(3.) Lanceolate leaves, large fruits. " Very clean white Gum." Toot of 

 Darling Eange, Kelmscott, near Perth (Dr. J. B. Cleland). Figured at 4, Plate 

 74. It seems to he- a large fruited form of Sargent's No. 266. 



(4.) A form collected hy Dr. A. Morrison, at Mt. Saddleback, Marradong, 

 "Williams District, is remarkable for its conical operculum. 



It is figured at 10, Plate 74. It has dull coloured foliage, and, except for 

 the length of the operculum, appears to be typical var. Drummondii. 



(5.) The following interesting form was collected by me at 66j mile-post, 

 Pindar, Murchison Line. 



Many-stemmed, 10-15 or 20 feet. Tough wood. Peculiar bark, falling off 

 in narrow longitudinal pieces, giving it a striped appearance. The indurated stems 

 are 3 inches in diameter. Several clumps seen. 



Very yellow buds with hemispherical operculum and absolutely no mucro. 

 Operculum, which is distinctly smaller than the calyx, affording one of the best 

 examples I remember of the " egg-in-egg-cup " bud. Leaves greenish-yellow, dull 

 coloured. The material I have, is figured at 11, Plate 74. 



Now, 1, 2, 3 are alike in leaf (lanceolate, bright green, and showing venation). 

 4 and 5 are broader and duller, the venation, except the midrib, scarcely discernible. 



Nos. 1 and 2 are alike in buds (I have no buds of 3) and they strongly 

 resemble those of No. 5. 



Western Australians should examine E. Oldjieldii and its forms in the bush, 

 and should particularly collect juvenile foliage while still in the opposite stage. 

 Examination of these will probably settle the matter of the relation of E. Oldjieldii 

 to its varieties and whether we have a second species. 



AFFINITIES. 



Mueller ("Eucalyptographia") says: — 



The leaves and anthers bring it into the vicinity of E. oleosa and E. pachyphylla, while the stamens, 

 as regards their early position, indicate an affinity to E. gomphocephala and E. pachyloma. 



We will take the species referred to in detiil. 



1. E oleosa, F.v.M. 



While the anthers of E. Oldjieldii and E. oleosa resemble each other a good 

 deal, comparison with Plates 65 and 66 shows that the similarities of the two species 

 in most characters is not close. 



2. E. pachyphylla, E.v.M. (E. pyriformis, Turcz., var. minor). 



I have some notes on this variety at page 230 below. The fruits, &c, are figured 

 at figs. 5-7, Plate 75 of the present Part. The fruits of E pyriformis, var. minor, are 

 sessile or stalked ; so are those of E Oldfieldii ; the rim of var. minor is concave and 

 not convex, whde there are ribs in var. minor. 



There is some similarity in the anthers. See under E. pyriformis, page 229
