Hedge Periploca. Shrub climbing. 



Cult. P. Graeca and P. angiutifdlia are handsome, hardy, 

 twining shrubs, well fitted for covering bowers or trellis work, or 

 for training against a wall ; these grow freely in common 

 garden soil, and are increased readily by layers or cuttings. 

 The P. laetigata will require protection in winter, either by 

 being planted in a greenhouse, or against a south wall, in which 

 latter situation it will require to be protected by mats in frosty 

 weather, in winter. 



LXXXIII. PHYLLANTHERA (from 0vXAov, phyllon, a 

 leaf ; and avSripa, anthera, an anther ; in reference to the anthers 

 being dilated and foliaceous at the apex.) Blum, bijdr. p. 1048.

 Corolla deeply 5-parted, fleshy, discoid inside at the base, with-

 corpuscles of the stigma. Ovarium didymous. Style one, 

 bisulcate at the base ; stigma capitate, mutic. A twining shrub ; 

 with opposite, lanceolate, glabrous, transversely-veined leaves ;
