A. cardiophylla was found on the sedimentary ridge previously 

 mentioned, and was not noticed in any other part of the countrj^ 

 described in these papers. It was flowering earl}'- in September, 

 and in general appearance, as well as size, much resembles A. 

 pubesceiis, R.Br., of the Parramatta district. 



A. rigens was found growing as trees up to 12 feet high with a 

 peculiar rough crinkled bark, and needle-shaped leaves generally 

 having straight points. The trees were covered with flowers earl}' 

 in September. 



A. ixiophylla (*?) was also flowering at the same time, but is a 

 smaller tree, with fairly smooth grey bark and ^Dale-coloured 

 leaves with numerous parallel veins. It was not seen previously, 

 and there is some doubt, in the absence of pods, as to its identity. 



A. diff'ormis was also first noticed here. This species, which is 

 common in the Wyalong district, somewhat resembles A. hakeoideSy 

 but has decidedly darker bark and foliage. The latter was 

 flowering in August and September, but young pods were found 

 on A. diff'ormis, showing that it must have flowered some time 

 previously. These trees, which average about 10 or 12 feet high, 

 often form scrubs extending over many acres, and sufticiently 

 thick to afford shelter for the nests of the Mallee Hen [Leipoa 

 ocellata). 



The Eucalypts noticed between Marsden and Wyalong were : — 

 E. rostraia (River Red Gum), E. Woollsiana (Black or N^arrow- 

 leaved Box) ; 10 m. E. sideroxylon (Ironbark), E. tereticoriiis, 

 v&v. dealbata (Gum); 8 m. E. co7iica (Apple IBox); 4 m. E. diimosa 

 (White Mallee), E. sideroxylon (Ironbark), E. jjopulifolia (Box, 

 scarce), E. Behriana, F.v.M., and a few trees of E. melliodora 

 (Yellow Box). 



The district around Wyalong is interesting to lovers of either 

 geology or botany. The formation in which the rich gold reefs 

 occur is granite, whereas many, though not all, of the reefing fields 

 in New South Wales are in sedimentary formations, ver}' often 

 Silurian slate, or, if in Plutonic, the rock is often other than 

 granite. The depth to which the rock has decomposed, and the 

 level at which water too salt for use is found, are among the
