1 Fraxinus lanceolata (cf. No. 21), has occasionally the leaflets distinctly stalked, and might on that account be sought for here.
2 Cf. No. 31a. Two forms of this Species occur in cultivation, differing in the absence or presence of pubescence on the branchlets and leaf-rachis.
3 Fraxinus Elonsa (cf. No. 11), sometimes having an open continuous groove on the rachis, might be sought for here.
