416 ON TWO NEW SPECIES OF EUCxVLYPTUS, 



from the leaves of which is extracted (1) the dye myrticolorin ; 

 (2) an oil, very rich in the new solid camphor or stearoptene 

 endpsmol, and also cineol. These bodies are entirely absent from 

 the leaves of this particular Eucalypt, and the oil is almost 

 entirely composed of Isevo-rotatory pinene. 



The presence of pinene of course allies it with the other species 

 described in this paper, whilst the optical characters remove it 

 from that species. It differs from E. capitellata and E. eicyenioides 

 in the shape of its fruits, its bark, buds, and leaves, and the 

 chemical constituents of its oil, but yet it is a " Stringybark," 

 and the timber shows affinities with that group of Eucalypts, while 

 the hemispherical base and size of the fruits are not unlike those 

 of E. capitellata. In botanical sequence it may be placed after 

 E. capitellata. 



It is distinguishable from E. ohliqua hj its fruits and timber 

 as well as its oil, but resembles that species somewhat in the 

 shape of its leaves and buds. 



It differs from E dextropinea of this paper in its fruits never 

 having a countersunk rim, the superior quality of its timber, and 

 the presence of a dextro-rotatory pinene in its essential oil. The 

 leaves and buds of the two are identical. 



The oblique leaves and immature fruits led me at one time to 

 consider this species as E. obliqua, L'Her., and I so recorded it 

 (Proc. Linn. Soc. N. S. Wales, Vol x. 2nd Series, 1896). 



I have to tender my best thanks to Mr. James Dawson, L.S., 

 of Rylstone, for his great kindness in placing every facility in 

 my way for obtaining complete specimens of " Silver-Top Stringy- 

 bark," including specimens of the timber and of leaves for oil 

 distillation. 



E. L.EVOPINEA, var. MINOR. 



A tree with the same characters as the type, except that the 

 buds are sessile and the fruits smaller. The oil, however, is white 

 and thin, instead of a reddish colour as in the former species; the 

 absence of colour is due to the presence of phellandrene. Other- 

 wise the oil is identical in its chemical composition with that of
