Fraxinus 885 



in the axils of the leaf-scars. Fruit oblong ; body compressed with a longitudinal 

 furrow on each surface, and many-rayed ; wing long and obliquely truncate at the 

 apex. Buds very small, with two outer scales pinnately lobed. 



This remarkable ash was observed by Sir Joseph Hooker in South Morocco. 1 

 It also occurs in the mountainous regions of Algeria in the valleys at 4000 to 6000 

 feet altitude. In dry situations it remains a bush with very rigid and almost spiny 

 branches, and rarely flowers even when very old. On the banks of streams it grows 

 to be a small tree and produces flowers and fruit. The wood is very hard and 

 heavy, with a satin-like lustre. 



This species is rarely seen 2 except in botanical gardens, where, as at Kew, it 

 grows to be a small tree, remarkable for its diminutive foliage. It has smooth grey 

 bark. (A. H.) 



FRAXINUS XANTHOXYLOIDES 



Fraxinus xanihoxyloides, Wallich, List, 2833 ; C. B. Clarke, in Hooker, Fl. Brit. India, iii. 606 

 (1882); Brandis, Indian Trees, 444 (1906). 



This species is probably only a pubescent geographical form of Fraxinus 

 dimorpha, which it resembles exactly in habit. The young shoots are covered with 

 a minute dense pubescence. The leaflets only differ from those of F. dimorpha in 

 having a scattered pubescence all over the lower surface ; the rachis of the leaf is 

 also pubescent. 



This species occurs in Baluchistan, Afghanistan, and the north-west Himalayan 

 region, at altitudes of 3000 to 9000 feet, growing mainly in dry valleys, where it is 

 often gregarious. It is reported to attain a height of 25 feet. 



It is rare in cultivation, and forms a small tree, scarcely distinguishable in 

 appearance from F. dimorpha. (A. H.) 



FRAXINUS POTAMOPHILA 



Fraxinus potamophila, Herder, in Bull. Soc. Imp. Mosc, xli. 65 (1868); Dippel, Laubholzkunde, i. 

 98, fig. 54 (1889). 



A small tree ; branchlets glabrous. Leaflets (Plate 262, Fig. 8) small, seven 

 to nine, about i| to 3 inches long, stalked (petiolules glabrous, \ inch or more in 

 length), ovate, tapering unequally at the base, acute at the apex, coarsely serrate, the 

 serrations often ending in long points ; glabrous on both surfaces. Rachis of the 

 leaf with angled edges on its upper side, enclosing a shallow groove. Flowers

2 A tree at Coombe Wood, which had attained almost 25 feet in height, was destroyed in 1907. Mr. A. B. Jackson 

 has seen small specimens at Barron's nursery, Elvaston, where they were erroneously named E. lentiscifolia.
