The endemie genus consists of three closely-related species. In Engler and 
Prantl’s Natiirl. Pfizfam. the genus Nototrichium is merged with Psilotrichium, 
from which it differs, however, in the equal perianth lobes and tetramerous 
flowers. 
Only one species, NV. sandwicense, becomes arborescent; the other two species 
are shrubs. One of them occurs on Kauai, the other on Oahu, while V. sand- 
wicense or Kului oceurs on nearly all the islands of the group.

The Kului, which is usually only a shrub several feet high in the lowlands, be- 
comes a small tree of about 15 to 20 feet in height in the lower forest zone at 2000: 
to 3000 feet altitude. 
It is a handsome little tree and quite conspicuous by its silvery gray foliage and 
its pretty catkins which droop from the end of every branchlet. It is peculiar to 
the very dry regions and may be found as a straggling shrub where nothing else 
ean live. 
In Kona, Hawaii, especially near Puuwaawaa, it forms a regular hedge along 
the government road on the rough aa lava fields. On Molokai it grows on the 
western end in gulches, on the slopes of Mauna Loa, where it forms, together with 
the Nau (Gardenia Brighamii), the Ohe (Reynoldsia sandwicensis) and the Wili- 
wili (Erythrina monosperma), the last remnants of what was once a xerophytie 
orest. At Puuwaawaa, Hawaii, proper, it grows to a small tree about 15 to 20 
feet in height at an elevation of 3000 feet, besides also at Kawaihaeiuka (2500 
feet). together with Maua (Xylosma Hillebrandii) and the Mamani (Sophora 
chrysophylla). Tt also is not uncommon on Maui and Oahu. On the latter island 
it inhabits the arid regions of the Waianae Mountains. It occurs as a tree on the 
lava fields of Kau, and South Kona, on the slopes of Mauna Loa, Hawaii, and 
forms, in certain districts as Manuka, about 80% of the growth.
