Vol. I] STEWART— BOTANY OF THE GALAPAGOS ISLANDS 157 



Closely related to S. microcephala Rob., differing in the size 

 and shape of the leaves, the broader involucral bracts, and in 

 the variegated and glabrous achenes. The specimen is too 

 mature to show good floral characters. S. n. sp. ? Rob. (1), 

 220. — Albemarle Isl. : Iguana Cove, Snodgrass and Heller; 

 Tagus Cove, Snodgrass and Heller; Villamil, occasional trees 

 at 175 ft., abundant at 250-600 ft., smaller and less abundant 

 at 1300 ft. So far as is known this is the only arborescent 

 species of Scalesia found on this island, (no. 669). Plate IV, 

 figs. 4-6. Endemic. 



S. Darwinii Hook. f. (3), 211 ; Rob. (1), 216.— James Isl. : 

 James Bay, small trees 8-10 ft. high around 1000 ft. Con- 

 cerning this species Hook, f., 1. c, remarks as follows : "Char- 

 acteristic of the vegetation of James Isl., forming woods of 

 straight trees in the alpine or damp region. — Darwin, Ms." 

 Darwin evidently meant this statement to apply to 5. peduncu- 

 lata, as it is the only species of Scalesia that forms trees on this 

 island, (no. 670). Endemic. 



S. decurrens Anderss. (1), 182, (2), 71; Rob. (1), 216.— 

 Albemarle Isl. : Baur. Charles Isl. : low bushes abundant 

 in barren rocky places in the vicinity of the shore. The low 

 Scalesia bushes figured in Agassiz (1), PI. XX, belong to this 

 species. Endemic. 



S. divisa Anderss. (1), 179, (2), 70, t. 7, f. 1 ; Rob. (1), 

 217. — Chatham Isl. : Sappho Cove, bushes 2-4 ft. high on 

 lava beds near the coast (no. 672). Endemic. 



S. gummifera Hook. f. (3), 212; Rob. (1), 217.— Albe- 

 marle Isl. : Cowley Bay, bushes from the vicinity of the 

 shore and to 1200 ft. (no. 673) ; Elizabeth Bay, Snodgrass 

 and Heller; Tagus Cove, Snodgrass and Heller; Villamil, 

 bushes 3-6 ft. high in shady places, and on lava beds below 100 

 ft., (no. 674). Indefatigable Isl.: Academy Bay, bushes 

 in woodland below 100 ft., species somewhat in doubt. En- 

 demic. 



S. Helleri Rob. (1), 217. — Barrington Isl.: occasional 

 bushes 6-8 ft. high all over the island (no. 675). Endemic. 



S. Hopkinsii Rob. (1), 217. — Abingdon Isl.: common 

 bushes 6-8 ft. high from the vicinity of the shore to 1500 ft.
