Borraginaceae-Solanaceae. 
The Kou, whose Tahitian name is Jou, and is known in Samoa and Fiji as Tou 
or Hawanave and Nawanawa respectively, ranges all the way from the Hawaiian 
Islands to Madagasear, the Moluceas, and tropical New Holland. 
The wood is used by the Samoans for rafts, and the fruits for paste for their 
tapa clothing. The wood, which is much prized by the natives, is rather soft 
but durable. 
SOLANACEAE. 
The family Solanaceae is distributed over the tropical and temperate regions 
of the old and new world. The center of distribution is in Central and South 
America. In the Hawaiian Islands the family has one endemic genus which is 
closely related to a genus occurring in Brazil, but is not known from any other 
part of the world. Of the genus Solanum six species are also peculiar to these 
islands, but only one is a tree.

The genus eo. consists of 4 species and is peculiar to the Hawaiian 
Islands, where all of its species are known by the name Aiea. The genus 
Nothocestrum is closest related to the genus Athenaea Sendtn. which possesses 
about 14 species peculiar to Brazil. The Hawaiian genus differs from the latter 
mainly in the tetramerous flowers which are salver-shaped, and besides in the 
calyx, which does not become enlarged at the maturity of the fruit, as is the 
case in Athenaea.
