Vor. I] STEWART—BOTANY OF THE GALAPAGOS ISLANDS iN Sy/ 
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 Isx.: 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 Ist.: 
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 S. peduncu- 
lata, as it is the only species of Scalesia that forms trees on this 
island, (no. 670). Endemic.
