Heller. CHARLES IsL.: common near the shore and in loose 
ashy soil at 450 ft. (nos. 1490-1491). CuHatHaAm IsL.: An- 
dersson. Duncan Iszt.: (no. 1492). GarpNer IsL. (near 
Hoop Ist.) : abundant in loose soil mixed with fragments of 
lava (no. 1493). Hoop Ist.: Snodgrass and Heller. INDE- 
FATIGABLE Isit.: 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, Cuartes Ist. The family 1s 
doubtful (nos. 1494-1495). 
PORTULACACEAE 
Portulaca L. 
P. oleracea L. Sp. Pl. 445 (1753); Rob. (1), 145.— 
ABINGDON IsL.: common among rocks on the lower parts of 
the island (no. 1496). ALBEMARLE Ist.: 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). 
Cuar.es Is_.: 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 Ist.: Wreck 
Bay, common at 450 ft. (nos. 1500-1501). GaRrpNeER Ist. 
(near Hoop Ist.) : Snodgrass and Heller. Hoop Isi.: occa- 
sional at 250 ft. (no. 1502). NarsoroucH Ist.: 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, |. 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 Portulaca (?), 
were found on ABINGDON, BARRINGTON, BRATTLE, CHARLES, 
Jervis, and WENMAN IsLanps. It is the P. sp.?, mentioned 
by Robinson, |. c. 145. (nos. 1504-1510).
