ACANTHACEJE (S. Moore) 15 
wrinkled upon the upper side; lateral ribs on each side 3, the basal, 
coursing close to the margin, sometimes obscure, prominent on the 
lower side, openly arching, the reticulum well seen especially on the 
underside. Pedicels + 1:5 em. long.  Bracteoles 15 mm. long, 
puberulous within. Calyx 1 mm. long, or rather more. Tube of 
corolla 16 mm. long, 8 mm. wide below and 8 mm. at the throat; 
lobes about 8 x 8 mm. Smaller anthers 5 mm. long, larger 7 mm. 
Disc 2 x 3 mm. Style about 1:5 mm. long. 
Allied to A. phytocrenoides Gilg, but with quite different bracteoles 
among other features; these latter organs are more like those of 
A. madagascariensis S. Moore.
