106 THE EUCALYPTS OF GIPPSLAND. 



On the great Divide itself E. sieberiana (a) ends abruptly at 3000ft., and E. 

 sieberiana {b) commences at 3500ft., here also grows E. obliqua to great size, but 

 ceases at 3100ft. at the descent into the Upper Livingtone Creek, where the mountain 

 types of Eucalypts commence, viz., E. gunnii (b), E. stellulata, E. paucifiora, E. 

 viminalis, and E. amygdalina. ♦ 



In descending from the Omeo plateau towards Tongio, T observed that E. 

 hemiphloia, variety albens, commences at 2500ft. This Eucalypt grows preferen- 

 tially upon the Plutonic and Metamorphic formations of the dry valleys of Tongio 

 and Ensay, the Upper Snowy (in Victoria), and of the Deddick and Tubbut Rivers. 

 In the descent from Omeo one finds E. melliodora at 2000ft. In passing from the 

 deep valleys of Ensay to the coast ranges, which may be regarded as commencing at 

 Mount Elizabeth, I observed that E. hemiphloia ceased at 1000ft. at Ensay, but this 

 elevation must probably be decreased considerably, as I believe this type grows on the 

 Tambo at Numlamungie, approximately 700ft. above sea level. The same remarks 

 apply to E. stellulata, on the summit of Fainting Range. I have noticed that E. 

 polyanthema, E. goniocalyx, E. piperita, and E. obhqua re-appear at their upper limit 

 in this locality, and it is about here that the littoral types touch and intermingle 

 with the mountain forms. It is here to be noted, as at other places to which I have 

 referred, that it is the lowland types which slightly cross the limit set them by the 

 summit of the cool mountains, and descend to some little extent in the warmer slopes, 

 rather than the mountain types, which descend the moist southern side. 



At Noyang, on the Tambo Valley road, there occurs a tract of Plutonic and 

 Metamorphic rocks, and here there is, to a certain extent, a re-appearance of the 

 sub-alpine types intermingling with a greater number of the lowland Eucalypts. 



Further down the road E. muelleriana appears, growing on the Silurian for- 

 mations from the upper limit of the Tertiary marine beds at 700ft. to 1300ft. 

 I observed only one or two scattered examples growing in the forest of E. piperita on 

 the Tertiary sands near Monkey Creek. 



I might instance other examples in the mountain country, in the sources of the 

 Buchan River — at Murrendel, at Woolgulmerang, and at Bonang, but the above will 

 suffice, and my observations in these localities, although made with sufficient care to 

 satisfy me as to the general results, want the precision which I have endeavoured to 

 give to the cases which I have noted. My notes on the eastward of the Snowy River, 

 in Croajingolong, were made many years ago, and fall into line with those I have 

 given, but as they were less precise even than those made between the Tambo and 

 Snowy Rivers, I prefer not to rely upon them. 



The observations which I have now recorded as to the distribution in the
