away to the eastward." Then we have " The precise geographic limit of this 

 Eucalypt remains as yet unknown ; it belongs probably to the tertiary limestone 

 formation, and may thus have a very extensive range " (Mueller, Forest Besources 

 of Western Australia). 



I have seen the following specimens : — 



(1) " Point Malcolm " (Maxwell). In immature bud. Evidently the type. 



(2) "West Australia" (T. Drummond). The bud scarcely formed, and 

 assumed to be E. angustissima because of its narrow leaves. 



(3) " Israelite Bay " (no collector). In fruit only. 



(4) " Towards the Tone River " (Th. Muir, 1880). This has immature buds, 

 very much like that of the type, but with much broader leaves. The fruits are 

 conoid, different to those of the Israelite Bay specimen. 



AFFINITIES. 



I remind my readers that E. angustissioia, F.v.M. is still too imperfectly 

 known to render dogmatic statements as to its affinities possible. 



1. With E. salubris, E.v.M. 



" It is allied in many respects to E. salubris, but the flower-stalks are not 

 dilated, while the leaves are narrower than in any other Eucalypt." (Mueller, 

 Forest Resources of Western Australia.) 



AVe, of course, know but little about E. angustissima in the bush, but the 

 two species can hardly be confused from herbarium specimens. Both E. salubris 

 and E. angustissima have what I have termed " egg-in-egg-cup " buds, but I do not 

 know the similarity "in many respects." The leaves and fruits sharply divide them. 



2. With E. oleosa, F.v.M. 



The affinity is suggested by Mueller. Attention is invited to Plates 65 and 

 66, Part XV of the present work. The only resemblance seems to lie in the buds, 

 which, although as a rule are very different to those of E. oleosa, occasionally 

 present some resemblance (e.g., Plate 65, fig. 6a). E. oleosa is exceptionally very 

 narrow leaved (e.g., Plate 66, fig. 2a). 



3. With E. calycogona, Turcz., var. gracilis iE. gracilis, E.v.M.). 



This affinity is suggested by Mueller. The variety gracilis is figured at 

 Plate 12, Part III of the present work, but the resemblance is not close, even if 

 allowance is made for the fact that in exceptional shrubs the leaves of var. gracilis 

 are even narrower than depicted. The buds of the latter are sub-angular and the 

 fruits quite different.
