is ovoid, fleshy, of a red color and about half an inch long. It flowers 
from July to September. It is a native of India and China and ex- 
tends southward to Australia and Polynesia. In India it grows in 
the outer Himalaya up to an elevation of 4500 feet, but is now cul- 
tivated nearly all over the tropics for ornamental reasons. It is also 
known as Satinwood. The wood is light yellow, close grained, and 
exceedingly hard. It resembles boxwood, and has been similarly em- 
ployed. Quite a number of these shrubs may be seen scattered all 
over Honolulu in private premises as well as in parks. 
BURSERACEAE 
Canarium Nut Family. 
The only genus to be recorded as under cultivation in Hawaii is 
Canarium of which Canarium commune L., the Canarium or Pili 
Nut Tree, is the sole representative. It is a native of the Moluccas 
and Java. It is a slow grower but lends itself wonderfully for avenue 
or street planting, where durability and longivity rather than quick 
shade are required. The finest avenue in the world is the Canarium 
Avenue which leads into the famous botanic gardens at Buitenzorg in 
Java. An avenue of this wonderful tree would indeed be an asset 
to Honolulu. 
MELIACEAE 
Santol Family. 
The Santol Family is represented in Honolulu by several genera 
which will be treated below. Mention must be made of a species 
belonging to the genus Toona of which there is only a single tree 
in Honolulu. It is the Toona febrifuga (Forst.) M. Roem. a 
native of Java and India. The genus Toona and several of its 
species are not recognized in Index Kewensis, and Toona febrifuga is 
listed as a synonym of Cedrela Toona Roxb. which in fact is identi- 
cal with Toona ciliata Roem. Toona febrifuga has entire pointed 
leaflets, large racemes and large capsules covered with lenticels, while 
Toona ciliat.a=( Cedrela Toona) has short racemes and small, smooth 
capsules. 
It is a large tree fifty to sixty feet in height with long drooping 
branches. The bark yields a resinous gum, and the flowers a red 
and a yellow dye which is obtained by boiling the flowers. Medicin- 
ally the bark is used as a mild febrifuge. The tree w x as introduced 
by Dr. Hillebrand in whose residential grounds the original specimen
