Agave Shawii Engelm. Many plants were in full bloom. Dr. Palmer 
notes the presence of two Agaves, but it seems that this is the only species 
and that the spines of the leaf are very variable. A. Sedastiana Greene of 
Cedros Island is the same. This is the common Agave of the western 
coast of Baja California, between Santa Domingo and San Diego. 
From the San Benitos to Cedros Island is an afternoon sail 
with a good wind. Several collectors have visited Cedros, but 
as it is a large island no one has searched it perfectly. At this 
time the vegetation of the northern portion was as green and 
abundant as possible for this region, but the southern part had 
received a smaller rainfall and was very dry. The plants of the 
following list were collected, and have not before been reported 
from the island : 
Delphinium cardinale Hook. Galium aparine Vaill. 
Capsella Bursa-pastoris Moench. Beria gracilis Gray. 
Thysanocarpus laciniatus Nutt. Gnaphalium sp.

Bowlesia lobata, R. & P. 
Between Cedros and San Bartolomé Bay lies the island of 
Natividad. Previously it had been visited by no botanical col- 
lector. It is much smaller than Cedros, and the highest eleva- 
tion, about five hundred feet, is not to be compared with the 
mountains of that island. There is no fresh water upon it, so
