This species exhibits extreme variation, 
especially in the leaves. The leaves are of 
various shapes, with a great number of inter- 
mediate forms, and they range in size from 
14 X 5 cm. to 2 X 1.5 cm. The obovate leaf 
with an obtuse apex is most frequently en- 
countered, but even on a single branch with 
leaves predominantly of this shape, others 
with ovate leaves and acute apices may be 
found. Of all the characters the flowers are 
the most constant. 
No combination of characters was found 
on which a separation of the various forms 
could be based. Any attempt at reclassifying 
the group always disclosed intergrading forms 
which rendered the system impractical. 
The absence of this widely distributed spe- 
cies on the island of Hawaii is peculiar. Rock 
(1913^) lists this species as occurring "on all 
islands of the group,” but no single collection 
of it was found from Hawaii.
