196 NOTES OS THE EUCALYPTS OF THE BLUE MOUNTAINS, 



that E. Co/isiclenia7ia is possibly a hybrid between the two species 

 named). 



F. jjiperita fruits in large masses or bunches, while E. Con- 

 sideniana is a comparatively shy fruiter. The fruits resemble 

 those of E. Sieheriana a good deal. 



The bark of E. Consideniana is nearest that of E. piperita. In 

 small trees, E. Consideniana may have bark as smooth as piper'ita, 

 which is really quite smooth, fibrous in large trees. The Blue 

 Mountains trees of E. Sieheriana have not, as a rule, the furrowed, 

 Ironbark-looking bark of the typical form, and, speaking in 

 general terms, the bark of E. Consideniana presents some 

 resemblance also to the bark of the trees of E. Sieheriana, with 

 which it is associated. 



13. E. STRICTA, Sieb. 



Our first specimen was observed just past Faulconbridge 

 Station, and was 9 inches in diameter with a height of 20 feet. 

 It is worthy of remark that the young leaves contain Caoutchouc, 

 In favourable localities this species, usuall}' a shrubby plant, 

 grows taller, with fewer flowers and coarser foliaofe. The coarse- 

 ness of the species appears to be a matter of good soil and shelter. 

 The opercula are often red in fresh specimens. 



The seedling leaves are lanceolate, erect, equally green (bright 

 or sap-green) on both sides. The oil dots on the juvenile foliage 

 are well marked. The young twigs are reddish, with tubercles 

 of a darker colour. 



14. E. viRGATA, Sieb., var. altior, Deane & Maiden {E. oreades, 

 R. T. Baker). 



Found in the valleys or on the taluses of the hills from Spring- 

 wood higher. Its precise range is a matter for observation. 



Young seedlings remind one of those of E. Sieheriayia a good 

 deal. They are medium lanceolate, bluish-green, equally green 

 on both sides. Decussate at first, after two or three pairs they 

 lose their horizontal character. At length they are more or less 

 undulate and pendulous.
