482 CIX. ACANTHACEEX. (C. B. Clarke.) [ Acanthus. 
7. A. longibracteatus, 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 linear-oblong, bracts lan- 
ceolate spinons-mucronate, corolla $ in. 
Pecu; Brandis (fide Kurz). 
Annual, 3-5 in.; stems terete, decumbent or ascending, densely puberulous. 
Leaves 2 in., membranous, setulose between the teeth, sparsely hairy above, nerves 
beneath pubescent. Spikes as in A. leucostachyus ; rachis pilose; bracts 4 in.» 
pubescent, lower entire, upper with 2 or 3 spinous teeth on each side; bracteoles as 
long as the bracts, linear. Calyx } 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. longipetiolatus. 
XXII. BARLERIA, Linn. 
Undershrubs or herbs, spinescent or unarmed. Leaves opposite, entire. 
Flowers showy, purple blue yellow or white, sessile, solitary or in dense or 
sublax spikes ; bracts and bracteoles large, small or 0. Sepals 4, in oppo- 
site pairs, outer pair very much the larger, anterior often emarginate bi 
or deeply 2-lobed. Corolla-tube elongate, sometimes very long, funnel- 
shaped upwards; lobes 5, subequal, ovate, or elliptic, imbricate 1n bud. 
Stamens 2 with oblong 2-celled anthers; 2 small, rudimentary, or rarely 
with a few grains of pollen; rudimentary 5th often present. Dise large, 
often a toothed cup half enclosing the ovary. Ovary 4-ovulate ; style long, 
shortly bifid or subentire. Capsule ovoid or oblong, 2- or 4-seeded below 
the middle. Seeds compressed, ovate, hairs wavy silky close-adpressed non- 
elastic (except iu B. Gidsoni).—Species 60, tropical, mostly Old World. 
Barleria lupulina, Lindl. in Bot. Reg. t. 1483, is frequently cultivated in India, 
and appears as an escape. 
Barleria 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 l. Prionitis. Capsule ovoid, beak solid, 2-seeded close to 
the base. 
1. B. Prionitis, Linn.; Nees in Wall. Pl. As. Rar. iii. 93, and wi 
DC. Prodr. xi. 237 ; leaves elliptic acuminate at both ends spine-tippe 
glabrous or sometimes tawny sericeous beneath, flowers in terminal spikes 
yellow, bracts large elliptic spine-tipped, bracteoles very small bristles or 0;
