Roe's River runs into York Sound, and must not be "confused with a river of 

 similar name in the Northern Territory. 



Bentham also records it from Surgeon Bynoe (Captain J. Lort Stokes' 

 Expedition, 1838). 



Western Australia. 

 I have seen the following north-west specimens :— 

 Leaves only (Harry Stockdale). 



King's Sound, fruits and a leaf (W. W. Froggatt, seen by Mueller). 

 Leaves, buds, and fruits. Lennard River (W. V. Fitzgerald, No. 333). 



Native Well, 9 miles from Goody Goody, near Derby. (W. V. Fitzgerald, 

 No. 333 bis.) 



Six miles north-east of Mt. Eliza. (W. V. Fitzgerald, No. 707). 



Mt. Anderson and Grant Range. (W. V. Fitzgerald). 



Balmarringarra, not far from coast; Exmouth to King's Sound. (Dr. H. 

 Basedow. ) 



AFFINITIES. 



E. perfoliata, as a member of the Corynibosae, stands in a class by itself, because 

 of its connate leaves and small anthers. 



If fruits alone are available for comparison, they may be compared with those 

 of E. terminalis (Plate 164, Part XL) ; E. pyrophora (Plate 166, Part XL) ; E. Foelscheana 

 (Plate 169, Part XLl); E. Abergiana (Plate 170, Part XLI). If buds are alone 

 available, they are most likely to be confused with those of E. pyrophora. 



1. With E. gamophylla F.v.M. 



" The concrescence of the leaves by pairs in all stages of,growth occurs, so far as known, only in 

 E. 'perfoliata, if even in that rare and little known congener this coalescence should prove also 

 unexceptional. . . ." (" Eucalyptographia," under E. gamophjUa.) 



A discussion on such leaves will be found at pages 53 to 55 of Part XLII of the 

 present work. The number of species originally believed only to have connate leaves 

 during all stages of growth has been gradually reduced, until, apparently, E. perfoliata 

 alone remains, although in some, where a petiole has been found, it is exceedingly short. 

 As regards E. c/amophylla, see Plate 147, Part XXXV of the present work, it would 

 appear to differ from E. perjoliata in almost every other character.
