This may not be indigenous in the Malay Peninsula. A note of Curtis says 

 " originally collected in Burma by Boxall."

Singapoee: Lohh. Penang: Wallich 234^3. Peeak : alt. 2000 ft., 

 Curtis 1313 ; alt. 300 to 800 ft.. King's Collector 7271, 8490. 



10. Steobilanthes pachyphyllus, C. B. Clarke, n. sp. Shrub, up 

 to 4 ft. high. Leaves opposite, equal, 5-5 by 2 in., elliptic, obscurely 

 obovate, acute at either end ; under surface pubescent (" silvery grey " 

 when fresh), densely clothed with rhaphides, obscurely crenate, remark- 

 ably thick, hard in texture ; petiole 1-5 in. Panicle terminal, long-

 subequal, '25 in. long, linear, glabrous, full of rhaphides. Corolla 1-25 in. 

 long, very narrowly tubular-canipanulate, light-blue. Stamens 4 ; fila- 

 ments hairy in the lower half ; anthers oblong, muticous ; pollen 

 exactly globose, 40 jx in diam., 20-ribbed, 2-stoppled. Style thinly hairy. 



Peeak: hill-top, Scortechini 1786; alt. 1600 to 2000 ft.. King's 

 Collector 7150. 



The material represents the species imperfectly ; it appears allied to S. collinus, 

 Nees ; the texture of the leaves is distinctive, and the globose pollen is very unusual 

 in the genus Strobilanthes. 



13. Acanthopale, C. B. Clarke, n. gen. 

 Pollen globose, echinate, without ribs ; otherwise as Strobilanthes. 

 Species 8, in tropical Africa with Madagascar ; and many Indian. 



Among the Strobilanthes to be removed to Acanthopale are S. lanceolatus, Nees; 

 S. pvlneyensis, C. B. Clarke ; S, Zenkerianus, T. Anders. ; S. drnottiamis, Nees ;
