3. With. E. microtheea F.v.M. 



See Vol. ii, p. 51, and Plate 52. Though, with larger fruits, they are of the 

 E. Raveretiana type, and therefore different from E. Howittiana. The buds are 

 pedicellate and of a different shape, the anthers are different. 



4. With E. populifolia Hook. 



See Vol. i, p. 339, and Plate 48. As a rule, the foliage of E. populifolia is broader 

 than that of E. Howittiana and even nearly circular, and always shining. The venation 

 of the narrow-leaved forms is different to that of E. Howittiana. The two species 

 belong to different anthereal groups, the fruits of E. populifolia are pedicellate and the 

 rims different. 



5. With E. Raveretiana F.v.M. 



" E. Howittiana comes in some respects near E. Raveretiana, sharing in the remarkable smallness 

 and also much in the form of the flowers ; but it differs significantly in more rigid and often broader leaves 

 with darker and shining upper page, and with hardly perceptible oil-glands ; furthermore, flower-stalklets 

 are not developed, or only to a trifling extent, the calyx-tube is not so short, nor are the fruit-valves extruded. 

 With no other species is it closely connected." (Eucalyptographia.) This is Mueller's judgment on such 

 evidence as was available. 



See Vol. ii, Plate 53 of the present work. I have not seen juvenile foliage of 

 E. Howittiana; it will probably prove to be broadish. The buds are much larger in 

 E. Howittiana, and the anthers sharply separate the two species. The fruits of the 

 two species are very different. 



6. With E. stellulata Sieb. 



. . . " the shape of the calyx reminds of that of E. stellulata " (" Eucalypto- 

 graphia " under E. Howittiana). 



See Vol. i, p. 127, Plate 25 of this work. The inflorescence in E. stellulata is 

 axillary, with sessile umbels ; in E. Howittiana the inflorescence is in panicles with 

 peduncles and no pedicels. The two species both lack pedicels, giving their buds a 

 stellate aspect, particularly in E. stellulata. There seems to be no other similarity. 

 The anthers of E. stellulata are kidney-shaped, and the venation of the leaves straight. 



7. With E. Cloeziana F.v.M. 



(Fohage) — " which is not unlike that of E. Cloeziana, but the flowers of the last are umbellate, 

 therefore not strictly capitate in the panicles, the calyces are remarkably open, not indicating a subsequent 

 fruit much closed like that of E. Howittiana, while the young valves are inserted much below the orifice ; 

 ripe fruits of E. Cloeziana remain still unknown." (Original description.) 



" The fohage resembles that oi E. Cloeziana, but is much wanting in oil-dots ; the lid is, however, 

 very different, and the fruits are much contracted towards the summit." (Eucalyptographia.) 



Vol. ii, Plates 63 and 64 of the present work may be turned to. 



The two species belong to the same anthereal group, but the buds of E. Howittiana 

 have no pedicels. The fruits of E. Cloeziana are larger, and the valves are usually 

 more exsert, but the shape of the fruit is not very dissimilar to that of E. Howittiana, 

 It is nearest to E. Howittiana of any species compared with it so far.
