AFFINITIES. 



1. With E. eordata, Labill. 



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

 growth. In other localities it is maintained until the plant is 6 to 8 feet, and is 

 always exactly like that of E. eordata. 



I will deal "with the affinities of the two species when I come to E. eordata. 



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



This species is like E. umigera, 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. corymbosa, Sin. 



This species possesses an obvious resemblance to E. umigera 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. eladocalyx, F.v.M. 



E. umigera 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. 14b, Plate 80). Certain 

 members of the Coryrnbosae group, viz., E. maculata and eximia, have opercnla 

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



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

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



Explanation of Plates. 



PLATE 77. 



Eucalyptus macrocarpa, Hook. 



Is. Twig with leaf and frui\ 20 miles east of Beverley, W.A. (W. D. Campbell). The flower is 3 inches 

 in diame'er in a diy btate. The figure in the '• Eucal^ptograpbia" perhaps hardly shows 

 sufficiently the crowded foliage. It certainly dees not show the undulations of individual leaves. 

 16, front and back views of anther. The anther has a somewhat remarkable shape. 



2. Bud received from Miss Moore, of Perth, W.A. Locality not stated. This bud shows neither angle 



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 " Eucalyptographia." 



Eucalyptus Preissiana, Schauer. 



4a and ib. Two pairs of juvenile leaves; 4c, double opercula (rather shrivelled). 4a .shows the insect 

 markings (see p. 243), which are fairly characteristic. Takalarup Road from Porongorups,
