1 38 Flora of Guadalupe Island. [zoe 



Qziercus tomcntella Kngelm. 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 cupulae 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, (i.) 



Muhlejibergia debilis Trin. Only near the landing, on the 

 beach as well as the banks and bed of the canon. (34.) 



Polypogon vionspeliensis Desf. Plentiful only on saline soil 

 around the springs near the corral; goats and donkeys appear to 

 dislike it. (35 ) 



Cupress7is Guadahipensis 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.) 



Pimis insignis var. 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
