AFFINITIES. 



1. Witli E. cordata, Labill. 



The juvenile foliage is sometimes only maintained for one or two feet of 

 growth. In other localities it is maintained natil the plant is G to 8 feet, and is 

 always exactly like that of U. cordata. 



I will deal with the affinities of the two species when I come to E. co?'data. 



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



This species is like U. urnigera, one in which the juvenile foliage is nearly 

 orbicular, usually glaucous, and with crenulate margins. The buds and fruits are 

 very different. 



3. With E. corijmhosa, Sm. 



This species possesses an obvious resemblance to E. urnigera in the shape of 

 its fruit; the individual flowers are somewhat similar, but the inflorescence is less 

 corymbose. In other respects the resemblance appears to be less close. 



4 With E. cladoealijx, E.v.M. 



E. itrnigera is a species whose operculum is very much shorter than the calyx- 

 tube. This is accompanied by a peculiar curved shape, and also the diameter may 

 be larger than the calyx-tube at the junction (see fig. 14.b, Plate 80). Certain 

 members of the Corymbosro group, viz., E. maculata and eximia, have opercula 

 shorter than the calyx-tube, but the species arc very different in other respects. 



In E. cladocalyx, however, the size of the bud and the proportionate size of 

 operculum and calyx-tube are so similar to those of E. urnigera as to merit mention.

\n Twig with leaf ;iml frui*. i20 miles east of Beverley, \V. A. (W.D.Campbell). The Ilower is 3 inches 

 in diameicr in a dry state. The figure in the '■ Eucalyptograpliia" perhaps hardly shows 

 sufiiciently tlie crowded foliage. It certainly does not show the undulations of individual leaves.

 nor wing. 



3. Fruit. Plain north-east from New Norcia, W.A. (Dr. A. Morrison.) The fruit is larger and riper 

 than depicted in the " Eucalyptograpliia."

 markings (see p. 243), which arc fairly characteristic. Takalarup lload from Porongorups,
