thrives in company with many other rare trees peculiar to that small area, such 
as Pelea, Xanthoxylum, Bobea, Pittosporum, Pterotropia, Tetraplasandra, ete. 
Owing to its scarcity, it is unknown to most of the old natives, who have heard 
of it only in rare instances from their ancestors. 
The wood, which is very hard and tough, has not been made use of by the 
natives, as far as can be ascertained. The bright scarlet fruit flesh is eaten by 
the natives, as well as the kernel of the seed, and are not altogether unpleasant 
to the taste. 
The Mahoe is endemic to the Hawaiian Islands, and is remarkable for its 
fruits, which are the largest in the genus. 
The name Mahoe, meaning ‘‘twins,’’? undoubtedly refers to the double fruits, 
which are not uncommon in our Alectryon.

The genus Dodonaea consists of 46 species, 44 of which are endemic in Aus- 
tralia, including the cosmopolitan D. viscosa L., which can be found in all 
tropical countries. 
In Hawaii three species occur; the above-mentioned D. viscosa L., besides 
D. eriocarpa Smith, and D. Honipiord Hbd., the latter a shrub 2 to 4 feet high 
and peculiar to Molokai. Outside of the Australian and Hawaiian species, 
there is only one other species, D. madagascariensis Rdlk., which is peculiar to 
Madagascar. They are trees or shrubs, or also bushes. 
The leaves in the Hawaiian Dodonaea or Aalii, as they are called by the 
natives, are simple, usually covered with glands which secrete a resin.
