alone. At the same time, other kinos tend to this colour, and it 

 may be that a regular gradation of kino-colours will be found, as 

 our knowledge of authentic species of these substances increases. 

 It is also worthy of note that E. microcorys is the only* kino of 

 the turbid group belonging to the Renantherese. Its resemblance 

 to that of E. maculata is very marked, and it is as different as 

 possible from any other Eenantherous kino. It is worth 

 enquiring of what value this observation may be, as bearing upon 

 the affinities of E. microcorys. 



The order in which kinos belonging to this group are placed is 

 only provisional, as at present under 30 species belong to the 

 group as the result of absolute experiment, and very much more 

 material requires to be accumulated, in order that one may be in 

 a position to subdivide it with any degree of finality. It promises 

 to be the largest of the kino groups, and while already I can 

 predict a number of species which will fall into it, I confine 

 myself strictly to facts. Following are the species referred to in 

 this paper : — 



E. hemiphloia 



„ ,, var. albens = E. albens 



E. odorata 



E. luelliodora 



E.fasciculosa (non E. panicidata, Sm.) 



E. corynocalyx 



E. leucoxylon (non E. sideroxylon, A.Cunn.) 



E. corimta 



E. rostrata 



E. viminalis 



E. Stitartiana 



E. Maideni 



E. Gunnii 



E. goniocalyx 



E. Bauerleni 



* The only species of the Renantherese I have not examined is E. 

 acmenoides ; see p. 606, Vol. iv., Series 2.
