138 Flora of Guadalupe Island. [ZOE 
Quercus tomentella Engelm. In the northwestern part of 
the island with the palms. The trees are fine specimens forty 
to sixty feet high, remarkable for the grayish color of the bark 
and the size of the leaves, which are glossy dark green on the 
upper surface and covered with a somewhat rusty tomentum 
beneath. (4, 5.) 
At the eastern part, right under the cliff of the inner circus 
grow some trees in two different localities more than a mile apart, 
which if not specifically distinct appear at least to be a very 
different form, not only by the leaves, but also by the bark which 
is darker and corky. ‘These trees are rather stunted and branching 
from the base. No acorns or cupulz were to be found. A few 
scattered oaks were also observed near the north end, and it is the 
only tree to be seen at the southern part. They appear not to 
grow above 1800 or 2000 feet elevation. 
Erythea edulis Wats. Northwestern part of the island, the 
principal grove not less than one mile and a half long by half to 
one mile in breadth. There, and in the few other parts where 
palms are still growing in small numbers their range in altitude 
appears to be between three hundred and a thousand feet. A 
few expanded flowers were to be found already at the beginning 
of December, but the general blossoming takes place in January 
and the fruits are said to ripen in April. (1.) 
Muhlenbergia debilis Trin. Only near the landing, on the 
beach as well as the banks and bed of the cafion. (34.) 
Polypogon monspeliensis Desf. Plentiful only on saline soil 
around the springs near the corral; goats and donkeys appear to 
dislike it. (35.) 
Cupressus Guadalupensis Wats. Centre of the island and 
around the springs; very variable in habit, in color, as also in 
the size and shape of the cones. The principal grove on the 
higher central plateau covers an area of not less than two or three 
Square miles. (3.) 
Pinus insignis yar. binata Engelm. Only on the northern 
and northwestern part of the island, the finest trees growing 
amongst the palms. On some of the trees both the abnormal
