Mueller's favourite words concerning the bending of the filaments are 

 " inflexed " (or incurved) " while in bud." They have not been repeated in the following 

 notes on species : — 



E. clavigera. — Deeply inflexed. 



E. erythronema. — Sharply inflexed. 



E. gracilis. — Strongly inflexed. 



E. salubris. — Rather sharply bent inward. 



E. uneinata.— Filaments suddenly and sharply inflected, but not flexuous. 



E. rudis, E. redtmca.— Inflexed, except some of the outermost, 



E. microtheca.— Inflexed, except some of the outermost. Stamens very short. 



E. siderophloia, E. salmonopMoia. —Outer filaments not inflexed. 



E. pyriformis.— The outer only incurved at the apex. 



E. gomphocephala.— Outer stamens almost straight in bud, inner stamens more or less inflexed, 



E. Oldjieldii.— Not inflexed, inner stamens only slightly bent inward while in bud. 



E. macrocarpa. — The inner much inflexed. 



E. santalifolia. — Filaments ascendant, not inflexed. 



E. oleosa. — Flexuose and inflexed. 



E. Hoicittiana.— Flexuose and towards the summit bent inwards. 



E. ficifolia— Inflexed and dependent, 



E. cornuta. — Xot inflexed. 



E. obcordata. E. occidentalis. — Straight, 



E. marginata.— Not bent back, but the figure shows the inner ones inflexed. 



Xaudin in 1891 noted that the shape of the operculum determines the bending., 

 or otherwise, of the filament. 



" When it is short, which is the ordinary case, the stamens, always very numerous, and pressing 

 one against.the other, bend themselves back towards the centre of the flower; they remain straight 

 when the very elongated operculum leaves them a free field; for example in E. cornuta and E. Lehnanni." 

 (Xaudin, Mem. II, 13.) 



I have neither figured nor described the inflexion of the stamens, as Mueller 

 has done, as it seemed to me dependent on the length of the operculum, as already 

 stated. 



Crimpiness in Cornutse. 



The original description of E. Lehnanni says, " Filaments quadrangular 

 filiform." (Schauer.) 



Bentham {ante, p. 195), speaks of the Cornutse having " flexuose " filaments. 



Mueller, in '"' Eucalyptographia," under E. cornuta, says, " always cmite straight 

 in bud, except slight flexuosities, as noted by the author in 1865," and, under 



E. occidentalis. '' Filaments thicker than those of very many other congeners, 

 rather bristly than capillary . . . dotted with oil glands." 



' We have in E. macranclra not only angular filaments (as occur in most of the 

 Cornutse), but these are crinkly or bent, and in each bend is an oil-gland or a resinous 

 mass. In filaments which are truly thread-like, where there are glands, they stand 

 out like tubercles {e.g., E. megacarjia, fig. 66, Plate 78) ; but in the Cornuta?, while 

 studding the surface of the filament, they do not appear to project beyond its 

 outline." (This work, Part XXXVI, p. 153.)
