4. With E. uneinata, Turcz. 



This species is only brought under review because it sometimes bears very 

 narrow leaves, and because Mueller suggested the comparison. Individual shrubs 

 with very narrow leaves are more common than would be surmised from casual 

 perusal of Plate 62, Part XIV of this work, which- simply enumerates the various 

 forms without reference to the relative frequency of individuals. On the evidence 

 of buds, anthers, filaments and fruits the affinities of the two species are not close, 

 but we must ever bear in mind the paucity of material of E. angustissima. 



5. With E. leptopoda, Benth. 



Bentham places E. angustissima next to E. leptopoda, Benth., which, how- 

 ever, includes E. sal mono phloia, P.v.M., a species carved out of it later. (See Part 

 XVII, p. 217). 



There is certainly some resemblance in the fruits of E. angustissima and 

 E. leptopoda (compare, e.g., fig. 6b, Plate 73, Part XVil of this work), but the fruits 

 of E. angustissima are nearly sessile, while the leaves of E. leptopoda, though narrow, 

 are by no means as narrow as those of E. angustissima. 



6 and 7. With E. linearis, Dehnh., and E. amygdalina, Labill. 



The typical forms of both species have linear leaves, and hence remind one of 

 E. angustissima. For E. linearis, see fig. 5, Plate 30, Part VI of this work, and for 

 E. amygdalina see fig. 1, Plate 29. But the leaves of both species are usually 

 thinner and more aromatic, while the buds, anthers and fruits are different. 

 E. linearis is a smooth-barked tree ; the bark of E. amygdalina is more or less 

 fibrous ; both are much larger species than E. angustissima. At the same time we 

 must bear in mind that we are ignorant of the size to which E. angustissima may 

 attain. 



8. With E. apieulata, Baker and Smith. 



This is another narrow-leaved species. It is figured at 3, Plate 44, Part IX 

 of the present work. It differs in all essential characters from E. angustissima. 



9. With E. eneorifolia, DC. 



On the label of a specimen " Towards the Tone River, Th. Muir," Mueller 

 has the note " Xear E. eneorifolia of Kangaroo Island." 



This suggested resemblance or affinity occurred to me independently, but 

 cannot be fully discussed until we know more about E. angustissima. 



E. eneorifolia is figured on Plate 60, Part XIII of the present work, and some- 

 times has leaves nearly as narrow as those of E. angustissima, while the ventral 

 seaming of the leaf is common to both species. The fruits of the two species are 

 dissimilar, and the buds appear to be permanently different. 



Mueller suggests E. angustissima as an oil-yielding species ; E. eneorifolia 

 is one of proved value in this respect.
