varieties are at the Bishop Museum. 
I have studied various specimens of the Lanai 
plants and cannot find sufficient difference from 
the Maui population to maintain it as an en- 
demic variety. 
We have records that Jules Remy made col- 
lections of this species on the island of Kahoo- 
lawe between 1851-1855 (Remy no. 559). 
Remy s specimens are not available and the 
plants can no longer be found on Kahoolawe, 
so a statement cannot be made regarding their 
taxonomy.
