3. With E. redunea Schauer. 



A. Note on E. redunea var oxymitra Diels. 

 Following is a translation of some remarks by Drs. Diel and Pritzel : — 



" Tlie Series Cornutae of Bentham, with stamens erect in the bud, is represented in Western Australia 

 by aberrant forms. Sometimes it shows transit to some other series. We have observed, for example, 

 near the Phillips River, a specimen of a shrubby form very similar to the narrow-leaved forms of E. occiden- 

 talis, but the stamens are inflexed, and show an affinity to E. redunea." (D. 4,885.) (Enrjler's Jahrb. 

 XXXV, 442.) 



This is figured by me at Plate 141, fig. 5, Part XXXIV, as a form of E. redunea, 

 as I found the filaments inflexed like those of E. redunea, and for that and other reasons 

 I removed it from E. occidentalis var. oxymitra, and constituted it a variety' of the same 

 name under E. redunea. 



B. " E. occidentalis bears likewise some resemblance to E. redunea, nothwitstanding the sectionally 

 different position of the two species in the anthereal system, but the bark of E. redunea is altogether smooth 

 and imparts on friction pf its surface a white colouration (this is wTong as regards the bark; E. acenh //-.s is 

 referred to, see p. 10, Part XXXIV), the flowers are smaller and seated on shorter stalklets, the lid is acutely 

 2>ointed, proportionately shorter, and contracted gradually from a not dilated base, the filaments are thinner, 

 shorter, less angular, more whitish and inflexed while in bud ; the fruits are smaller and slightly contracted 

 at the orifice, while their valves are more enclosed, the fertile seeds are smaller, and their testa of lighter 

 colour and smooth." (" Eucalyptographia," under E. occidentalis.) 



Let us compare Plates 140 and 141, Part XXXI V, with Plate 148 in the present 

 Part. Mueller has contrasted the two species very carefully. Speaking generally, the 

 opercula of E. redunea are long and acute, as compared with the shorter and more 

 cylindrical opercula of E . occidentalis . The fruits of E . redunea are smaller, and, although 

 very occasionally somewhat campanula te, that is rare. The form of E. redunea one 

 usually sees is an undoubted White Gum, while E. occidentalis is more umbrageous, 

 and with a roughish bark. 



4. With E. comuta Labill. 



In other words, what are the differences between the true Yate (E. cornuta) and 

 the Flat-topped Yate (E. occidentalis). Leaving out the Mallet or smooth-barked tree 

 (the variety astringens), I have already described the appearance of the tree and bark of 

 E. occidentalis and of E. cornuta as Part XXXIV, p. 103. An old Yate has a dark, 

 fissured bark, reminding an easterner of an Ironbark. There is apparently more 

 crenulation in the juvenile leaves of E. cornuta than in E. occidentalis. At the same 

 time, there is more or less crenulation in leaves of the Cornutro. 



In E. cornuta the flowers are sessile or nearly so, with longer and more curved 

 opercula, with the lower part of the fruit less campanulate, and the valves drawn out 

 to exceptionally long points. 



Bentham (B. Fl. iii, 195) states the principal characters of E. occidentalis thus : — 

 Leaves of E. comu/n. 

 Peduncles flattened. 



Flowers and fruit distinctly pedicellate. 

 Ovary and carjsule convex; or conical at the top. 

 Fruit tirccolate; valves acuminate, protruding when open
