1. E, triantlia. Link. Following is the original description: — 



222. E. triantha. Fol. oblongis basi inaequalibus subattenuatis acuminatis subfalcatis, pedunculis 

 axillaribus trifloris, floribus sessilibus. 



Hab. in Australia. Glaberrima uti reliquae. Fol. petiolo 5-6" longo. lamina 3 longa 10" lata 

 non punctata, subtus nervis parallelis omnibus ante marginem connexis. Ped 6" longi. Operculum ? 

 (Link, in Enumeratio plantarum horti rejii botanici Berolensis, ii, 30, 1822). 



Bentham (B.Fl. iii, 200) rejects the name triantha on the ground that the plant 

 is too imperfectly described. 



Mueller (Eucalyptographia) rejects the name triantha on the ground that it is 

 unsuitable, the three-flowered form being an exception. Such a reason is not valid. 

 However, in his Second Census, he suppresses acmenioides and adopts the name triantha. 



I have only seen that fragment of the type of E. triantha which I have figured 

 in Plate 42. As I am not absolutely certain of the identity of E. acmenioides and 

 E. triantha, I prefer not to adopt E. triantha at present. The name is 21 years older 

 than E. acmenioides, and I shall not hesitate to restore E. triantha if, in my opinion, 

 additional evidence warrants it. 



In communicating to me a portion of the type of E. triantha, the Director of the 

 Royal Botanic Garden of Berlin informed me that no specific locality was given by 

 the collector. 



2. E. carnea, R. T. Baker. 



Described in Proc. Linn. Soc. N.S.W., xxxi, 303 (1906). 



The abstract of the description furnished by the author is as follows: — 



" E. carnea is a typical forest Stringybark, with a pinkish or flesh-coloured, hard, durable timber. 

 The mature fruits difier very little in shape and size from those of E. acmenioides, Schau., but otherwise 

 these two species can be differentiated by their leaves, timber, and oil. This latter constituent is of some 

 chemical and industrial importance, as it contains, besides a dextro-rotatory pinene and eucalyptol, an 

 acetic acid ester. Only a small quantity of free acetic acid was found in the crude oil, but the ester split 

 off acid on distilling the oil under atmospheric pressure. Systematically the species should be placed with 

 the Stringybarks, and in sequence with E. nvjra, R.T.B., and E. acmenioides, Sch." 



The author points out that he had previously confused it with E. umbra {q.v.). 

 Mr. Baker's description is accompanied by a plate, and figure 8, Plate '42 of the present 

 work depicts the plant. 



Mr. Baker only records it from the Richmond River, N.S.W., and draws 

 attention to the pink colour of the timber, which is stated to be of diagnostic 

 value. 



It seems to me that this tree cannot be separated from E. acmenioides. 



Both E. carnea and E. acmenioides have pale underside leaves, much more 

 evident in the case of the latter. Both lose it more or less with very old leaves. 



As to the dimensions of the juvenile foliage, I have Mr. Baker's type before me, 

 and A. Murphy's " White Mahogany, from the low flat country, Woy Woy " (the tree
