Operculum. — Double operculum or lavge calyptra-like bracts enveloping the whole head of 

 flower-buds, and only thrown off when the individual flower-buds are nearly ready to throw off their own 

 opercula. 



Fruit. — Often pale brownish and glossy, subcylindrical, 5-celled, corrugated, partly due to drying 

 (but also corrugated in a green state) ; the rim slightly projecting. 



The history of the present species affords an excellent instance of the advantage 

 of publishing figures and all available data in regard to a doubtful species. It has set 

 my friends and myself to work, and the result is summarised in the present Part. 



RANGE. 



The species is restricted, so far as is known at present, to New South Wales, in 

 the neighbourhood of the Hawkesbury River, Poit Jackson, and the National Park 

 (a few miles to the south). The most northerly locality known to me is the Penang 

 Range, near Woy Woy, Gosford district. 



South of Port Jackson. — Following are specimens seen by Mueller. 



Bulli (W. Kirton). Two specimens labelled by Mueller (a) " E. virgata Sieber. 

 Identical with an original specimen of Sieber's in Bonder's herbarium (in bud only)."' 

 (b) " E. virgata var. Luehnmnniana." 



There is a third specimen in the Melbourne Herbarium from Illawarra, labelled 

 " Eucalyptus Luehmanniana F.v.M. (E. stricta var. (?) ); E. virgata Sieber.)" 



Specimen (a) could not have been obtained from the township of Bulli, but 

 probably a little to the north, on the high land in the direction of what was afterwards 

 known as the National Park. Mr. Kirton lived at Bulli. 



National Park (many collectors). 



North of Port Jackson. — "From the north side of The Spit, about 200 yards 

 from the ferry, on the right-hand side of the zig-zag road. About 15 feet high, slender, 

 and with a smooth bark. Only three or four trees in the clump." (J. H. Camfield.) 



" Mallee-like shrubs or sometimes reduced to two stems, 10-20 feet high. Timber 

 very hard. Branches almost slate blue in colour. Young tips conspicuously bright 

 yellow, contrasting with the glaucous green of the adult foliage." The Spit (W. F.. 

 Blakely and J. L. Boorman). 



Then it has been sent to me from Spit-road, Manly (J. L. Boorman, 7106). The 

 Spit (Dr. J. B. Cleland). Manly (Rev. J. W. Dwyer, No. 367). Spit-Manly road (C. 

 Lindgren, No. 4). But all four specimens were obtained from precisely the same limited 

 locality as visited by Messrs. Camfield, Boorman, Blakely, and myself. 



We now ascend Middle Harbour.
