AFFINITIES. 



1. With E. longieomis F.v.M. (Red Morrel). 



The fact that Western Australians call two trees by the same name of Morrel 

 shows that there must be important points of similarity between them. Speaking of 

 the two trees as they grow in the Kalgoorlie district, Mr. Forester J. M. Cusack 

 compares them as follows : — 



" Red Morrel. — This tree grows to a height of 60 feet and is 3 feet in diameter at 4 ft. 3 in. from 

 the ground. It has a rough bark for 10-15 feet up the bole. The limbs are clean, or l gum bark,' which 

 is a reddish tint. The limbs form an open or spreading top, and the leaves hang down. The bark when 

 cut with an axe is red between the rough and the inner bark. The wood is of a reddish colour to the 

 heart. 



"Black Morrel. — The same particulars apply as -to Red Morrel. except that the bark is coarser 

 at the butt, and the limbs are whiter in the bark than the Red Morrel. When the bark is cut with an 

 axe, it is more gummy and the inner bark is of a light yellow colour. The wood is very dark to the 

 heart, and in some cases jet black." 



I have two (only two) specimens of bark, but they are excellent; that of 

 E. longieomis has flatter flakes or ridges, while that of E. melanoxylon is ribbed like an 

 Ironbark. The new species is allied in the general appearance of the tree, including 

 the mature foliage, and also in the glaucous suckers, but the anthers place it in a 

 different section. The operculum of E. longieomis is longer, and the fruit more pear- 

 shaped, with the tips of the valves more awl-like, but as I hope to figure some additional 

 material of this species, which has lately come into my possession, in an early Part, it 

 will be convenient to resume the comparison then. 



2. With E. salubris F.v.M. 



For the " Gimlet," see Part XXXVI, p. 156, with Plate 150. E. salubris is a 

 Gum, with a twisted trunk which differentiates it from all other Eucalypts ; the timber 

 is pale brown, while the foliage is rich in oil. The two species, however, come very 

 close to each other because of the similarity of their anthers. 



It also differs in the slightly longer calyx, which does not show the demarcation 

 of the calyx with the operculum as distinctly as E. salubris does. The common peduncle 

 is also more slender, and so are the pedicels. The style of E. melanoxylon is broad and 

 distinctly triangular at the base, and gradually diminishing upwards, while the stigma 

 is obliquely elongated, which appears to be unique, as it does not appear to have been 

 noticed in any other species. The fruits are about the same size as those of E. salubris, 

 but they are more turbinate with or without a small band at the top, truncate 

 throughout, with more or less exsert, spreading valves.
