MARLE Iszt.: Villamil, bushes and small trees, 1200-1500 ft., 
and inside of the crater at 2750 ft. Calyx 5-crenate, stigma 
entire, leaves as described by Hook. f., 1. c., (no. 3347). 
CHARLES IsL.: small trees on the steep inner wall of the main 
crater at 1700 ft. Calyx 5-dentate, stigma obscurely bilobed, 
leaves mostly ovate and glabrous, although a few are some- 
what elliptical, (no. 3347). CHATHAM IsL.: occasional bushes 
around 2000 ft. Calyx truncate, stigmas bilobed and entire 
on the same plant, leaves orbicular to obovate, somewhat at- 
tenuate at base, sparingly pubescent above, tomentose below, 
(no. 3348). Duncan IsL.: small trees at 1300 ft. Calyx 
somewhat truncate, obscurely dentate, stigmas entire, leaves 
orbicular to obovate, mostly glabrous, although some show a 
slight tomentum on the lower surface around the veins. Both 
the flowers and leaves are smaller than is usually the case in 
this species, a fact that may be due to the more xerophytic con- 
ditions around the top of this island where the specimens were 
found, (no. 3349). James IsL.: James Bay, small trees above 
2200 ft. Calyx 5-crenate, stigmas bilobed and entire on the 
same plant, leaves agreeing with Hooker’s description, 1. c., 
(no. 3350). In consideration of the above varied characters 
which the more abundant material has brought to light, it 
seems best to combine A. insularis Rob. with A. ellipticus Hook. 
f. It is another instance of a very variable species, examples 
of which are common on the Galapagos Islands. It is hardly 
likely that the above variations are of formal value, as the 
specimens from Charles Isl. show nearly as much variation 
from the typical A. ellipticus as do the specimens from other 
islands. Endemic.
