E. pyriformis. — The colour of the filaments varies a good deal. Diels and 

 Pritzel speak of them as crimson, rose-coloured, and sulphur-coloured admixed on 

 the same group of plants. I have seen them crimson and yellow, and there seems to 

 be absolutely no botanical difference in the forms. White is an exceptional colour. 



E. pyriformis var. elongata. — Pink and white filaments, the former predominant. 



E. pyrophora var. polycarpa. —Filaments cream, sometimes pink. Broken Hill, 

 New South Wales. (A. Morris.) 



E. sideroxylon. — In New South Wales this tree of white or cream-coloured 

 filaments has very frecpiently pink and often crimson ones. In some seasons nearly 

 all the filaments appear to be highly coknired. It is the most showy of New South 

 Wales trees for that reason. 



E. Sieberiana. — On the cliffs at Eden, also Pipe Clay to Eden, New South Wales, 

 (J.H.M.). The lower parts of the filaments (especially before expansion) are purple, 

 giving the flowers an ornamental " eye " (ocellate), and this character is sometimes 

 useful in distinguishing it from plants with which it is associated. 



E. tereticornis. — Flowers on upper part of tree all pink. I have seen purple 

 filaments in this species in trees in the Sydney Botanic Gardens, Watson's Bay, Port 

 Jackson, and Casino, Richmond River, New South Wales. 



E. tetraptera Turcz. — Deep rose pink (Dauthenay's Plate 120, figs. 1-3.) The 

 filaments threw off the operculum within a week on 20th July, 1918. Another 

 description is deep cerise. I am in doubt as to whether I have seen " white " filaments 

 in the species. 



E. torquata. — Pink to crimson. I have seen them occasionally cream-coloured, 

 but pink appears to be the normal colour. 



E. viminalis. — Occasionally with purple bases of filaments. 



2. The following species I have not seen with white or cream-coloured filaments : 



E. miniata. — Orange to nearly scarlet. Much like E. phoenicea. 



E. phoenicea. — -Light orange to scarlet, and it is a gorgeous species. Both 

 belong to the tropics. 



3. Yellow or Yellowish. 



It is sometimes difficult to draw the line between indubitable yellows and 



greenish-yellows. Sometimes the creamy filaments come very close to the pale- or 



greenish-yellows. The question of colour is but one of the many branches of 

 Eucalyptology in which we Want to gather additional facts. 



E. erythrocorys.— Colour of filaments at first greenish-yellow (primrose-yellow), 

 and afterwards lemon- or golden-yellow (Dauthenay Plate 16, shades 2 and 3.) On 

 the whole a pure yellow. " Filaments sometimes purplish " (" Eucalyptographia.") 

 This tint is, however, but a supplementary tint, such as is very common amongst 

 filaments normally white.
