sparsely hairy (described as glabrous by Scheele), with hairy midribs. The 
fruits are also different. It seems nearest related to F. holotricha, Koehne, 
especially in the sparsely pubescent fruit (though the fruit of the latter is 
unknown, the carpel is pubescent). But it does not agree with the specimens 
(from Spath’s nursery !) growing in the Kew arboretum. The pubescence 
of these trees is not exactly the same, and the leaflets, correctly described as 
9-13 to each leaf, are not of the same shape. It is not possible to give these 
wild specimens the same name as garden specimens of unknown origin 
which have never fruited, unless the agreement is absolute, although 
F. holotricha may be a garden hybrid of F. Pallise with some other species, 
which might explain its absence of fruit. It must be agreed that F. holotricha 
is nearer to F. Pallise than to any other described species of Fraxinus, 
but there the matter must be left until it is more completely known. Its 
pubescence distinguishes F. Pallise from any other Old World ash.
