DICOTYLEDONEAE. 
ULMACEAE. 
The family Ulmaceae is at present to be found nearly everywhere in the 
tropical and extra tropical regions, though they are only sparingly represented in 
the western part of North America, and are entirely absent in the prairie re- 
gions as well as in the Asiatic and African deserts, and also in South and West 
Australia. As far as Hawaii is concerned, the genus Trema is alone of interest. 
The family consists of 13 genera, with about 117 species. 
TREMA Lotr. 
(Sponia Comm.) 
Perigone of the male flowers 5-, rarely 4-parted, as many stamens as segments. Ovary 
sessile, with permanent styles. Drupe small eet or subglobose, crowned by the styles, 
oh enclosed in the Nae Seeds with a fleshy albumen. Embryo curved or spiral 
ith narrow cotyle Tree sioate with short spain Basis or pinnately nerved 
ares and ie poate monoecious or dioecious. Flow ery small. 
This genus consists of about 30 species, which are all Sac shih, and occur 
in the tropies of the old and new world. The most common is T. amboinensis 
Blume, which occurs in subtropical and tropical Asia and Australia and the 
Hawaiian Islands.

Trema Se which has no Hawaiian name as far as can be ascertained, 
is a small tree, 20 to 30 feet in height, whose young branches are covered with 
a soft gray pubescence. As has already been remarked, the tree is not peculiar 
to Hawaii, but is found on nearly all the other islands of the Pacifie, as, for 
example, in Samoa, Viti (Fiji), Tahiti, ete., where the tree is much more com- 
mon than in Hawaii, and where it is also known by several native names. In 
Hawaii the tree has so far only been found in Manoa Valley and on the northern 
slope of Kaala, on Oahu, and also at Mapolehu, on the island of Molokai. 
Parts of the tree are used medicinally, mainly for their purgative properties, 
which are expressed in the Samoan names tio and wi; the most common name by 
which the tree is known in Samoa is fauwi, and on Tutuila the name fi’ovale is in 
use. The name fausoga occurs also in Samoa for this particular tree. From the 
bark of the fauui or fausoga the natives manufacture a strong fiber which they 
use for their fish nets.
