AFFINITIES. 



1. With E. micrantha DC. 



Speaking generally, E. hcemastoma grows on sour, rocky land, while E. micrantha 

 grows on better drained, sandy soil. E. hcemastoma differs from E. micrantha in the 

 following characters : It is a smaller tree, with broad, glossy, green leaves, larger buds 

 and fruits, and also has thicker peduncles and pedicels. The suckers, which are 

 broad, are also a useful character to separate it from E. micrantha. . 



2. With E. Sieberiana F.v.M. 



These species are allied in the broad, lanceolate, juvenile leaves, and in the heavy 

 adult foliage; also in the large buds and large pear-shaped fruits. Some of the fruits 

 when detached are difficult to separate from those of E. Sieberiana and also from 

 E. Consideniana ; but the two species, except as depauperate growths, are very 

 different, E. hcemastoma being a somewhat scrambling White Gum, and E. Sieberiana 

 a tall, erect tree, with bark often resembling that of an Ironbark.
