246 PROCEEDINGS OF THE AMERICAN ACADEMY. 
account (2), 236, we learn that the island is green as though covered 
with vegetation, that many ravines run down from the upper part, and 
that it is the breeding place for numerous sea-birds. Messrs. Snodgrass 
and Heller sailed within a few hundred yards of Brattle and report it a 
low, steep, and sterile rim of a tufa crater, the only vegetation being a 
scattering growth of Croton bushes. 
Grossman Islands are similar small rocky islets, on which no plants 
have been observed. 
CHARLES OR FLORIANA ISLAND. 
Charles is one of the five larger and higher islands, and with the pos- 
sible exception of Chatham has been the most fully explored botanically. 
It has yielded the largest number of plants, namely, 267. Of these 33 
are peculiar to it, and 105 to the archipelago. Charles was at one time 
inhabited by a penal colony from Ecuador, and in its flora shows a greater 
number of obviously introduced plants than are found on any of the other 
islands except Chatham. Of the 267 plants found on Charles 126 occur 
also on Chatham and 100 on Albemarle. According to Baur (2), 239, 
the appearance of Charles is quite different from that of Chatham, the 
hills being more rounded. He also states that there are no large forest 
trees on Charles. The desolate coast of Charles at Black Beach is fig- 
ured by Agassiz (1), t. 19, 20, and the copious vegetation on the way 
to the hacienda, t. 21. 
CHATHAM ISLAND. 
Chatham being the most easterly of the islands, is of course the nearest 
to the mainland. It is relatively large and fertile, and the only one of the 
group which is now inhabited. Portions of it are covered by forests of 
large trees, and in other parts are high arable plains, well shown by 
Agassiz (1), t. 17. When Baur visited the island in 1891, he found 
two hundred and ten acres under cultivation. The plantations are owned 
by Mr. Cobos, to whose courtesy and hospitality the visiting naturalists 
have been repeatedly indebted. Chatham has been relatively well ex- 
plored, 231 plants having been found upon it. Of these, 24 are peculiar 
to it, and 82 exclusively Galapageian. Notwithstanding the habital 
differences spoken of by Baur (2), 230, the flora of Chatham possesses 
the largest common element with that of Charles. <A giant cactus (Cereus 
sclerocarpus ?) with red egg-shaped fruit is mentioned by Baur. This is 
doubtless the one which appears in Agassiz’s Plate 16.
