S. affinis Anderss. (1), 180, (2), 70, t. 7, £. 3; Rob. (1), 
216.—INDEFATIGABLE ISL.: north side, low bushes 2-3 ft. high 
in lava crevices near the coast (no. 665) ; northwest side, low

S. atractyloides Arn. in Lindl. Introd. Nat. Ord. ed. 2, 264, 
443 (1836) ; Rob. (1), 216—JAmes Ist.: James Bay, bushes 
5-7 ft. high on the borders of recent lava flows, where it often 
grows to the exclusion of all other large vegetation, (no. 666) ; 
northeast side, bushes 4-8 ft. high on lava beds near the coast 
and above 700 ft. The leaves of the specimens from this local- 
ity are more scabrous and less pubescent on the lower surface 
than are the specimens taken in the vicinity of James Bay. 
The specimens agree with the rather brief description of this 
species, except that the heads are considerably smaller, (no. 
667). Endemic.
