368 NATURAL HISTORY OF PLANTS, 



35. Angophora Cav.^ — Flowers nearly of Eucalyptus \ calyx 

 gamophyllous, 5-costate, membranous at margin, remotely 5-dentate ; 

 teeth rather prominent. Petals 5, distinct, connivent in a globe, 

 highly imbricate, deciduous at base. Stamens gyneecium and capsule 

 of Eucahjptus ; seeds ^ in cells 1, ovate piano -compressed, peltately 

 affixed ; cotyledons of straight exalbuminous embryo orbicular-cor- 

 date, plane or at margin alternately replicate; radicle very short 

 straight. — Trees or shrubs; leaves, generally opposite, coriaceous, and 

 other characters of Eucalyptus ; ^ flowers in terminal compound- 

 ramose corymbiform cymes. (East Australia^) 



36. Backhonsia Hook. & Haev.^ — Flowers oftener 4-merous ; 

 receptacle deeply cupular or obconical, adnate at base to germen 

 within. Sepals 4, often subpetaloid, persistent. Stamens oo ; fila- 

 ments free, slender, go -seriate ; anthers versatile. Germen free to a 

 variable extent, 2-locular ; style slender simple, scarcely dilated at 

 stigmatose apex ; ovules go , inserted on longitudinal or subapical 

 placenta, transverse or descending, nearly straight or recurved. 

 Fruit capsular, more or less free, girt with persistent perianth, 2- 

 coccous, indehiscent (?) ; seeds cuneate or obovate; cotyledons of 

 straight embryo straight or (where known) conduplicate ; radicle 

 shorter. Small trees or shrubs ; leaves opposite ; flowers^ in axillary 

 compound umbelliform or capituliform cymes ; bracts very caducous. 

 (East, Australia^) 



37. Osbornia F.Muell.® — Flowers generally 8-merous, apetalous ; 

 receptacle concave turbinate, not produced beyond germen adnate 

 within. Sepals 8, sub-2- seriate,' persistent. Stamens go , few- seriate ;
