368 NATURAL HISTORY OF PLANTS. 



35. Angophora Cav. 1 — Flowers nearly of Eucalyptus ; calyx 

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

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

 highly imbricate, deciduous at base. Stamens gynsecium and capsule 

 of Eucalyptus ; seeds 2 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 ; 3 flowers in terminal compound- 

 ramose corymbiform cymes. (East. Australia.*) 



36. Backhousia Hook. & Harv. 6 — Flowers oftener 4-merous ; 

 receptacle deeply cupular or obconical, adnate at base to germen 

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

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

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

 stigmatose apex ; ovules co , 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, indéhiscent (?) ; seeds cuneate or obovate ; cotyledons of 

 straight embryo straight or (where known) conduplicate ; radicle 

 shorter. Small trees or shrubs ; leaves opposite ; flowers 6 in axillary 

 compound umbelliform or capituliform cymes ; bracts very caducous. 

 (East. Australia. 1 ) 



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

 receptacle concave turbinate, not produced beyond germen adnate 

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