 solitary in the axils and condensed at the ends of the branches in somewhat 

 capitate clusters of 2, 3, or 4; corolla-tube scarcely exserted from the narrowly 

 campanulate or in age somewhat urn-shaped calyx; calyx-teeth little unequal; 

 apex of capsule narrow, somewhat curved, exserted.

 teeth; corolla bright scarlet, 1^4 to 2 in. long, the throat yellowish with crim- 

 son lines, the tube little exserted from the calyx; upper lip of corolla erect,

 deeply 3-lobed, the lateral lobes reflexed, the middle lobe spreading; capsule 

 chartaceous. 



Stream beds, rivulets, or springs of the Coast Ranges and Sierra Nevada. 

 June-Oct. The strongly prismatic angles of the calyx follow out into tin 1 

 teeth in such wise that the teeth are conduplicate ; each lobe of the corolla 

 is rather strongly emarginate; anthers mostly densely hispid-ciliate; filaments 

 dilated at insertion.
