genia Miclielii^ Lam,, and forms part of the genus Stenocali/x 

 proposed by Berg on account of a peculiarity in the .inflo- 

 rescence. The peduncles, l-flowered, as in Hueugenia^ appear 

 towards the base of axillary branches, and the lower subtending 

 leaves are reduced to small bracts, the branch becoming leafy 

 without flowers at the end ; the inflorescence is thus an axillary 

 raceme growing out into a leafy branch — a very vague character 

 depending on the degree of development of the lower floral 

 leaves. Berg adds to it that the calyx-lobes are longer and nar- 

 rower than, in Eugenia ; but that only applies to a portion of the 

 species. In S, laxus^ Berg, and some others, they are broadly 



ovate. PhyllocaJyx, Berg, is only distinguished from Stenocaly^ 

 by the still greater foliaceous expansion of the calyx-lobes. 

 Ilexaclilamys^ Berg, is a single species with hexamerous flowers ; 

 but we have seen that in many large genera of Myrtacese there 

 are species with an exceptional increase or reduction in the 

 number of parts, constant or occasional, without the circum- 

 stance being available for a generic character. 



Jossinia, Comm., was established by DeCandolle for a few 

 Mascarene species, which he com|)ared to Myrtus^ believing, from 

 the numerous ovules, that they had probably the seeds of that 

 genus but with the 4-merous flowers of Eugenia^ stating also 

 that they differ from the latter genus in the broader staminal 

 disk. Blume, however, has since shown that they have entirely 

 the fruit and seeds of Eugenia^ in which genus also there are 

 several instances of a staminal disk at least as broad as in Jossiniaj 

 which must now be reduced to the section Eueiigenia, ^ 



Myrciaria^ Berg, contains a considerable number of American 

 species, distinguished from Eueugenia by the calyx-tube pro- 

 duced above the ovary, as in Aulamyrciaj Jambosa, &c., and by 

 the ovules, two in each cell (as in Myrcia), not several (as in all 

 other EugenicB). Had these characters been accompanied by any 

 general difference in habit or inflorescence, they might have well 

 served to maintain the genus ; but some of the five series under 

 which the species are classed, are more generally different from 

 each other than from corresponding groups of Eugenia, The 

 first series, Eichotomce^ have the inflorescence of Myrcia^ and 

 will probably prove to belong to that genus, the fruit of the 

 three species referred to it being at present unknown. The Pant- 

 culatm require furtlier elucidation, the fruits of several of them 

 also not having been described. The Glomeratw and LateriJlor<e 

 constitute a more natural group, which we may, with Grisebacn,
