THE VICTORIAN NATURALIST. 77 



pointed lid, larger fruits less downward attenuated and rather 

 long-valved, also in the foliage of the young seedlings. It 

 recedes mainly from E. viminalis in leaves with thinner venules 

 and more conspicuous oil-dots, in the flattened and also often 

 thicker and shorter peduncles, in the angular calyx-tube, in the 

 shape of the operculum, and again in the larger fruits with half- 

 enclosed valves of greater length and narrow rim. 



Mr. Bauerlen has sent from near the Clyde also specimens of 

 a Eucalypt, which he considers a hybrid between E. corymbosa 

 and E. maculata, in which case the characteristics of the former 

 are prevailing; the leaves however are generally narrower, the 

 operculum is double like that of E. maculata, and it separates by 

 a clear transverse line ; the wood also was found much lighter in 

 colour than that of the genuine E. corymbosa, and the bark 

 smooth on the upper portion of the stem as in E. maculata. 

 The flowering time proved later than that of the former ; as 

 many as 16 flowers occur in an umbel; the fruits are generally 

 not so long as those of E. corymbosa. 



Helipterum Troedelii. 



Annual, never tall ; upper part of the stems and any branches 

 beset with appressed lanuginous vestiture ; leaves small, copious, 

 from broad-linear to narrow-lanceolar, nearly flat, soon glabrous ; 

 headlets of flowers small, mostly crowded into terminal corymbs ; 

 peduncles very short or even some obliterated ; involucres al- 

 most hemi-ellipsoid, terminating in short white laminas ; outer in- 

 volucral bracts brownish or somewhat colourless, broadish, blunt, 

 glabrous; flowers 12-15; corollas only moderately widened up- 

 wards ; achenes beset with white silk-like vestiture, those of the 

 central flowers imperfectly developed ; pappus white, to about 

 one-third or nearly half its length quite tubular, thence extending 

 into 6-9 imperfectly pennular-plumous bristlets.

Erect or occasionally somewhat depressed. Height, so far as 

 known, to 7 inches. Stems usually several. Leaves %-Y\ inch 

 long, T /e inch broad or narrower ; involucre, irrespective of the 

 laminas, %~Yz inch long, the latter nearly half that length. 

 Corollas almost totally enclosed, about as long as the pappus. 



Somewhat similar to small forms of H. corymbiflorum, but 

 partly glabrous ; allied also to H. strictum, but the leaves much 

 narrower and the peduncles very short ; differing also widely from 

 both and indeed from most congeners in the paucity of the brist- 

 lets of the pappus, which moreover is more extensively tubular 

 than that of any other species. The plant shows some external 

 resemblance also to Helichrysum semifertile ; but the pappus is 

 very different, and so the indument of the achenes.
