that a resident band of goats must often satisfy their thirst by 
eating succulent plants, and have already nearly exterminated 
the Cotyledons. There are no trees, but a few small bushes of 
Veatchia are found and a dozen specimens of Cereus Pringlei, 
ten to fifteen feet high, are scattered about. The vegetation is 
scant and the general appearance of the island is barren. Most 
of the plants grow also upon Cedros, and these, with a few be- 
longing to San Bartolomé Bay, constitute its entire flora, for 
there is not an endemic species. The rainfall of the season had 
been even less than that of the southern end of Cedros, conse- 
quently the annuals were small and few in number, and the col- 
lection not as large as it would have been at a more favorable 
time. The following list contains names of the plants found 
upon the island:

From Natividad to San Bartolomé Bay is a distance of about 
twenty miles, and here a landing was made on the mainland of 
the Peninsula. In 1839, H. M. S. Sulphur anchored in this har- 
bor, and the plants found at that time are listed in the Botany 
of the Sulphur. In 1889 Lieut. Pond, of the U. S. ship 
Ranger also collected some plants in the vicinity. Forms from
