PACIFIC SCIENCE, Vol. XI, October, 1957 
from New Caledonia has been compared with 
X. callistemon W. R. B. Oliver of New Zea- 
land. Differences in perianth members and in 
form of fruit mentioned by Oliver are con- 
firmed, but the sinus on the inner edge of the 
leaf is well-developed in both species and is 
not a distinguishing character. Hitherto- 
unmentioned differences are that the style at 
fruiting stage is thin and irregularly twisted 
in X. moorei , stout and stiffly erect in X. 
callistemon; in seeds of X. moorei the keel is 
echinate, in X. callistemon keel and well- 
defined inner faces are without processes. The 
montane habitat of X moorei in New Cale- 
donia is probably similar in some respects to 
the coastal cliffs of New Zealand offshore 
islands where X. callistemon grows. No mor- 
phological feature of either species suggests 
an explanation for the peculiar distribution of 
the genus, and of the New Zealand species. 
Garden plants provide supplementary infor- 
mation about X. callistemon , and in particular 
indicate that two forms may be differentiated 
on characters of the floral bracts.
