Vol. I] STEWART—BOTANY OF THE GALAPAGOS ISLANDS 65 



Heller. Charles Isl. : common near the shore and in loose 

 ashy soil at 450 ft. (nos. 1490-1491). Chatham Isl.: An- 

 dersson. Duncan Isl.: (no. 1492). Gardner Isl. (near 

 Hood Isl.) : abundant in loose soil mixed with fragments of 

 lava (no. 1493). Hood Isl.: Snodgrass and Heller. Inde- 

 fatigable Isl. : Andersson. James Isl. : Andersson. Sey- 

 mour Ids.^ north and south : Snodgrass and Heller. Widely 

 distributed on tropical shores. . 



Aizoacea (?) sp. Sterile specimens of bushes 4-5 ft. high 

 with succulent leaves were collected on Brattle Isl. and on 

 the beach at Cormorant Bay, Charles Isl. The family is 

 doubtful (nos. 1494-1495). 



PORTULACACEAE 



Portulaca L. 



P. oleracea L. Sp. PI. 445 (1753); Rob. (1), 145.— 

 Abingdon Isl. : common among rocks on the lower parts of 

 the island (no. 1496). Albemarle Isl.: Iguana Cove, 

 abundant on the sides of the cliffs above the cove (no. 1498) ; 

 Tagus Cove, common in tufaceous soil on the lower parts; 

 Villamil, abundant in open places in the lower parts (no. 1497). 

 Charles Isl.: common around 1750 ft. during the dry sea- 

 son; during the rainy season it occurs abundantly all over the 

 lower parts of the island, (no. 1499). Chatham Isl. : Wreck 

 Bay, common at 450 ft. (nos. 1500-1501). Gardner Isl. 

 (near Hood Isl.) : Snodgrass and Heller. Hood Isl. : occa- 

 sional at 250 ft. (no. 1502). Narborough Isl.: north side, 

 common in crevices in the lava (no. 1503). The fact that this 

 species is found on such unfrequented islands as Abingdon 

 and Narborough would seem to indicate that it might not have 

 been distributed by intercommunication among the islands as 

 suggested by Robinson, 1. c. At the time Dr. Robinson's paper 

 was written it had only been found on the more frequented 

 islands. Widely distributed. 



P. sp. ( ?). Sterile specimens of a species of Porhdaca ( ?),, 

 were found on Abingdon, Barrington, Brattle, Charles, 

 Iervis, and Wenman Islands. It is the P. sp. ?, mentioned 

 by Robinson, 1. c. 145. (nos. 1504-1510).
