inconspicuous ; veins loosely anastomosing and slightly raised beneath ; 
petiole rather stout, 4-8 lin. long. Flowers in terminal, shortly 
peduncled, many-flowered, dense, tomentose or pubescent corymbs 
(very rarely in elongate panicles with the habit of the tendrils) ; 
peduncle stout, rarely more than a few lines long; bracts small, ovate, 
acute or obtuse, like the very short pedicels densely pubescent to 
tomentose. Calyx pubescent to tomentose, about 1} lin. long; sepals 
ovate, subacute or obtuse. Corolla yellow near the mouth, otherwise 
white, sweet-scented, rather variable in size; tube slender, slightly 
widened below the middle, densely pubescent to tomentose without, 
usually 8-11 lin. long; lobes linear-oblong or more or less spathulate, 
as long as the tube or slightly longer (rarely to 15 lin. long), 23-5 
lin. wide, pubescent without towards the base. Anthers linear-oblong. 
Ovary truncate, densely tomentose in the upper part. Style and 
stigma 2} lin. long, the latter cylindric, shortly bifid. Fruit more or
