Tall ; leaves scattered, on long stalks, lanceolar- or rhomboid-oval, gradually mucli elongated 

 into the narrow apex, equally pale-green on both sides, not shining ; oil-dots much concealed ; 

 lateral veins rather numerous, very spreading, circumferential vein more or less distant from the 

 edge ; umbels axHlary or lateral, on a comparatively short somewhat angular stalk, with seven or 

 fewer flowers ; stalklets about as long as the calyx or somewhat shorter ; tube of the calyx 

 semiovate-hemispherical, hardly as loiig as the semiglobular short-joointed smooth lid ; stamens all 

 fertile, inflexed before expansion ; anthers cuneate- or oval-oblong, opening by parallel slits ; 

 stigma not dUated ; fruits topshwped-hemispherical, rather small, 3-4-celled, slightly or not angular ; 

 rim flat ; valees exserted ; placental axis not twice as long as broad, deltoid ; seeds without 

 aj)pendage. 



In Timor. 



According- to Blume's description some leaves occur occasionally blunt and the lid conical. 

 As in Malayan language it is along with Melaleuca Leucadendron called Cajuputi, it may perhaps 

 furnish a j)ortion of the medicinal oil of that name. The leaves of specimens, gathered by the 

 meritorious Mr. Teysmann of the Botanic Garden of Buitenzorg and kindly communicated by 

 Dr. Scheffer, are of a thickly chartaceous but not leathery consistence and attain a breadth of 3 

 inches. The umbels, while in a very young state, are enveloped in a conical bract. Neither 

 expanded flowers, nor matured seeds of Timor-specimens, were available for examination at this 

 opportunity. From the material before me, it remains doubtful, whether really E. tectifica can 

 be ideutified with this Timor-species ; the bark of the Carpentaria-tree being persistent and rough 

 as well on the branches as on the stem, though it is certainly also pale outside and is used by the 

 Aborigines there for constructing the rude roofs of their sleeping places ; the leaf-stalks are 

 shorter, the leaves generally narrower, the umbels sometimes short-paniculate and terminal. 



E. platyijhylla (F. v. M., in the Journal of Proceedings of the Linnean Society iii. 93) 

 approaches closely to E. alba ; the leaves are mostly broader, the lid is generally shorter and 

 blunt and the valves less exserted ; its foliage sheds for short periods almost entirely. The range 

 of variability of these trees remains yet to be further ascertained by extended field-researches. 



The number of Extra- Australian species of Eucalyptus is extremely limited, so far as hitherto 

 known, although additional congeners may perhaps yet be obtained from New Guinea, and even 

 there possibly from alpine regions. With certainty we know from localities beyond Australia 

 hitherto only E. alba, E. Moluccana (Roxburgh flora Indica ii. 498), E. Decaisneana (Blume, 

 Museum botanicum Lugduno-Batavum i. 83), also from Timor, and E. Papuana (F. v. M., De- 

 scriptive Notes on Papuan Plants i. 8), which bears close aflrnity to E. ckvigura. The existence 

 of at least one more species in fiouth-Eastern New Guinea has been placed beyond iloubt ; but of 

 that the foliage has only yet been seen, in which respect it seems not to differ from E. alba. 

 Indeed also E. Decaisneana, if rightly recognized, may prove only a variety of E. alba. E. Leu- 

 cadendron (Ileinwardt in De Vriese plantse Reinwardtiauie p. 03) is according to Miquel 1. c. 1085 

 synonymous with E. alba. Dr. iSchcffer, informs me, that it has a white blurring bark, much 

 resembling that of Melaleuca Leucadendron, and that the Timor name therefore is Kajoc-poctih
