the young state, the most important of these being 2. perfoliata 
(North-western Australia), 2. risdoni (Tasmania), 2. sideroxylon 
(Ironbark, Victoria), #. wncinata and E. gamophylla (North and 
Central Australia). The latter, indeed, somewhat resembles Z. 
risdoni in the lanceolar semi-elliptical to half-ovate, or sometimes 
almost cordate, shape of the leaves. 
I have now very much pleasure in directing attention specially 
to two exhibits. These are—First, Z. risdonz, a fine specimen, 
with perfoliate or connate leaves ; with this specimen I am enabled 
to point out that 2. 7sdoni in its more matured state is never 
perfoliate ; its seed vessels are large. Specimen No, 2 is a very 
singular one, and it is to this that I wish to draw your attention. 
It is, as you may see, a small sub-alpine eucalypt, with perfoliate 
Zeaves. These being connate, or joined together, would seem to 
refer it to Z. risdont, but on comparing the two specimens shown 
it is at once seen that they are not at all allied, even in the young 
state, Z. risdoni showing a dark thick leaf, witha strong tendency 
to become lanceolate. No. 2 specimen, on the other hand, par- 
takes more of the characteristics of Z. cordata, but differs from it 
in the fact that the leaves of the latter are distinctly and zxvari- 
ably clasping at the base, whereas the former is a/zways perfoliate 
in young or old specimens. £. r/sdoni rarely or never retains the 
connate character of the leaves in its more advanced state, and 
herein lies a most important difference, and gives the assumption 
that the stranger is a new species. The veins are spreading, the 
marginal vein being removed from the edge, which is slightly 
crenulated and recurved. It is invariably found in a low, 
shrubby state, only a few feet high, in wet, marshy table-lands of 
high altitude. From dried specimens; showing the buds only, the 
disposition of the seed-vessels are in 3’s. The specimen in ques- 
tion was obtained about 10 miles from Parattah, on the main-line 
railway. It flowers in or about the month of March, and grows 
readily in water. The specimen in question grew well in the 
Exhibition Building and flowered there, but, unfortunately, they 
were destroyed by some passing visitor. The seed vessels are 
very small, about a line to a line and a half in diameter. From 
the perfoliate character of the specimen (£. visdonz) on the table, 
it is probably an Alpine form of this well-known tree, so numerous 
at Risdon, on the Derwent. 
The specimen No. 2 is quite distinct from £. cordata, in the 
size of the seed-vessels and also in the shape of them. I regret I 
have none to show at present, but I saw two on the plant when 
in the Exhibition. The shape of the leaves is different to that of 
E. cordata, being more orbicular, it differs also in the connate 
character of the foliage, though the venation is somewhat similar. 
As I have specimens of all the trees named in this paper, it is 
easy to note the different characteristics of the specimens shown, 
and I am of opinion that the new claimant to notice will be found 
to be a new species.
