ACANTHACEJ5 (S. Moore) 89 



magenta. Corolla 23 mm. long ; tube barely 10 mm. long, 1 mm. or 

 slightly more wide in its lower part, and only 2 mm. at the throat ; 

 lower lip 13 mm. long, 6 ■ 5 mm. at the widest part, its lobes deltoid- 

 rotundate, and 1'25 mm. long, the mid-lobe 2 "25 mm. broad. 

 Filaments stout, 10 mm. in length. Anther-cells 2 mm. long. Ovary 

 1 • 5 mm. Style 17 mm. long. 



Quite unlike any African species known to me. In habit it 

 resembles H. jphyllostachys Bak. from Madagascar, but to mention 

 one point only, the involucres of the two are different.
