NOTES ON EUCALYPTUS. 319 



obtusa, pallida saepa glauca, 8-12 cm. longa, 6-7 cm. lata. 

 Venae patentes, venis principis fere parallelibus, margine crassata. 

 Folia matura petiolata, alternata, falcata, petiolis 2 cm. longis, 

 foliis ad 16 cm. longis et 4 cm. latis. Alabastri, pedunculis bre- 

 vibus leniter planis, floribus sessilibus vel fere sessilibus, 4-7 

 capitulo. Operculum hemisphsericum circiter dimidio cupula sub- 

 angulare aequilongum. Antherae aperientes in fissuris parallelibus, 

 versatiles, dorso glandula magna. Fructus non vidimus. 



"Amongst the tallest of the tropical species, occasionally 

 reaching a height of 80 feet." 



Particulars as to habit, bark and timber not available. 



Juvenile leaves. — The following description has been 

 drawn up from specimens in the flowering (or rather plump 

 bud) stage. They represent, as far as we have them at 

 present, the juvenile leaf stage; at the same time, they 

 are mature to the extent that they are contemporaneous 

 with the inflorescence. 



Opposite, almost stem-clasping, the petioles being very 

 short or absent ; very broadly lanceolate to nearly ovate, 

 cordate at the base, apex blunt-pointed, margin sometimes 

 undulate, pale coloured, or entirely glabrous. Length 8 — 

 12 cm., width 6-7 cm. 



Venation spreading, the principal veins roughly parallel, 

 and making an angle of approximately 60° with the midrib. 

 The margin thickened, the intramarginal vein well removed 

 from the edge, the venation distinct, particularly on the 

 lower surface. 



Mature leaves. — (Petiolate, alternate, lanceolate, falcate, 

 with petioles of 2 cm., and leaves up to 16 cm. long and 

 4 cm. wide. Venation distinct, the foliage pale-coloured 

 and glabrous and the two surfaces scarcely to be dis- 

 tinguished from each other.)
