FLORA OF THE GALAPAGOS ISLANDS. 245 
BaRRINGTON ISLAND. 
Barrington is a small island about 8 km. long, lying between Inde- 
fatigable and Chatham. It rises only 277 m. above sea-level, and 
possesses only a xerophytic type of vegetation, with no ferns, no 
sedges, no Piperaceae, and only two Leguminosae. The island has been 
visited by Dr. Baur and by Messrs. Snodgrass and Heller, but only 39 
plants have been secured there. Of these but one Scalesia is confined 
to the island. The thorny Discaria, the Sealesia, just mentioned, 
Croton Scouleri, Cordia lutea, C. Hookeriana, and Maytenus obovata, 
together with a large and abundant Opuntia, are its shrubby and arbor- 
escent species, the other plants being herbs of a decidedly xerophytic 
type, grasses and Huphorbiaceae predominating as to number. Of its 
40 species, 26 occur upon Charles and Chatham Islands, while but 18 
have been found on the nearer Indefatigable. Leptochloa mucronata of 
South America, collected on Barrington, is not known to occur on any 
of the other islands of the archipelago. 
BInDLOE ISLAND. 
Bindloe lies with Abingdon and Tower to the northward of the other 
chief islands. It is roughly elliptical and about 15 km. long, rising to a 
height of only 250 m. It appears to have been visited for botanical 
purposes only by Dr. Baur, 4-5 September, 1891, and Messrs. Snod- 
grass and Heller, 29 June, 1899. Only 42 different plants have been 
collected or recorded there, and only 1, a mere leaf form of . Castela 
galapageia, is peculiar to the island, although the continental Canavallia 
obtusifolia, found upon Bindloe, has as yet been collected upon none 
of the other islands. Messrs. Snodgrass and Heller report a gigantic 
Cereus as rare on Bindloe; only one individual was seen. The Opuntia 
of Bindloe is low, only 3 to 9 dm. in height. More than half the plants 
of Bindloe oceur upon Charles, Chatham, and Albemarle respectively, 
While the proportion found on Abingdon and Tower is considerably less, 
and but a single plant of Bindloe has been found on Culpepper and 
Wenman. 
BrRaTTLeE ISLAND. 
Brattle is a small islet close to the southeastern shore of Albemarle. 
It forms, according to Dr. Baur, the remains of a single voleano, the 
southeast part of which has been nearly destroyed. The island has 
never been botanically explored. Dr. Baur made repeated efforts to 
land upon it, but was baffled by the precipitous shores. From his
