June 1917. Plant of 6-10 inches. Flowers yellow. On dry 
rocks. G. Forrest, No. 14,537. ; 
It is with some regret that one adds another to the many species 
of the Japonica group which have narrow pointed leaves, but the 
present plant appears quite distinct from any of those previously 
described. It produces a grove of annual ascending stems from 
a decumbent base, after the manner of S. Alfredi or the American 
S. mexicanum. The material is poor, all the leaves having 
dropped off, but a figure of a shoot is given restored as far as 
possible.
