some parts quite rocky. The smaller one is low and nearly level, 
with only a narrow strait separating it from the largerone. We 
were the first botanical collectors to set foot upon these islands, 
and entered upon our work with the eagerness of discoverers. 
On account of the proximity to the mainland it was supposed 
their flora would be the same as that of the neighboring coast, 
and two or three days collecting showed that this was mainly 
true, for only two or three strictly insular forms were seen. 
Seventy species of plants were collected, and doubtless more 
would have been found two weeks later, for the vegetation was 
not much advanced in the early part of March. The most com- 
mon plants were Calandrinia maritima, Cereus Emoryt, Mesem- 
bryanthemum crystallinum, Leptosyne maritima, Encelia California, 
Euphorbia misera and Brodiea capitata, all maritime plants abun- 
dant along the coast between San Diego and Ensenada. Hosackia 
Watsoni, Verbesina dissita, Solanum Palmeri and Physalis Greenet 
were the representatives of recently described and uncommon 
species. Hemizonia Greeneana was described from specimens col- 
lected on Guadalupe Island, which until now has been its only 
known habitat, and it was interesting to find this frutescent 
Hemizonia growing so plentifully over the larger of the Todos 
Santos Islands. ‘The only other representatives of the insular 
flora found, and these not in abundance, were Eschscholizia ramosa, 
an inhabitant of many other islands also and a Perityle. A few 
plants deserving of mention were Aalvastrum extle, Aplopappus 
Berberidis, Franseria chenopodifolia, Sonchus tenerrimus, Phacelia 
ixodes, Atriplex julacea. No trees grow upon these islands, and 
the only bushes of any size were Rhus laurina and R. integrifolia, 
generally alluded to in the publications of the coast surveys as 
“‘scrub oak.’’ 
The next landing was at San Martin, a small island situated 
west of San Quintin, in plain view from the Peninsula. It con- 
sists mainly of an old volcanic cone, four or five hundred feet 
high, having a well-formed crater, nearly one hundred feet deep, 
with the slopes toward the ocean covered with broken rock, over 
which near the base the sands have drifted. The guano poachers 
consider it a barren island and so it usually is, but our visit hap-
