12. A. ugandensis, Rendle. Stem erect about a foot high, 
sparsely branched; younger portion stellate-tomentose, hairs white, 
becoming glabrescent below. Leaves obovate with cuneate base, repand 
above, up to 24 in. long by barely 14 in. broad; apex blunt to obscurely 
emarginate; both surfaces stellate-tomentose, more densely beneath 
especially on the veins; petiole short, 3 lin. Jong or less. Flowers 
solitary, short-stalked ; stalk barely 4 lin. long; a pair of bracteoles 
arising at the base of the stalk, about 7 lin. long, narrowly linear- 
lanceolate with involute edges, and densely tomentose on the back. 
Sepals ovate, acute, dorsally keeled, the 3 outer about 7 lin. long, and 
almost concealing the slightly shorter narrower inner sepals, dorsally 
thickened in the middle line above the base. Corolla funnel-shaped, 
glabrous, 14 in. long; tube cylindric, a little over 3 lin. in diam., 8 lin. 
long, pale rose-purple ; limb very shallowly 5-lobed, white; midpetaline 
areas distinctly limited by two nerves on the outside, and suffused with

Near A. hyoscyamoides, from which it is distinguished by the broader tops of 
the leaves and smaller flowers. 
14. A. annua, Rendle. An erect: herbaceous annual (a complete 
specimen is 20 in. in height, with a stem about 2 lin. thick and 
unbranched, a second specimen consists of a portion of stem, evidently 
from a much larger plant, nearly 4 lin. in diam., bearing short leafy 
flowering branches). Stem hollow, terete, younger part clothed with 
greyish pubescence, becoming glabrescent and _ scabridulous below. 
Younger leaves elliptic with tapering ends, becoming oblanceolate t?
