cousider a good section of Eugenia^ altLough, in inflorescence, 

 passing into Eueugenia. 



Biplioneugenia^ Serg, has three species, with the calyx-tube 

 produced, as in Myrciaria, but "vvith the ovules and inflorescence 

 of Eueugenia. Gatinga, Aubl., has the inflorescence oiMyrciaria^ 

 with the calyx and ovules oi Eueugenia. 



Cleistocaltx, Blume, is unknown to me, except from the 

 description and figure of Blume, Mus. Bot. i. 84, t. f>Q, It is 

 represented in bud only, with detached fruits, which are entirely 

 those oi Eugenia^ to which genus Miquel refers the plant. The 

 figure in bud is that of Acicalyptus ; but Blume describes the 

 calyx-limb (closed before flowering, as in Acicalyptus) as split- 

 tmg into four or five irregular lobes before it falls, instead of 

 cohering in a circumsciss operculum ; this, however, may have 

 been accidental in a single detached calyx, or even conjectural ; 

 for, if well ascertained as an essential character, it would have 

 been represented in the figure. Should Acicalyptus really prove 

 to have a Eugenioid embryo, it might be united with Cleistocalyx 

 lu a genus closely allied to Eugenia^ but difibrlng from its section 

 Janibosa (as Calyptrantlies does from Myrcia) by the opereulate 

 calyx ; and such genus would probably, notwithstanding a slight 

 difierence in the placentation, include also Piliocalyx, recently 

 I>roposed by Brongniart and Gris, if the embryo, as yet un- 

 known, should prove to be that of Eugenia. 



Calycoeectes, Berg, including Schizocalyx, Berg, contains a 

 few American species diff'ering considerably froui each otlicr in 

 'isj^ect, but supposed to be all characterized by a Prfidium-Jike 

 calyx with a Eugenioid embryo, thus difl'ering from Eueugenia as 

 Cleistocalyx does from Jamhosa. The seed, however, appears to 

 have been examined oiJy in one species ; and none of our speci- 



niens have ripe fruit ; and it is with doubt that we have tempo- 

 rarily retained the genus. 



Aitlacocaepus, Berg, comprises two American species, with 

 the habit and inflorescence of the large-leaved Eueugenice or 

 *^atingas. Their flowers are unknown ; but the fruits differ from 

 the majority of Eugenia in the very hard thick pcricarj), separa- 

 ting when dry more or less readily into 1-seeded pyrenes. llo\w 

 tar that may take place in any true Eugenia we do not know. 

 Ahe fruit oi Eugenia was originally supposed to be a drupe, 



CupHEANTurs, Seem., which we had placed amongst genera of 

 doubtful affinity, has been further elucidated by the observa- 

 tioua of Brongniart and Gris and by the notes of Vieillard, our
