T. Anderson says the stem of his IJ. lancifolia was pruinose ; S, Moore says his 

 B. (data differs chiefly by having the stem scarcely pruinose, but it has really the stem 

 more than pruinose. As to the corolla-difference, when T. 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 

 much branching; nodes slender, long, full of cystoliths, with two 

 opposite lines of minute curved white hairs, soon glabrate. Leaves 



1 by \ in., sessile, tip triangular, base narrowed, when mature with 

 scattered hairs above or nearly glabrous. Flowers solitary ; bract 

 ^ in. long, linear. Posticous sepal J by J— I in., entire, elliptic, sub- 

 acute, reticulate-nerved, minutely hairy ; anticous calyx-segment nearly 

 similar ; 2 inner sepals J in. long. Corolla intense blue {S. Moore) ; 

 tube J in. long, slender; limb as long as the tube.
