434 cix. ACANTHACK51. (C. B. Clarke.) [Strobilanthes. 



Stems 1-2 ft., much branched, rigid. Leaves 2 by IJ in., shortly acnminate at 

 both ends, conspicuously lineolate above; nerves 5-6 pair; petiole j in. Heads 

 numerous, terminal, J in. diam., each closely embraced by the two uppermost leaves (ex- 

 clusive of the proper bracts) ; bracts } in., linear-oblong, at first nearly glabrous or 

 hairy ; bracteoles f in., linear, at first nearly glabrous or hairy. Calyx J in., divided 

 hardly half-way down, obscurely or prominently hairy at flower-time, hirsute in fruit, 

 segments narrowly lanceolate. Corolla 1^ in., blue or whiteish, glabrous without, 

 hairy along 2 lines within ; linear base of the tube about as long as the suddenly- 

 widened ventricosa part. FilamenU hairy nearly to the summit ; rudiments often 3, 

 whereof 2 often carry minute rudimentary anthers. Ovary slightly hairy upwards. 

 Capsule I in., 4-seeded. Seeds | in. long, very thin, glabrous ; areoles 0. — There is no 

 difference between the typicaiybttonu and the Tar. capitatus ; the heads on one stem 

 which appear (superficially) g^brous in flower are very hairy in fruit, owing to the 

 development of the hairs on the bract, bracteoles and calyx. 



** Seeds (in water) densely hairy except on two lateral circular areoles 

 near the base on each face. — (Linear or subcylindric base o£ the corolla short, 

 more gradually narrowing into the ventiicose portion than in the preceding 

 section. — Species of the S. Deccan Peninsula.)
