NOTES ON EUCALYPTUS. 87 



flowers. Calyx-tube conoid, 5 cm. diameter, often angular, taper- 

 ing into a short pedicel. Operculum pointed and as long as the 

 calyx tube. Stamens inflected in the bud, anthers small, yellow, 

 opening in small slits near the top, filament at base, and small 

 gland at back, indubitably showing intermediate characters 

 between the anthers of E. paniculata and E. hemiphloia. 



Fruit. When immature cylindrical, with a rim round the 

 orifice; when ripe cylindrical to almost conoid, about 6 mm. in 

 diameter, hardly constricted at the orifice, rim thin, tips of valves 

 more or less sunk and rarely flush with the orifice. 



The Affinities of this species are almost intermediate 

 between E. paniculata, Sm., the Grey Ironbark, and E. 

 hemiphloia, P.v.M., the Grey Box. 



This is the first species of this genus which has been 

 named with especial reference to its hybrid character. I 

 have a large number of instances of apparently indubitable 

 hybrids, but in most cases a pictorial illustration is neces- 

 sary to make the hybridism clear, and therefore I propose 

 to describe them in my " Critical Revision " of the genus.
