482 cix. ACANTHACBJS. (C. B. Clarke.) [Acanthus. 



7. A. long'ibracteatus, Kurz in Flora 1870, 363, and in Journ. As. 

 Soc. 1870, ii. 79 ; leaves long-petioled ovate or elliptic-oblong acute at both 

 ends remotely toothed pubescent, spikes terminal finear-oblong, bracts lan- 

 ceolate spinous-mucronate, corolla f in. 



Pegtt; Brandis (fide Kurz). 



Annual, 3-5 in. ; stems terete, decumbent or ascendinff, densely pnberulous. 

 Leaves 2 in., membranous, setulose between the teeth, sparsely hairy above, nerves 

 beneatb pubescent. Spikes as in A. leucostacht/us ; racbis pilose; bracts ^ in., 

 pubescent, lower entire, upper with 2 or 3 spinous teeth on each side ; bracteoles as 

 long as the bracts, linear. Calyx J in., adpressedly pubescent and nervose ; lower 

 segment deeply 2-fid, lobes lanceolate acuminate. Corolla 5-lobed, minutely hirsute 

 in the throat. — Copied from Kurz. Notwithstanding the narrow bracts and small 

 corolla, I suspect that this is Kurz's subsequently described A. longipeliolatus.

 shortly bifid or subentire. Capsule ovoid or oblong, 2- or 4-seeded below

Barleria lupulina, Lindl. in Bot. Reg. t. 1483, is frequently cultivated in India, 

 and appears as an escape. 



Sarleria rubra. Ham., and B. spicata, Roxb., are entered in Steudel's Nomencla- 

 ture as Indian : but it is not known from what source obtained. 



Subgenus 1. Prionitis. Capsule ovoid, beak solid, 2-seeded close to 

 the base.
