27. S. lophanthoides. Stem tall, 1 m. or so high, glabrous, or 

 minutely pilose at the tip; internodes 1 to 2dm. long: leaves broad- 

 ovate, short-acuminate, glabrous above, villous beneath on the nerves, and 

 especially along the midrib, finely crenate-serrate, on slender petioles 

 3cm. or less in length: peduncles 1.5 cm. or less long; racemes dense, 

 the primary ones 1.3 dm. or less in length, 1.5 cm. thick : bracts brownish, 

 ciliate-margiued : calyx viscid, pilose on the strong nerves, in authesis 

 5 to 6 mm. long, slightly etdarged at the throat, with broad-deltoid sub- 

 ulate-tipped lobes: corolla blue, slightly viscid, 1.2 to 1.4cm. long, the

 (Species with exceptionally large flowers, but with their affinities here 

 are S. heterotricha, S. flaccida, S. cedrosensis, S. semiatrata, and S. sidae- 

 folia with corollas fully 2cm. long; S. anyustifoha with corolla 2.5 cm.

 slightly branching stems : leaves linear, lanceolate, or narrowly ovate- 

 elliptic, narrowed cuneate or rounded-truncate at base. 



* Bracts orbicular, acuminate, about equalling the calyx, persistent : verticels 

 becoming remote : calyx campanulate, green, strongly nerved, suhinflated,
