Zelkova 915 



Japan, and Z. crenata, Spach, inhabiting the Caucasus and North Persia. The third 

 species, Z. cretica, Spach, is a shrub growing in Crete and Cyprus, which has not yet 

 been introduced, and does not come within the scope of our work. The following 

 species, also a shrub, is only known in cultivation : 



Zelkova Verschaffeltii, Nicholson, Kew Handlist of Trees, 145 (1896). 

 Zelkova japonica, Dippel, var. Verschaffeltii, Dippel, Laubhohkunde, ii. 39, fig. 14 (1892). 



A shrub or small tree. Branchlets slender, pubescent, with white hairs. 

 Leaves (Plate 267, Fig. 8), coriaceous, variable in size, from \\ inch long by 

 f inch wide to 2^ inches long by \\ inch wide, oval, acuminate at the apex, 

 cuneate and unequal at the base, divided by the midrib into unequal halves, 

 the larger half with six to eight nerves, the smaller half with four to seven 

 nerves, each nerve ending in a long triangular tooth, tipped with a short 

 cartilaginous point ; margin ciliate ; upper surface dark green, with scattered white 

 pubescence ; lower surface light green, with downy white pubescence, densest on the 

 midrib and nerves ; petiole, \ inch to \ inch, pubescent. Buds, often two together 

 in an axil, small, globose, pubescent. Fruit similar to that of Z. crenata, but 

 slightly smaller in size. 



This species, which resembles an elm in having asymmetrical oblique leaves, was 

 considered by Schneider ' to be a peculiar variety of Ulmus glabra, and is occasion- 

 ally met with in cultivation, as Ulmus Verschaffeltii, and Ulmus pendula laciniata 

 Pittcursii. 



A tree, 15 feet high, in the nursery of the Paris Municipality, specimens of which 

 have been sent us by M. Vacherot, produced flowers and fruit this year ; and the 

 fruit, hitherto unknown, proves to be that of a Zelkova. Z. Verschaffeltii is not 

 known in the wild state, though Koehne 2 states that O. Kuntze collected specimens 

 of Z. crenata in the Caucasus, which strongly resembled it. It is possibly a hybrid 

 between Z. crenata and Z. cretica, and was first noticed by Dippel in 1892.
