inCaryophyllus the long calyx-tvibe and coherent petals are parti- 

 cularly striking in the buds so well known as the cloves of com- 

 merce. And it is perhaps the great difference in the commercial 

 use of the plant that has induced subsequent botanists to endea- 

 vour to keep up the genus, even since it has been ascertained how 

 much the form of the calyx-tube varies from species to specie 

 Thus DeCandolle and others have attempted to add a character 

 derived from the stamens in the bud bein^jf arran^Tjed in four bun- 

 dies, separated by the indented teeth of the calyx ; but this is no 

 more than the impression of the thickened midribs of the sepals, 

 such as may be seen in the buds of other Hiigenm with exceed- 

 ingly numerous stamens, and disappears as the stamens expand. 

 We therefore cannot but agree with Wight in annexing Canjo- 

 pJiyllus to the section St/zi/(jium, as we would restore to the 

 section Jamhosa the genera Strongylocahjx^ Blume, Clavimyrtus^ 

 Blume, £ind Ilacromyrtus J Miq., all fovmded on the form of the 

 calyx-tube, globular in the first, long and club-shaped in the 

 second, still longer in the third. 



Jamhosa^ DC, and Microjamhosa^ Blume, were separated, the 



former from Eicgenia as then understood, the latter from Syzygiit'i^h 



and Jamhosa is still kept up by Miquel, on account of the caiyx- 



tube being in all three more or less produced between the ovary 



and the stamens; but this character has not appeared to us more 



definite or more conformable to habit in this case than in that 



of Aiilomyrcia. In many species of the section Jamhosa the 



ovary occupies, it is true, but a very small space in the bottom ot 



the deep calyx-tube ; but in others it reaches halfway up, or is so 



thickly fleshy at the top that it is difficult to say where it ends, 



and whether it does or not extend to the insertion of the stamen 



The difficulty of appreciating this character may be readily seen 



by a glance at Blume's figures of Stronyylocalyx and Gelpkea 



(Mus. Bot. t. 5i & 55), both referred by Miquel to the same 



genus, which ought to have the calyx-lobes divided to the 



ovary. - 



Acmena^ DC, was founded upon what was supposed to be the 

 3Ictrosideros florihunda, Sm., with a Syzygium calyx and fruit, 

 but with 5 very small free petals ; but, owing to the Impertect 

 materials he possessed, and the deficiency of authentic specimens, 

 DeCandolle had confounded three very different plants : — 1- -*-"*^ 

 true Metrosiderosjloribunda of Smith, with really 5-merous flowers 

 which has a capsular fruit, and is the Angophora intermedia, 



DC 2. The plant figured by Yentenat as Smith's M.Jloribunda
