township of Robe, which is the most southerly South Australian locality known to me, 

 and the nearest to the only recorded Victorian locality (Cape Nelson). I have specimens 

 of E. diversifolia from Robe (C. D. Black through J. M. Black). 



Figures 9. 10, 11 of Plate 36 are E. pachyloma Benth. so that it is not necessary 

 to add much. 



RANGE. 



In the " Eucalyptographia," under E. santalifolia the following localities really 

 belong to E. pachyloma. It is confined to Western Australia. 



In sandy desert country, as also in scrubby valleys or on arid ridges near King 

 George's Sound (Drummond): on the Williams River (Webb); near the Kalgan River 

 (Oldfield); at the base of the Stirling Ranges (F.v.M.). 



I have seen the following specimens : — 



Western Australia. — Drummond' s No. 64; Stirling Range (Mueller); west from 

 Yetemerup, N. side of Stirling Range (A Morrison); King George's Sound (? Webb). 

 I collected specimens from the Kalgan Plains, near the foot of the Stirling Range. 



AFFINITIES. 



1. With E. diversifolia Bonpl. 



E. pachyloma is nearest to this species, and is a spindly sand-plain gum, not 

 known to attain tree-size. Its leaves are thick-coriaceous, much more coriaceous than 

 those of E. diversifolia. Its juvenile leaves are narrow-lanceolate, and although occa- 

 sionally broader, they are shortly pedicellate and never as broad, nor as stem-clasping, 

 nor as thin as those of E. diversifolia. What E. pachyloma is can be seen in the excellent 

 plate of that species (under the name of E. santalifolia) in the "Eucalyptographia," 

 and figures 9-11 of Plate 36 of the present work, stated in the legend of Part vii, p. 205, 

 to be E. pachyloma, although at that time included by me under E. diversifolia. 



2. With E. Oldfieldii F.v.M. 



" Fruit sessile, depressed-globose, 7 to 8 lines diameter, with the very thick, broad convex and raised 

 rim of E. Oldfieldii, but without any depressed centre, the capsule not sunk, and the small valves protruding 

 as in E. rostrata." (Original description of E. pachyloma.) Bentham placed it next to E. Oldfieldii F.v.M. 



" Although Bentham puts his E. pachyloma in the series of Normales (Parallelantherse), it belongs 

 in reality to the Renanthera;, notwithstanding the lesser divergence of the anther-cells, because the anthers 

 are heart-shaped, not at all ovate. Their slits are convergent and fully joined at the summit. The connective 

 is obliterated in front, so as to render the anther-cells then completely contiguous, and the seeds are nearly 

 uniform in size, which all is quite characteristic of the Renantherse. Indeed, E. pachyloma seems reducible 

 to the true shrubby E. santalifolia, having precisely the same anthers also " (" Eucalyptographia," under 

 E. Oldfieldii).
