On the Island of Molokai is a very narrow leaved form, with linear lanceclate 
very acuminate leaves, which are viscous; and with small pink flowers. It 
grows on all the islands of the group, from high elevations down to near or at 
the sea-shore, where it forms globose tussocks with salty fleshy leaves. 
The Naio or Bastard Sandalwood is a very handsome tree which reaches a 
considerable size. Its thick bark is of « dark gray color and deeply irregularly 
corrugated. It inhabits all the islands of the group and according to Hille- 
brand is supposed to reach its best development on the high mountains of Ha- 
waii, Mauna Kea and Mauna Loa, up to 10,000 feet elevation, which, howeve7, 
is not the case. Next to Ohia and Koa, it is one of our most common forest 
trees, growing at all elevations from sea level, where it is a small shrub 2 feet 
high, up to 10,000 feet. On the Island of Maui, in the dry forest back of Ma- 
kawao (elevation 2500 feet), as well as at Auahi, southern slopes of Haleakala, 
it attains its greatest height and diameter of trunk; trees of 50 to 60 feet with 
trunks of more than 3 feet in diameter are not uncommon. It prefers the lee- 
ward sides of the islands, especially the aa lava fields, regions with very little 
rainfall, as well as the high mountains of Mauna Kea, Mauna Loa, Hualalai and 
Haleakala, where it forms the upper forest zone together with the Mamani (So- 
phora chrysophylla), Raillardia, Coprosma, and Styphelia, reaching a height of 
about 20 feet, and withstanding heavy frosts. At the lower levels it is associ- 
ated with the Maua, Holei, Aalii, Kauila, Uhiuhi, ete. Hillebrand in his flora 
says that it is wanting on Molokai. The writer, however, found it very abundant 
above Kaunakakai, on the open dry ridges at Mapulou, where it grew together 
with Koaia and Alaa. The tree is glabrous throughout, has from narrow lance-
