From San Luis Valley, I have specimens (779) too old for satisfactory 

 determination, but which I doubtfully refer to this species. 

 . S. galericulata, L.(?) San Luis Valley. September. Too old to be 

 certain about. (781.)

LITH0SPER3IUM PILOSIJM, Xutt. Grant post-oflBce. July, 

 Mertensia oblongifolia, DC. Apex. This, one of our best marked 

 species of the genus, varies immecsely in nearly every character. I 

 find the unusual width of the filaments a reliable test; though often 

 wider, they are seldom narrower than the anthers. (709a.) 

 M. SiBiRicA, Don. Sixteen inches high, leaves all ovate-lanceolate; 

 lowest with i>€tioles two inches long ; stem-leaves with petioles one 

 inch long, and upper ones sessile; calyx-lobes obtuse, one-third as 

 long as the corolla-tube. (7096.) 



M. PANicuLATA^ Don. These specimens evidently were an accidental 



; doubtless intended for a srood if. Sibinca (\u thp. immpHi- 



species 



ate company of which they were growing). A deep shade caused 

 them to lengthen out, in search of sunlight, into the real paniculate 

 form ; to which I add, Vidi vivam spontaneam. (709.) The well- 

 marked M. brevisiyUij S. Watson, does not appear in this collection, 

 which is remarkable.

 Fruit with a single marginal row of prickles, of which (in my speci-

 others, (697.)
