The Lehua ahihi is one of the handsomest species of the genus Metrosideros. 
The fine bright green graceful foliage stands quite distinct from all the other 
species and varieties and certainly deserves specific rank. It can be found on 
Oahu at the lower elevation around Tantalus back of Honolulu, and in nearly 
all the neighboring valleys on their upper slopes at about 1000-2000 feet eleva- 
tion. When in full flower the slender branches are drooping and almost con- 
tinually in motion, whence its specific name.

This variety is peculiar to the summit ridge of Mt. Waialeale on Kauai, where 
it was observed and collected by the writer. It certainly is the most beautiful 
Metrosideros or Ohia lehua known to him. It only grows at a certain ridge at 
the summit of the mountain of Kauai where it forms pure stands with hardly 
any other tree around it. It is a small tree 25 feet high. Collected flowering 
and fruiting Sept. 24, 1909, Mt. Waialeale, Kauai, elev. 5200 feet, type no. 5083, 
in College of Hawaii Herbarium.
