II. HIBBEETIEiE. 



4. Hibbertia Andr. — Flowers 5-merous. Sepals imbricated 

 persistent. Petals 5, more rarely 2-4, alternate with the sepals, 

 variably imbricated deciduous. Stamens cc, liypogynous or more 

 rarely slightly perigynous, all fertile or some sterile ; in some {Cy- 

 dandrece) peripheral, in others {Pletcrajidrea) unilateral ; staminodes 

 external, peripheral or unilateral, or more rarely on each side 

 of the fertile stamens, intermixed with them, or internal ; anther- 

 cells 2, oblong introrse or lateral adnate to a linear connective, more 

 rarely rotundate, shorter than the connective which is dilated at 

 the apex ; dehiscence longitudinal. Carpels l-oo (usually 6-10), all 

 free, or more or less adnate at the base to the conical receptacle, 

 1-00 - ovulate ; ovules in 2 rows, ascending or subhorizontal. Fruits 

 dry, usually dehiscing as follicles, or in 2 valves. Seeds 1-8, arillate. 

 — Shrubs, more rarely undershrubs or herbs, sometimes trailing 

 or twining ; leaves petiolate or sessile ; flowers soHtary terminal, or 

 leaf-opposed, or often in unilateral false spikes or racemes {Oceania, 

 Madagascar). See p. 90. 



5. Schumacheria Vahl. — Flowers 5-merous. Sepals imbricated, 

 persistent. Petals usually 5, imbricated. Stamens oo , unilateral ; 

 filaments cohering at the base ; anthers erect, spuriously porricidal 

 dehiscing by two short apical clefts. Carpels 2, 3, excentric, 

 1 -ovulate, when ripe dry and indehiscent; seed arillate. — Climbing 

 shrubs ; branches flexuous ; leaves parallelly penniveined ; flowers in 

 one-sided subspicate racemes, with (usually 2) lateral bracts ; racemes 

 axillary or terminal, branching {Ceylon). See p. 97. 



6. Tetracera L. — Flowers hermaphrodite, more rarety poly- 

 gamous. Sepals 3-6 (usually 5) imbricated. Petals 1-6 (usually 5) 

 imbricated. Stamens go , peripheral ; filaments all free, or aggregated 

 into a few bundles for a variable height ; anthers sterile abortive, 

 or more usually 2-celled ; cells lateral extrorse or introrse, sub- 

 parallel or more or less diverging at the base ; filaments dilated 

 entire or 2-fid at the apex. Carpels 1-6, free ; ovaries 2-3o - ovulate ; 

 ovules ascending or subhorizontal. Fruit dry or more or less 

 fleshy, dehiscing as a follicle or in two valves, more rarely inde-
