The figure represents one of the seedlings from Terling Place, 

 drawn to the natural size, together with an enlarged view of the 

 base of a cotyledon seen from behind. The stem, cotyledons and 

 leaves are hairy, the upper surfaces of the leaves being more hairy 

 than the lower. The cotyledons are about § to T V of an inch long

pronounced auricles at the base. 



foliag 



seedling are arranged in pairs, and it appears to be some time 

 before the characteristic alternate arrangement of the adult tree is 

 assumed. The dentation of the leaves is also of a simple type. 

 A comparison of these seedlings with those figured by Hempel 

 and Wilhelm* shows that the auricles of the cotyledons are 

 typical of the seedlings of the genus Ulmus. 



From their figures of the seedlings otll. campestris, U. Montana 

 and U. effusa, it appears that the cotyledons are similar in all 

 cases, but the first foliage leaves are somewhat different in the 

 three species, those of U. montana being larger and more definitely 

 pointed at base and apex than those of U. campestris, whilst those 

 of ILeffusa are more decidedly ovate m outline and have more 

 pronounced teeth. In all cases the first foliage leaves show a 

 decussate arrangement. 



The first layer of cork is beginning to be shed from the 

 hypocotyl of the seedling figured on the opposite page.
