Oleaceae-Loganiaceae. 
Kauai are exceedingly large and oblong acuminate. It flowers usually in March 
in certain localities, but the writer found the trees in South Kona on the lava 
fields of Kapua loaded with the ripe bluish fruits during the month of January. 
It is a graceful tree and reaches often a height of 60 feet, with a trunk of 3 feet 
in diameter; the bark is thick and very corrugated, often divided into oblong 
scales. It occurs on all the islands of the group, especially on the dry leesides 
from 600 to 4000 feet elevation. On Kauai it grows in the great Waimea Canyon 
and at Halemanu, as well as Milolii and in Kopiwai forest, where the writer met 
with handsome specimens. The biggest tree the writer saw in the Kipuka Puaulu 
on the edge of an old aa lava flow near the Voleano Kilauea, on the slopes of 
Mauna Loa, elevation 4000 feet. 
The wood of the Pua is extremely hard, close grained and very durable; it is 
of a dark brownish color with blackish streaks, exceedingly heavy and takes a 
most excellent polish. The wood was often used by the natives for various pur- 
poses such as adze-handles. In helping to shape the fish hooks, the Pua wood was 
used, as well as the rough pahoehoe lava rock, as rasps. 
LOGANIACEAE. 
g The family Loganiaceae, with its 31 genera and more than 370 species, is de- 
cidedly tropical; only few representatives are found outside the tropics, and 
only two genera are found distributed in the tropics of the whole world, while 
the remaining ones are restricted to certain regions. In the Hawaiian Islands 
only one genus (Labordia) of this family occurs, which is endemic.

The genus Labordia consists of numerous species, and is endemie to the Ha- 
waiian Islands. Only a few become trees, while the majority of them are 
shrubs inhabiting the middle forest zone along stream beds or in swampy 
grounds in dense shades up to an elevation of over 5000 feet. Only one or two 
occur on the forehills of the dry districts at the outskirts of the forests, as for 
example in Mahana Valley on Lanai. The native name of nearly all the species 
18 Kamakahala. The majority of the species have green flowers, while some have 
orange colored thick fleshy corollas. a 
H. Baillon in his treatise on the tribe of Labordia remarks that in his cama 
the Genus Labordia cannot be sustained. He goes on to say that owns a 
the imbricate and more often twisted corolla the genus should rather be ene 
fied under the family Apoeynaceae than Loganiaceae. ‘The existence of stipules
