 Sp. PI. ii, 618 (1753). 



Very slender and depauperate, apparently with cleistogamons llowers. The same 

 form has also been collected in Nebraska by Rev. J. M. Bates, of Valentine. Custer, 

 altitude 1,700 m., August 20 (No. 912). 



Scrophularia nodosa occidentalis, var. nov. 



Tall, 1 to 1.5 111. high, glandular, especially on the upper part of the stem; leaves 

 ovate or slightly heartshaped at the b.ase, doubly and sharply serrate or incised; 

 petioled, with fascicles of smaller leaves in the axils; panicle with short l)rauches; 

 sepals rounded-elliptical, obtuse, slightly margined; corolla lurid-greenish, gibbose 

 at the base; sterile stamens very broad, kidney-shai)ed on a claw. 



It differs from S. nodosa jiroper and S. nodosa marilandica in being glandular and 

 in the sharp serration of the leaves ; from *S'. calif ornica in its larger tiowers, sharper 

 serrations, stout habit, and the form of the sterile stamen; from all three in the 

 more gibbose corolla. No. 997, Sukadorf seems to belong to the same variety.

Pentstemou jamesii Benth. in DC. Prodr. x, 325 (1846). 



My specimens are like Fendler's No. 575. This, with his No. 579 and the original 

 specimens of James, are the only ones cited by Gray in his synopsis of the genus 

 in the Proceedings of the American Academy.' I think Watson's No. 778, named 

 P. cristaius, should also be referred to this species. Table-land : Hot Springs, altitude
