The flora of Guadalupe Island‘) 100 miles off the coast of Lower 
Californica, and rising from an oceanic abyss, is essentially Californian, as 
eikpuished from the Mexican flora to which belongs the vegetation of the 
intervening peninsula of Lower California and the nearby islands. Trees are 
numerous over much of the island represented by Pinus radiata (= P. insignis) 
which exists in groves on the high narrow ridge at the northeast extremity of 
the island, Cupressus guadalupensis, Funiperus californica var. osteosperma in 
irregular groups on the middle of the island, Ouercus tomentella and a palm: 
Erythaea edulıs. 
On ascending from the narrow beach to the plateau or table land 3,000 feet high the 
ee plants occur: Senecio Palmeri, Sphaeralcea sulphurea, Hosackia ornithopus, Convolvulus 
macrostegius, all endemic species associated with Brodiaea capitata.. The ee list so far as 
known comprises the plants peculiar to the island, as given by VAsey and Ros 2

b) Mainland Area. 
An examination of the vegetation of this area shows it to be distributed 
into several distinct formations among which the bog and strand formations 
are limited in extent owing to the topography of the country. Two territories, 
the coastal and interior, may be distinguished, separated from each other by 
the Cuyamaca, Palomar, Temecula ranges.
