12. A. ngandensis, 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 2-i- in. long by barely 1^ in. broad ; apex blunt to obscurely 

 emarginate ; both surfaces stellate-tomentose, more densely beneath 

 especially on the veins ; petiole short, 3 lin. long or less. Flowers

Near A. Jiyoscyamoides, 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 to
