another from the base upwards, and spreading on anthesis. The 

 live stamens have their filaments longer than the introrse two-celled 

 anthers, which dehisce longitudinally. The two 

 multiovulate placentas, at first parietal and free, Biliardiera variifoiia. 

 come into contact, and often adhere along' the 

 middle line of the ovary. The genus comprises 

 two or three undershrubs, 2 flexuous or twining, 

 with pretty, drooping blue flowers. C/ieirant/iera 3 

 has nearly the same flowers ; but the anthers all 

 fall to one side of the androceum instead of sur- 

 rounding it regularly ; and their cells open by 

 an apical pore. 4 The fruit is dry and loculicidal, 

 with bifid valves. The species 5 of this genus ap- 

 proach Sollya in habit and inflorescence. Billardiera? whose flower 

 is also formed on the same plan as in Soil// a, has its petals 

 adherent or connivent halfway up into a tube (fig. 430) ; while 

 the anthers, of longitudinal dehiscence, are shorter than the
