diameter of five feet. The wood though more easily worked than 

 that of many Eucalyj^ts, is not considered durable, and is more 

 valued for fuel than any other purpose. According to experiments 

 directed by Baron Mueller, the bark of this tree yields 8-3 per 

 cent, of Kino-tannic acid and can be converted into packing paper; 

 whilst it was found, from leaves which were forwarded from 

 Parramatta, that the yield of 100 lbs. of them is between three 

 and four ounces of volatile oil, remarkable for imparting an 

 indelible transparent stain to paper, and giving a clear flame 

 somewhat inferior to kerosene in intensity. The specific gravity 

 of this oil is 0-940, and the boiling points between 380° and 420° 

 respectively. ^. longifolia, as the Baron remarks, is not easily 

 mistaken for any of its congeners. It seems to attain its greatest 

 size in New South Wales, but it does not extend far inland. 



5. E. largijlorens (F.v.M.), seems to be the E. hicolor of A. 

 Cunningham, and is known to workmen as ''Bastard Box," 

 '' Yellow Box," and '' Gunitop." It is a very large tree growing 

 in low or swampy places to the height of 150 feet. In its young 

 state, it resembles the common Box, but, as the tree advances in 

 age, it loses its half -barked character and resembles the Grey 

 Gum, though frequently retaining some fibrous bark on the butt. 

 The specific name largijlorens is very appropriate, for, although 

 the tree does not appear to flower regularly, the top of it is 

 sometimes one mass of flowers. In the larger trees, the wood is 

 very tough and durable, being adapted for fencing, shafts, cogs, 

 and rough buildings, but they are frequently hollow and decayed 

 at heart. The flowers and leaves of this species resemble some 

 forms of JS. crehra, but, whilst the two species belong to dift'erent 

 sections under the cortical system, they are also separated by the 

 venation of the leaves and the shape of the anthers. It would 

 appear that E. largijlorens has a very wide range, and it is 

 remarkable for extending far into the interior, though somewhat 

 dwarfed in grovrth, and occasionally with red filaments. For the 

 determination of this species we are much indebted to Baron
