1. EUGENIA, Linn. ; M. Brit. lud. ii. 470. 



Trees or shrubs, nearly always evergreen ; leaves gland-dottedj with rare 

 exceptions opposite. Fl. usually tetramerous ; inflorescence terminal or lateral, 

 usually cymose but in some species centripetal, racemose. Calyx-tube fre- 

 quently with resin cavities below the surface, articulate with pedicel, two 

 bracteoles frequently at its base, enclosing the two-celled ovary and in most 

 species produced beyond it as a more or less campanula te cup. Calyx segments 

 persistent or deciduous. Petals gland-dotted, either free, expanding, or united 

 into a cap (calyptra). Stamens numerous in several series, inserted on a more 

 or less conspicuous disk at the mouth of calyx-tube, anthers small versatile. 

 Ovules several or man}^ in each cell, placenta in the middle of the dissepiment. 

 Er. a berry, 1- or few-seeded, embryo thick and fleshy with a very short 

 radicle, the cotyledons fleshy, either separate or united in a homogeneous mass. 

 Species 650 tropical and subtropical, in Asia and tropical America, a few in 

 tropical Africa and Australia. 



The species here enumerated are frequently classed under 3 genera : Jamho^a, Eugenia 

 and Syzijijiuni, Engler u. Prantl. iii. 7. 78.

 elliptic-oblong, obtuse, narrowed to the rounded or slightly cordate base, blade 

 4^12 in., petiole stout, generally very short. Fl. white or purplish-pink, in

 escence, calyx-tube clavate, free portion a very shallow cnp, l-lj in. long, ribbed when 

 dry, pedicels short, stout. Fr. globose, the size of an orange, crowned by the spreading
