with a transverse row of small scale-like glands above the base within ; 

 lobes oblong, obtuse, reflexed, as long as the tube. Corolla-tube 3 lin. 

 long, wide above the middle, narrowed towards the base, which is attain 

 slightly widened, delicately velvety below the stamens within, not 

 twisted; lobes obovate-oblong, slightly oblique, acute, 4J-5 lin. long. 

 Stamens inserted above the middle of the corolla-tube ; anthers 

 scarcely IJ lin. long, tips scarcely exserted, tails rather short. Disc

to. V. psilocalyx, Pierre MS. A glabrous shrub, 6-9 ft. high ; 

 branches slender, grey. Leaves lanceolate, acuminate, long attenuate 

 at the base, 4-8 in. long, 1 J-2J in. broad, papery ; secondary nerves 

 very oblique, gently curved, 6-7 on each side ; petiole slender, J~l in. 

 long. Inflorescences terminal from the youngest branch-forks, few- 

 flowered, umbelliform, multibracteate ; peduncle slender, IJ in. long ; 

 bracts persistent, crowded at the base of the pseudo-umbel, oblong, 

 acute, 4-6 lin. long; pedicels slender, up to ^ in. long. Calyx sub- 

 campanulate, 7-8 lin. long, with a transverse zone of scg-nty small 

 glands somewhat above the base ; lobes oblong, obtuse or shortly 

 acuminate, about as long as the tube. Corolla yellow; tube sub- 

 cylindric, abruptly constricted at the middle and gradually narrowed 

 towards the mouth, 7-8 lin. long, twisted, pubescent on the filamental 

 ridges, otherwise glabrous within ; limb rotate ; lobes obovate- elliptic, 

 6-7 lin. long, crisp, brown when dry. Stamens inserted above the 

 middle; anthers 3 lin. long, tips scarcely exserted, tails long. Disc 

 annular, shorter than the carpels. Berries obliquely obovoid, with a 

 short recurved beak, up to \\ in. long ; pericarp rather thin when dry, 

 leathery, with slightly raised curved longitudinal ridges. Seeds about

 secondary nerves 6-7 on each side, very oblique, gently curved ; petiole 

 slender, up to 6 lin. long. Inflorescences solitary (always ?) from the 

 young branch-forks, nodding, of 1 or 2 contracted pseudo-umbels, multi- 

 bracteate ; peduncles very slender, up to 6 in. long ; bracts broad-ovate 

 or oblong, obtuse or subobtuse, 3-4 lin. long, crowded at the base of the 

 pseudo-umbels, subpersistent, if the pseudo-umbels are paired, with 2 

 longer oblong bracts at the base of the dichotomy ; pedicels slender, up 

 to 4 lin. long. Calyx wide, subcampanulate, 4-5 lin. long, somewhat 

 fleshy, with a zone of numerous small glands just above the base ; lobes
