- sandwicensis, various Sideroxylons and others. On Hawaii the writer found a 
small tree on the lava fields of Puuwaawaa, elevation 2000 feet, North Kona, 
while on Oahu it is recorded from Nuuanu and the dry forehills of Makaleha. 
The wood of the Naw is whitish yellow. The yellow pulp of the fruit was em- 
ployed in dyeing tapa, or kapa, yellow.

The Nanu or Nau, unlike the afore described, is a tall tree reaching a height 
of 20 to 40 feet with a rather large broad crown. The branches are more or 
iess horizontal in large trees; the trunk is short. The leaves which are larger 
than in the foregoing species are light green and covered as with a layer of 
varnish due to a glutinous substance which exudes from the young shoots. The 
large sweet-scented flowers are terminal and single and have no flower stalk. 
The fruit, which is quadrangular, is crowned by four wings, which are the per- 
sistent lobes of the calyx, a characteristic which is absent in the other Hawaiian 
u 
The Nanu or Nau may be found on the slopes of Tantalus and especially in 
Palolo Valley on Oahu, where it is a smaller tree, while on Molokai back of 
Kaluaha large trees can be found in company with Acacia Koa (Koa), Bobea 
elatior, Straussia Kaduana, ete. It grows on the leeward sides of some of the 
islands and also in the rain forests on the windward sides, as for example on 
Maui, where it is scattered between the valleys of Waikamoi and Honomanu 
on the northern slope of Haleakala, where the rainfall is exceedingly large, as 
well as on Kauai in the forests of Hanalei. Like the former it is endemic to the 
Hawaiian Islands; both species were discovered by Horace Mann and also de- 
seribed by him in his ‘‘ Enumeration of Hawaiian Plants’’; the former he named 
in honor of his companion, Prof. Wm. T. Brigham, the latter for the French 
Botanist Jules Remy. 
The glutinous leaf buds were used by the natives as a cement, and the yellow 
fruit-pulp for dyeing purposes.
