RESULTS AND DISCUSSION 
Table 1 lists the results of the alkaloid tests 
which were carried out on 29 plant species, rep- 
resenting 26 genera and 23 families. The 5 
species which gave positive tests ( + or + + ) 
with all six reagents are listed in Table 2. 
Table 3, which supplements Part I of this 
series, lists the results of the alkaloid tests which 
were carried out on 18 plant species, represent- 
ing 16 genera and 13 families. 
Results from Part I are included with the 
present results in the following analysis. 
To date, 125 plant species, representing 94 
genera and 57 families, have been tested for 
alkaloids. This constitutes approximately 10 per 
cent of the native Hawaiian flora. 
It is worth noting that the endemic genus 
Straussia has given quite variable results even 
among specimens of the same species. This 
variability would suggest that a botanical revi- 
sion of this genus is in order.
