22 Voyage of the Wahlberg. [ZOE 
out of reach of the goats, and it is to be supposed that a botanist 
who could have reached this island before these animals, would 
have discovered many plants that must now always remain un- 
known, because they did not find an asylum on an inaccessible 
rock, : 
But goats are not the only exterminators of endemic species. 
for I searched in vain for Hespereleea at the exact locality where 
Dr. Palmer found it, and could only find a goat corral made from 
trees chopped down in the vicinity. 
The following list contains names of plants not previously 
reported from the island : 
Platystemon Californicus Benth. A recent introduction. 
Calandrinia maritima, Nutt. 
Microseris Lindleyi Gray. 
Beria coronaria Gray. A recent introduction about the usual landing. 
Beria gracilis Gray. Also recently introduced. 
Amsinckia intermedia F. & M. 
Orthocarpus purpurascens Benth. Introduced. 
Brodica lugens (Greene). Common along the slopes of Sparmann’s 
cafion. 
Aphanisma blitoides Nutt. 
Phalaris intermedia Bosc. 
‘he flora of the three small islands known as the San Benito 
Islands had previously been collected by Dr. Palmer* and Lieut. 
Pond,} who found twenty-five species. The endemic species 
Lavatera venosa, Hemizonia Streetsit and Mamillaria Palmeri 
are very abundant. The following additions to published lists 
are the result of a week’s search at a time when plenty of rain 
had brought forth an abundance of plants : 
Oligomeris subulata Bois. 
Phaseolus filiformis Benth. 
Petalonyx linearis Greene. 
Mentzelia involucrata Watson. 
Malvastrum exile Gray. 
Opuntia tessellata Engelm. 
Opuntia prolifera Engelm.
