LI. MYRTACEiE. 
655 
29. EUGENIA, Linn. 
(After Prince Eugene of Saxony.) 
(Jossinia, Comm.; Jambosa, DC.; Syzygium, Gcertn.; Acmena, DC.) 
Calyx-tube from globular to narrow-turbinate, not at all or more or less pro- 
duced above the ovary ; lobes 4, very rarely 5, from large and imbricate to very 
short and scarcely prominent above the truncate margin. Petals 4, very rarely 
5, either free and spreading, or more or less connivent, or connate and falling off 
in a single calyptra. Stamens numerous, in several series, free or obscurely 
collected in 4 bundleg ; anthers versatile, usually small, the cells parallel or very 
rarely divaricate, opening longitudinally. Ovary 2-celled or very rarely (in species 
not Australian) 3-celled, with several ovules in each cell, or only 2 in an American 
section. Fruit a berry or sometimes almost a drupe, or nearly dry with a fibrous 
rind. Seeds either solitary and globose, or few and variously-shaped by compres- 
sion ; testa membranous or cartilaginous ; embryo thick and fleshy, with a very 
short radicle, the cotyledons either united in an apparently homogeneous mass or 
more or less separable. — -Trees or shrubs. Leaves opposite, penniveined. Flowers 
(in the Australian species) either solitary in the axils or in lateral or terminal 
trichotomous cymes or panicles. 
A most numerous genus, spread over the tropical and subtropical regions both of the New and 
the Old World. The genus has been variously subdivided into sections or genera by different 
botanists according to whether they have worked chiefly upon American or upon Asiatic species. 
The most convenient course, however, appears to be that proposed by Wight, A. Gray, and 
others, to retain under the genus all Myrtece with fleshy fruits and thick fleshy cotyledons with a 
very short radicle, except, perhaps, a very few American species with very different floral 
characters. — Bentli. 
Sect. I. Eueug eniae. — Pedicels short, 1-flowered, solitary or 2 toyether in the axils or at the 
old nodes. Calyx-tube more or less produced above the ovary, the border entire or very shortly 
sinuate-lobed, or with more prominent but very deciduous lobes. Petals more or less coheriuy in a 
calyptra, or rarely spreading and separately deciduous. 
(This section, more definitely characterised by the inflorescence than by the calyx, comprises 
only a few of the Old World species but very numerous American ones, and, according to the 
views of those who have studied chiefly American Myrtacea, should, with other species having 
a racemose or clustered (not trichotomous or cymose) axillary inflorescence, constitute the whole 
genus Eugenia, to the exclusion of Syzygium and Jambosa. — Benth. 
Leaves 1 to l^in. long, ovate orbicular or almost rhomboid 1 . E. carissoides. 
Leaves 2in. long, broadly ovate. Flowers 2 in each axil. Fruit globose, 
torulose 2 ,*E. unijlora. 
Sect. II. Syzyg’ium. — Flowers in trichotomous panicles or cymes. Calyx-tube more or less 
produced above the ovary, the border entire or very shortly sinuately-lobed, or with more prominent 
but very deciduous lobes. Petals more or less cohering in a calyptra and falling off together, or 
rarely spreading and separately deciduous. 
(These species are all natives of the Old World, although a very few have in some measure 
become naturalised in some parts of tropical America. The section is often considered as a 
genus, but there are too many species in which the character derived from the calyx and petals 
is doubtful or variable to allow of its being distinctly separable from Jambosa. — Benth.) 
Flowers in loose panicles, terminal or in the upper axils. 
Panicles corymbose. Petals cohering. Anther-cells divaricate. 
Fruit white or purplish, crowned by the circular sear of the calyx-rim 3. E. Smithii. 
Fruit crimson, globular, ljin. diameter, crowned by the circular scar 
of the calyx-rim and minute calyx-teeth 4, E. hemilampra. 
Fruit white, round or transversely oval, 1 to 2in. diameter ; circular 
scar of the calyx-rim 4 to 8 lines diameter. Seeds lor 2. ... 5. E.kuranda. 
Fruit hard, dark, globose, 2 or more inches diameter, crowned by the 
wide circular scar of the calyx-rim. Seed solitary 6 . E. gustavioides. 
Fruit depressed-globular, £ to lin. diameter, the scar of the calyx- 
rim sometimes not prominent 7. E. Ventenatii. 
Panicles reduced to a short dense corymb or head. Buds long, slender, 
and clavate. Stamens very short. Leaves narrow 8 . E. leptantha. 
Panicles trichotomous, divaricate. Buds nearly globular. Fruit juicy, 
red, roundish or oblong 9. E. Jambolana. 
Peduncles axillary and terminal. Flowers clavate in the bud, 0 to 8 
lines long. Stamens £in. long 10. E, carynantha.
