12. Hedwigia Sw. ^ — Flowers polygamous, 4-6-ineroiis, or more 

 rarely {Trattinickia ^) 3-merous ; calyx short, imbricated. Gamo- 

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

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

 hypogynously or slightly perigynonsly inserted with perianth outside 

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

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

 5-lobed, stigmatiferousatapex. Drupe; pyrenas 2-5, with difficulty 

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

 albixminous embryo plano-convex, rugose or contortuplicate. Other 

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

 sito, imparipinnate ; folioles opposite coriaceous ; inflorescence 

 terminal or axillary of Biirsera? {Tropical America,'^)

13. Schinus L. — Flowers polygamous or dioecious ; 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. Fruit 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 {Diwmiu) or oftener impari-
