Greece, must have acquired a fair idea of the destructive power 
of goats; but what is to be seen in Guadalupe far surpasses any 
anticipation. 
It would appear at first that annuals, unprovided by nature 
with a perennial or woody axis, ought to have been the first to 
disappear; but just the contrary has happened, probably owing 
to the circumstance that the cycle of evolution of an annual 
plant (more so in such a dry region) is exceedingly short, and 
coincides with the period of most plentiful production, so that 
there is much more chance of the ripening of an abundant crop 
of seed which, by its minuteness and unattractiveness, escapes 
destruction and assures a large reproduction of the species. 
Shrubs and perennials are exposed all the year round to the 
destructive teeth of the goats, and it is a well-known fact that no 
matter how hard and enduring the vitality of such plants, in the 
long run they are unable to survive the constant clipping of thei 
aerial parts. : 
Among the plants collected by myself in Guadalupe, annuals 
could not be numerous, owing to the season of the year, and very 
little was added to the island record. I was able, however, to 
secure a small plant of what appears to be a Heuchera, probably 
the unidentified species collected, in 1875 only, by Dr. Palmer, and 
a plant also of a Cotyledon—no species being described from the 
island. Among cryptogamous plants Parmelia physodes I,. var. 
enteromorpha Tuck., Usnea barbata 1,., Ramalina homalea 
Ach. are not to be found in the already published lists; all of 
them are known, however, on the mainland of California. 
The figures following the species are the serial numbers of 
the collection. 
Crossosoma Californicum Nutt. Only one specimen found 
with few flowers; in bloom about the middle of December. 
Growing on the almost inaccessible cliff of the lower circus 
east of the cabins. -(42.) 
Eschscholtzia Californica Cham. Plentiful in the same limited 
locality pointed out by Prof. Greene; positively perennial; its 
leaves clipped pretty closely by goats. (19.) 
_ Eschscholtzia elegans var. ramosa Greene. Rather plentiful 
not only along the beach north of the landing, as noticed by
