884 The Trees of Great Britain and Ireland 



Koehne suggests. It occurs in England in cultivation under the erroneous name of 

 F. chinensis, 1 the plants at Kew having been obtained from Sir C. W. Strickland, 

 who tells us that it was sent out by the Royal Horticultural Society some years ago. 

 Plants cultivated as F. Elonza are usually F. oxycarpa. (A. H.) 



FRAXINUS WILLDENOWIANA 



Fraxinus Willdenowiana, Koehne, Deutsche Dendrologie, 515 (1893). 



Fraxinus parvifolia, Willdenow, Berlinische Baumzucht, 124, t. 6, f. 2 (1796) (non Lamarck); and 

 Sp. PI. iv. 1101 (1805). 



A small tree. Shoots glabrous, lenticels white. Leaflets (Plate 265, Fig. 24), 

 seven to eleven, 2 to 3J . inches long, subsessile (except the terminal one, which is 

 much the largest and stalked), ovate, base broad and unequally cuneate, apex 

 acuminate; serrations coarse and sharp with minute incurved points; both surfaces 

 glabrous. The leaflets increase in size from the base to the apex of the leaf, the 

 rachis of which is winged, the wings usually not meeting on the upper side, but 

 forming an open groove. Fruit unknown. 



This species was considered by Willdenow to be different from F. parvifolia, with 

 which he had first identified it, yet he left it with this name. Koehne has accordingly 

 given it a new name. It is sometimes met with in cultivation under the name of 

 F. rotundifolia. It is readily distinguished by the large terminal leaflet and the 

 open-grooved rachis from the other glabrous species. Its native home is uncertain. 

 It is perfectly hardy at Kew and has very distinct foliage. (A. H.) 



FRAXINUS DIMORPHA 



Fraxinus dimorpha, Cosson et Durieu, Bull. Soc. Bot. France, ii. 367 (1855); Mathieu, Flore 



Fores Here, 245 (1897). 

 Fraxinus xanthoxyloides, Wallich, var. dimorpha, Wenzig, in Engler, Bot. Jahrb. iv. 188 (1883). 



A small tree attaining 40 feet in height. Young shoots purple, slender, glabrous, 

 obscurely quadrangular. Leaves (Plate 262, Fig. 1) on barren branchlets with 

 seven to nine small leaflets, which are \ to f inch long, sessile or subsessile, ovate or 

 oval, crenulate-serrate, and glabrous except for pubescence on the midrib towards 

 the base on the under surface ; leaf-rachis usually glabrous, strongly winged, the 

 wings spreading and forming a very open channel. The leaves on flowering shoots 

 are larger, with seven to eleven leaflets, oblong-lanceolate, acute and serrate. 

 Flowers (section Sciadanthus) perfect, without a corolla, but with a calyx which 

 persists under the fruit, grouped in fascicled cymes on the previous year's shoot 



1 F. chinensis, Roxburgh, a native of China, is entirely distinct from F. Elonza, which is closely allied to F. oxycarpa, a 

 Mediterranean species. Koch, in Dendrologie, ii. pt. I, 247 (1872), mentions F. Elonza as having been in cultivation some 

 years, and considered it to be probably a variety of F. angnstifolia.
