1 b^ \ in. oblong, two f by ^g in. Corolla and stamens as in A. ilioifolius, the

 species of Acanthus, and without the excurrent point of Slepharis. Capsule not 

 seen.

Stems and leaves of A. ilicif alius; base of petiole spinous or not. Bracts i in., 

 usually caducous before the flowers expand. Capsule | in. — Seems to difler 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 

 nor the true size of the corolla, can only be distinguished by the presence of the 

 bracteoles. 



6. A. volubilis, Wall. PI. As. Bar. ii. 56, t. 172 ; twining, unarmed, 

 leaves oblong or elliptic entire glabrous, spikes linear-oblong, braoteoles 0,

Stems twining in long grass, internodes often 4^8 in. Leaves 3i by 1| in., 

 obtuse or subacute, base attenuated; petiole \ in. Spihes 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 

 Eumphius {Serb. Ami. vi. t. 71, flg. 2, wrongly cited as t. 72 by Nees) has alternate 

 leaves and fruits quite unlike Acam,thace<e.
