 This is the Elm of the Eastern Counties, and many examples may 

 be seen on the way to Cambridge on the Great Eastern Railway. It 

 is a large, graceful tree ; the lower branches are wide-spreading ; the 

 leaves are very unequal at the base, smooth and shining above ; and 

 the fruit is from oblong to obovate, with the seed between the centre 

 and the apical notch, the notch reaching nearly down to the seed 

 cavity. A good tree in the Cambridge Botanic Garden has been 

 authenticated by Dr. Moss. It is 58J ft. high and 49J ft. in diameter. 



43. U. nitens var. Sowerbyi Moss {Eng. Bot. 2248, ed. 3, viii. 

 t. 1286). (Fig. 12.) 



U. glabra Smith. 



This variety, established by Dr. Moss, was made known by 

 Mr. E. W. Hunnybun. It is described as a smaller tree than var. 

 Hunnybuni. The branches are shorter, and the upper ones very 

 tortuous ; the leaf-blades smaller and acute ; the fruits rather smaller, 

 obovate to elliptical. This is the tree referred to by Smith as the 

 Norfolk Elm. It is found in the hedgerows and woods of Norfolk, 

 Cambridgeshire, Huntingdonshire, and no doubt elsewhere, and is 

 often planted. 



44. U. nitens var. Hunnybuni Moss {Cambridge British Flora, 

 ii. p. 90, tab. 90, 91). 



This fine tree has been distinctively made known by Mr. E. W. 

 Hunnybun, the fine artist who is collaborating with Dr. Moss in the 

 production of the new Cambridge Flora now being published. It is 

 described by Dr. Moss as a taller and more handsome tree than the 

 variety Sowerbyi. It has longer branches, the lower spreading at 

 right angles, the upper less tortuous. The leaf-blades are longer, 

 even more asymmetrical at the base, and more acuminate. The
