12. Hedwigia Sw.^ — Mowers polygamous, 4-6-merotis, or more 

 rarely (Trattinickia ^) 3-meroiis ; calyx short, imbricated. Gamo- 

 petalous corolla more or less Mgli tubular ; lobes valvate, finally 

 recurved at apex. Stamens twice as numerous as petals, 2-seriate 

 bypogynously or slightly perigynously inserted with perianth outside 

 annular crenate disk; filaments free; anthers introrse, 2-rimose. 

 Germen (in male fiower rudimentary) 2-5-locular; style capitate-2- 

 5-lobed, stigmatiferous at apex. Drupe ; pyrenas 2-5, with difficulty 

 or not solubile, 1-spermous; seeds descendent; cotyledons of 

 albuminous embryo plano-convex, rugose or contortuplicate. Other 

 characters of Bursera. — Balsamic trees ; leaves alternate or suboppo- 

 site, imparipinnate ; folioles opposite coriaceous; inflorescence 

 terminal or axillary of Bursera? {Tropical America^) 



III. ANACARDIE^. 



13. Schinus L. — Flowers polygamous or dicecious ; receptacle 

 rather convex or depressed. Sepals 5, imbricated. Petals 5, alter- 

 nate, longer, imbricated. Stamens 10, 2-seriate, verticillate, inserted 

 below outside between the lobes of orbicular rather wide disk; 

 filaments free ; the oppositipetalous shorter ; anthers introrse, 2- 

 rimose. Germen (rudimentary in male flower) sessile, 1-3-locular ; 

 1 cell fertile ; others effete or not conspicuous ; style-branches 3, 

 inserted at summit of germen, capitellate stigmatiferous at apex ; 

 ovule ascendent from summit of funicle and more or less high 

 inserted in ^lateral cell, pendulous anatropous ; micropyle introrse, 

 superior. Truit drupaceous, subglobose; epicarp usually rather 

 hard, glabrous ; mesocarp small ; putamen coriaceous or osseous, 

 longitudinally streaked, oily or resinous. Seed descendent com- 

 pressed ; albumen small or ; cotyledons of rather thick embryo, 

 flat; radicle rather long, ascendent. Eesinous, fragrant trees 

 or small trees ; leaves alternate, simple {Duvaua) or oftener impari- 

 pinnate ; folioles sessile opposite or alternate ; flowers in much
