586 ON EUCALYPTUS GUN Nil, HOOK. F., 



They give some idea of the difficulty of dealing with these 

 aberrant forms. 



Ben Lomond, i^ew England (J.H.M.). In 3's. A coarse form 

 common enough in New England, on the Monaro {e.g., Nimity- 

 belle) and elsewhere ; comes nearest to var. ruhida. 



The following forms I at present place between var. acervula 

 and var. ruhida : — 



" Flooded Gum," Glen Innes (H. Deane) ; " White Gum," 

 multiflowered. Glen Innes (H. Deane). 



Near Bolivia (not far south of Tenterfield) and just west of 

 Dividing Range; also " White Gum" of Cottesbrooke (J.H.M.). 

 Broad suckers, yet a typical Manna Gum; multiflowered. This 

 form occurs at Tenterfield and New England generally. A 

 scrambling tree found on flats. 



" White Gum," Gwydir (Leichhardt). In leaf only. 



Richmond River, Mrs. Hodgkinson; multiflowered (Herb. 

 Melb.). 



The following I place between vars. acervula and 7naculosa : — 



Trees with perfectly smooth trunk; plum-coloured patches; in 

 a low-lying situation 17 miles east of Walcha (J.H.M.). 



" Blue Gum," head waters of the Clarence (F. R. Mecham). 



Following are some notes on E. Gut^nii in South Australia : — 



I give some separate notes at this place, as the occurrence of 

 the species in that State requires further investigation. 



There is a good figure of a form of the species in Brown's 

 " Forest Flora of South Australia" under the name of "White 

 Swamp Gum." This is multiflowered (up to 6 as shown in the 

 plate), and the fruits are conoid-hemispherical. This form is 

 perhaps nearest to var. acervula. It is very common in Mt. 

 Gambler low-lying swamp country (W. Gill). 



It is identical with a specimen from Argyle Station, Mt. Gam- 

 bier, collected by Mueller about 1847, and labelled ''E. viminalis. 

 Bark thick-scaly (schrundig) at butt." This is the kind of bark 

 shown in Brown's plate; it is not rare in the species, and it is 

 doubtless the "Cortex rimosus nigricanti-cinereus" of Euc. falci-
