This agrees with the last in general habit, but is rather smaller, 

 especially thejiowers. The ste7n is roughish. Leaves broader, 

 less apt to turn black in drying, all of them generally quite en- 

 tire, as well as equidistant, each pair from the bottom of the 

 branch upwards being accompanied by a pair oijlowers, less 

 decidedly turned to one side, and by no means crowded into 

 spikes. Segments of the calyx lanceolate, longer than the tube. 

 Cor. half the size of the preceding, deep yellow, with some 

 orange or red spots about the mouth, which is open, not closed ; 

 the lower lip pointing downwards; upper elevated. Capsule 

 less pointed ; the valves reticulated with prominent veins. Seeds 

 sometimes solitary in each cell, but mostly in pairs.
