410 NATURAL HISTORY OF PLANTS. 



8. Buckinghamia F. Muell. 1 — " Flowers nearly of Grevillea ; 

 perianth much recurved on one side, finally falling down. Anthers 

 subsessile muticous ; cells diverging. Hypogynous gland nearly 

 semi-annular. Germ en pluriovulate ; style filiform deciduous ; apex 

 laterally orbiculate stigmatiferous. Follicle subsessile, obliquely 

 orbiculate-ovate, compressed, shortly beaked, 3-6-seeded ; seeds as- 

 cending, surrounded by a narrow wing. — A tree ; leaves alternate 

 ovate-lanceolate entire ; flowers 2 in elongated racemes ; pedicels 

 paired, minutely 1-bracteolate 3 {Australia'). 



9. Grevillea E. Br. — Flowers hermaphrodite ; perianth 4-fid or 

 4-leaved, deciduous, sometimes regular or subregular {Anadenia), 

 with apex globose {Manglesia), more frequently reflexed or recurved, 

 sometimes irregular {Eugrevillea) ; leaves valvate, antheriferous, and 

 long cohering at dilated concave apex. Anthers sessile or subsessile, 

 ovate or oblong, introrse, muticous or subapiculate. Disk hypo- 

 gynous, usually cleft behind, more rarely subannular, minute, or 0. 

 Gerrnen stipitate, with stalk sometimes adnate to perianth, more 

 rarely sessile, often ventricose behind ; ovules 2, collaterally ascend- 

 ing and anatropous. or hemitropous ; micropyle inferior extrorse ; 

 style sublateral, bowed or straight, more rarely shortened, at apex 

 discoid, flat, concave, convex, or conical, usually laterally or obliquely 

 grooved, stigmatiferous. Follicle woody or coriaceous, ovate or 

 subglobose, mucronate, or beaked by persistent style, smooth, warty, 

 or echinate, 1-2-valved. Seeds 1 (the other abortive) or more fre- 

 quently 2, ovate or subrotund, unsymmetrical, compressed alter- 

 nately, wingless, or with a membranous or somewhat fleshy mem- 

 branous 1 -lateral wing, more rarely broadly winged all round 

 {Cgcloptera), embiyo fleshy exalbuminous ; radicle inferior. — Shrubs, 

 or more rarely undershrubs or trees ; leaves alternate, flat, or terete, 

 entire, or variably divided ; flowers in simple or branched axillary or 

 terminal racemes, more rarely solitary or paired ; pedicels usually in 

 pairs in axil of each bract, rarely solitary or more numerous {Oceania, 

 especially Australasia). See p. 386.
