T, Anderson says the stem of his B. lancifolia was pruinose; 8. Moore says his 
B, alata differs chiefly by having the stem scarcely pruinose, but it has really the stem 
more than pruinose, As to the corolla-difference, when ‘[. Anderson says his corolla 
was funnel-shaped with a very short tube, I suppose that he means that the cylindric 
part of the tube was very short. 
45. B. cyanea, S. Moore in Journ. Bot. 1880, 265. Shrub
