Scalesia Arn. 



S. affinis Hook. f. (3), 212; Rob. (1), 216.— Charles Isl. : 

 bushes 5-6 ft. high at 550 ft. (no. 661). Indefatigable Isl. : 

 southeast side, bushes 7-10 ft. high around 600 ft. (no. 662). 

 Endemic. 



S. affinis Anderss. (1), 180, (2), 70, t. 7, f. 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 

 bushes near the shore (no. 664) ; southeast side, occasional 

 bushes in the vicinity of the shore (no. 663). Endemic. 



S. atractyloides Arn. in Lindl. Introd. Nat. Ord. ed. 2, 264, 

 443 (1836) ; Rob. (1), 216. — James Isl. : 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. 



S. Baurii Rob. & Greenm. (1), 141, 146; Rob. (1), 216.— 

 Duncan Isl. : abundant bushes on the upper parts of the
