Stamina co, co-seriata, libera, v. basi in phalanges 4 prsesertim in alabastro obseure con- 
nata, filamentis filiformibus; antherz versatiles, seepius parvze, loculis longitudinaliter de- 
hiscentibus sspissime parallelis rarius divarieatis. Ovarium 2- rarissime 3-loculare ; 
stylus filiformis, stigmate parvo; ovula in loculis oo, placentz e septo parum prominenti 
affixa, ssepius ineurvo-adscendentia, in seet. Myrciaría 2-4. Bacca subdrupacea v. pul- 
posa, rarius subsieca et fibroso-cortica, calycis limbo persistente coronata v. rarius limbo 
deciduo truncato. Semina pauca, sepius 1-4, globosa v. mutua pressione varie compressa, 
testa membranacea v. cartilaginea ; embryo crasso-carnosus, radicula brevi, cotyledonibus 
crassis plus minus conferruminatis v. distinctis hemisphsricis v. heteromorphis.—A rbores 
fruticesve, glabrz v. rarius tomentoss v. villosee. —F'olia opposita (in una specie alterna ?), 
coriacea v. membranacea, pennivenia. Inflorescentia nune centripeta, pedicellis 1-floris 
oppositis ad axillas solitariis fasciculatis v. in racemum brevem (ramum aphyllum) dis- 
positis, nune centrifuga cymis terminalibus densis v. in paniculas terminales lateralesve 
tricehotomas dispositis. Bractes et bracteole sspius parvse caducissimrwque, rarius folia- 
ce: persistentes. 
Species descriptze ultra 700, quarum ad 500 bons videntur, in America tropica v. subfropica et 
in Asia tropiea eopiosissime erescentes, in Australia et Africa pauciores. 
Genus vastissimum, quoad limites valde incertum et species extricatu difficillimz. — A Myrto em- 
bryone solo distinguitur, et species plurimze imprimis Chilenses v. Andinz, olim ob flores 4-meros 
sub Eugenia deseriptz, nune seminibus examinatis ad Myriwm transferuntur. Genera Americana, 
a Bergio imprimis ob ealycem separata, a Grisebaebio iterum eum Zugenia junguntur. Genera 
Asiatiea a Grisebachio ob inflorescentiam servata, a Wightio et Grayio pro sectionibus Eugenie 
habentur. Hane sententiam sequimur, et genus in integrum servandum videtur, inque sectiones 
sequentes dividendum v. si mavis in subgenera 2: 1. Jaj;ubosa inflorescentia centrifuga ; 2. Euge- 
niastrum, Griseb., inflorescentia centripeta. 
1. Jambosa. Inflorescentia cymosa, densa v. trichotome divarieata, sepius terminalis. Flores 
4-meri, szepe majusculi, Calyx turbinatus, nune angustus, nune latissimus, tubo supra ovarium plus 
minus produeto, limbo partito siepius persistente. Petala patentia, singillatim decidua.— Species fere 
60 (ab auctoribus ultra 90 enumeratze), omnes gerontoges, pauere etiam in America tropica culte.

SrRoxcyrocaLxx, Blume, Mus. Bot. i. 89. t. 54 (Eugenie $ 4, Mig. Fl. Ind. Bat. i. pars 1. 
442), a Jambosa non differt nisi calyeis tubo fere hemisphzerico post anthesin globoso, parte libera 
per anthesin latissima. 
GxrPxza, Blume, l. c. 88. t. 35 (Eugenie $ 2, Mig. Fl. Ind. Bat. i. pars 1. 410), species a. nobis 
non visa, differre dieitur calycis lobis valvatis et periearpio fibroso-cortieato. Calyx tamen in aliis 
generibus e. g. Leptospermo ab auetore valvatus dieitur, dum in speciminibus ipsis suis in alabastro 
juniore lobi distinete imbricati sint. ' Pericarpium in pluribus Ja;ibosis fere siccum et fibrosum 
est. 
CrzisTOCALYX, Blume, l. c. 84. f. 56 (Eugenise $ 3, Miq. Fl. Ind. Bat. i. pars 1. 441), a Jambosa 
vix differt calycis limbo in alabastris valde juvenilibus ccncreto clauso demum in lacinias 4—ó fisso.
