In addition to this kind of leaves, there are others which are obovate 
slightly retruse mucronate. figure 3&; spatulate retruse, figure 3c; 
and broadly lanceolate, figure 3^^. The margins of many of the leaves 
are slightly re volute. 
The specimen from the northeast side of Indefatigable Island has 
no leaves which are distinctly oblong, as the bases are rather attenuate 
in nearly every instance. There are a few leaves, however, which 
approach in shape those described by Robinson, one of which is shown 
Fig. 4 
in figure 4a. Other kinds of leaves on this specimen are oblanceolate, 
figure 46; spatulate mucronate, figure 4.0; and cuneate, figure 4.d. 
Many of the leaves of this specimen have strongly revolute mar- 
gins, a condition that may be brought about by the loose nature of the 
soil and the extreme dryness of this part of the island. The upper 
surfaces of many of the leaves are wrinkled, a character which is 
present to a greater or less extent in many of the Academy specimens. 
It seems to vary with the age of the leaves as does the character of 
shininess. 
The armed specimen from the northwest side of Indefatigable 
Fig. 5 
Island^ has many leaves which are typical as is shown in figure 5a. 
Other kinds of leaves on this specimen are: oblong retruse, figure 5&; 
^ Owing to a typographical error this specimen No. 1749 was listed as being from 
the northeast side of Indefatigable Island in my former work on the Galapagos flora.
