Shrub or treelet 1-38 m. tall. Trunk to about 5 em. 
in diameter near base. Bark thin, cracked lengthwise, 
roughish, greyish brown. Branches few, lax, spreading, 
naked. Branchlets subterete, 5—6 mm. in diameter, gla- 
brous, light brown to ochraceous, shiny, outer bark thin, 
splitting longitudinally and shedding in thin flakes, in- 
ternodes mostly 1-3 em. long. Leaves scattered along 
branchlets or somewhat crowded, short petiolate, elliptic 
to lanceolate, sometimes obovate, apically obtuse with 
short, subfaleate acumen or acuminate, cuneate to obtuse 
at base, blade 20-30 cm. long, 7-12 cm. wide, glabrous, 
smooth, subcoriaceous, dull, dark green above, pale green 
beneath, lateral nerves 8-10, straight, spreading, arcu- 
ately anastomosing 2-8 mm. within margin, veinlets 
more or less conspicuous, reticulate; petiole short, stout, 
subterete, 5-10 mm. long, canaliculate above, glabrous, 
dark brown, roughish. Inflorescence corymbiform, ter- 
minal or axillary, usually few-flowered with 4-7 (rarely 
20) flowers, puberulent or glabrous, bracteate. Bracts 
lanceolate, concave, 1-2 mm. long, glabrous. Pedicel 
slender, terete, erect, 6-138 mm. long, glabrous. Calyx 
tubular-campanulate slightly inflated, 10-18 mm. long, 
4-6 mm. in diameter, subcoriaceous, glabrous, teeth 
short, broadly triangular, acute to blunt with short glan- 
dular acumen; calyx in fruit coriaceous, striately nerved, 
dotted with lenticels, to 13 mm. long. Corolla tube twice 
as long as calyx, cylindric, straight, fleshy, slightly di- 
lated and curved at apex, 22-25 mm. long, 8 mm. in 
diameter, glabrous: limb 25-30 mm. across, glabrous, 
sky blue to violet, fading to white, thickening at mouth 
prominent, fleshy, 5-angled, white, lobes subequal, the 
uppermost slightly larger, rounded, abruptly narrowed 
at base, strongly deflexed at anthesis. Stamens inserted 
in upper part of corolla tube; filaments subligulate, 
curved at apex, lower inner pair 2.5 mm. long, upper
