E. setosa Schauer. — Has bracts and bractoles. For bracts, see fig. la, and 

 bracteoles, figs, la and 4fr ; all in Plate 158. 



E. SMrleyi Maiden. — The marks of the enveloping bracts are clearly seen in this 

 species. 



E. Sieberiana F.v.M. — I have seen enveloping bracts in this species in the Bine 

 Mountains, New South Wales. 



E. stricta Sieb. — I have seen an enveloping bract in this species at Mount Victoria, 

 New South Wales. 



E. tetragona F.v.M. — Bracts of the umbel two, semifoliaceous, nairow lanceolate 

 to concave, keeled. Near Esperance, Western Australia. 



E. letrodonta F.v.M.- — Bracts at the summit of the flower- stalk boat-shaped, 

 lanceolar. (" Eucalyptographia.") 



E. virgata Sieb.-- See fig. 6/, Plate 44. 



(b) Bracteoles. 



Bentham (already cpioted) appears to me to be the only botanist who refers 

 to bracteoles in addition to bracts. From what follows, and I will offer some figures 

 in due course, I make the following observations : — 



1. There may be a bracteole for each bud, as well as bracts enveloping the whole 



umbel. 



2. The occurrence of bracteoles appears to be confined to the Corymbosee. 



3. There may be six bracteoles alternating with the six bracts of an umbel. 



4. The bracts appear to be broader and slightly shorter than the bracteoles, but 



that may be only apparent; the bracteoles appear to wilt more readily. 



Doubtless botanists will give special attention to both bracts and bracteoles 

 in the future, and may be able to offer useful generalisations. 



E. calophylla R. Br. — Mr. Blakely brought me (31st July. 1918) specimens 

 (cultivated, of course) from the Botanic Gardens, Sydney, that I cannot differentiate 

 from the bracts and bracteoles of E. ficifolia, to be immediately referred to. In May, 

 1919, on further examining some fresh specimens, I noted that in E. calophylla each 

 somewhat subulate bracteole persists until the bud is on the point of opening. See 

 also fig. 2, Plate 176. 



E. fwifola F.v.M. — From a tree cultivated in the Botanic Gardens, Sydney, 

 near the foot of the Victoria Lodge, Messrs. W. F. Blakely and J. P. Shclton brought 

 me, on 26th July, 1918, specimens showing both bracts and bracteoles, which Miss 

 Flockton has figured, and her drawings will be reproduced in due course.
