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 again 
slightly widened, delicately velvety below the stamens within, not 
twisted ; lobes obovate-oblong, slightly oblique, acute, 44-5 lin. long. 
Stamens inserted above the middle of the corolla-tube; anthers 
scarcely 14 lin. long, tips scarcely exserted, tails rather short. Disc

10. 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, 14-24 in. broad, papery; secondary nerves 
very oblique, gently curved, 6-7 on each side ; petiole slender, $—1 in. 
long. Inflorescences terminal from the youngest branch-forks, few- 
flowered, umbelliform, multibracteate ; peduncle slender, 14 in. long ; 
bracts persistent, crowded at the base of the pseudo-umbel, oblong, 
acute, 46 lin. long; pedicels slender, up to 4 in. long. Calyx sub- 
campanulate, 7-8 lin. long, with a transverse zone of scanty small 
glands somewhat above the base; lobes oblong, obtuse or shortly

towards the mouth, 7-8 lin. long, twisted, pubescent on the filamental 
ridges, otherwise glabrous within ; limb rotate; lobes obovate-elliptie, 
6-7 lin. long, crisp, brown when dry, Stamens inserted above the 
middle; anthers 3 lin. long, tips scarcely exserted, tails long. Dise

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
