. No. n), sometimes having an open continuous groove on the rachis, might be sought for here.
