Timor ; but that is mere guesswork, aud Eoxburgli's short descrip- 

 tion is quite at variance Avith that species. Blume, iu his ' Museum 

 Botanicum/ i. p. 83, adds three species :—K deglupta, described 

 from a Celebes specimen in leaf only, which he found in Eein- 

 wardt's collection under the doubtful name of Populits ? degJuhata ; 

 E, versicolor, from the Moluccas, taken up from Eumphius's de- 

 scription and rude figure o? Arhor versicolor Ay-alla (Herb. Amb. 

 111. p. 122, t. 80, not t. 53^ which is an Eugenia) without flowers 

 or fruit ; and E, sarassa, Blume, founded on liumphius's incidental 

 mention of the Sarassa-tvee in the same article, all three species 

 conjecturally referred by Blume to Eucalyptus on account of their 

 resinous bark, described as detaching itself in patches. A fifth 

 species from a still more distant region, Mindanao, one of the 

 Philippine islands, is described by A. Gray in the ' Botany of the 

 American Exploring Expedition,' p. 554, under the name of ^. 

 multiflora, Eich., from a specimen iu leaf, and with a panicle of 

 old fruits from which the calyx-limb and opercuhim, if any, are 

 fallen away, and the open capsules have lost all their seeds. The 

 4-celled (not 3-celled) capsule is the only character leading us to 

 suppose that it may be a Eucalyptus rather than a Tristania or 

 a Metrosideros, No mention of it occurs in Blanco's 'Flora.' 



The Methosidere^, forming the last subtribe of Leptospermeae, 

 scarcely differ from Euleptosperme?e in their floral or carpo- 

 logical characters, but form a not uunatui^al group, chiefly dis- 

 tinguished by their inflorescence and foliage, which connect them 

 with Myrteae, almost passing, indeed, into that tribe through 

 £acJchousia diixdi Oshornia. One or two species of Metrosideros and 

 perhaps of Tristania have something of the aspect oi Eucalyptus^ 

 but not the inflorescence ; nor do any of the subtribe ever show tlie 

 closely sessile flowers of Euleptospermese. If, again, some of the 

 smaller-leaved Metrosiderese may occasionally approach in habit 

 a few of the larger-leaved Ba^ckeese, the stamens, and especially 

 the embryOj will always supply good distinctive characters. The 

 Metrosidereae contain also a larger proportion of extra-Australian 

 species than any other subtribe of capsular Myrtacese. 



The proper division of the tribe into genera and subgenera is 

 not easy to determine upon — not so much from the want of tangible 

 characters, as in Myrte^e, but from tlie number of monotypic or 

 almost monotypic forms, which leave it doubtful and in some 

 measure an arbitrary matter whether they should be considered 

 specific, sectional, or generic. We have, in our ' Genera Plantar um,* 

 admitted eleven genera; but the number might, with almost equal
