Stems and leaves of A. ilicifolius ; base of petiole spinous or not. 'Bracts in., 

 usually caducous before the flowers expand. Capsule f in. Seems to differ from A. 

 ilicifolius by the much smaller calyx, corolla and capsule. Vahl puts the difference too 

 strongly when he says the flowers are only one quarter the size. Bentham (Fl. 

 Austral, iv. 548) doubts the distinctness of the species. Herbarium examples of A. 

 ilicifolius with the flowers in bud, which show neither the evanescence of the bracts 

 uor the true size of the corolla, can only be distinguished by the presence of the 

 bracteoles.

Stems twining in long grass, iuternodes often 4-8 in. Leaves 3| by 1_ in., 

 obtuse or subacute, base attenuated; petiole $ in. Spikes 2-3 in., hardly inter- 

 rupted; flowers sub-2-seriate; bracts | in., elliptic; acute. Calyx - in., outer 

 segments elliptic, acute, glabrous ; inner similar, much shorter. Corolla 1 in., white, 

 slightly tinged yellow (Wallich), probably when fading; rose (Nees). The syn. of 

 Kumphius (Herb. Amb. vi. t. 71, tig. 2, wrongly cited as t. 72 by Nees) has alternate 

 leaves and fruits quite unlike Acanthacece.
