Vo. IJ STEWART—BOTANY OF THE GALAPAGOS ISLANDS 95 
Ist.: James Bay, fringing a crater lake, south of the bay, the 
water of which is so saturated that a layer of pure white salt 
has crystallized out on the bottom; also occasional on the 
mountain side at 900 ft., (no. 1910). 
From the above it is seen that this tree is found under the 
most varied conditions, from halophytic to mesophytic, without 
any perceptible change in its general appearance. In many 
respects it is a very unpleasant tree with which to come in 
contact. The milky sap has a very strong peppery taste and 
will blister the parts which it touches, if not soon removed. It 
is also very unpleasant, and in fact dangerous, to be under these 
trees during a rain, for if the water from the leaves gets into 
one’s eyes, the sensation is very painful and the pain lasts for a 
considerable time. The fruit has a very pleasant odor when 
ripe, and resembles a small yellow apple in size and color, but it 
is. extremely poisonous, according to the inhabitants of the 
islands. The tortoises around Cape Rose, Albemarle Island, 
eat the fruit in great quantity; but we found in cleaning some 
of these tortoises for specimens, that this diet had weakened 
the tissues of the alimentary canal greatly. But little vegeta- 
tion is found under the trees of this species, as a rule, a condi- 
tion which is probably brought about by the dense shade.
