OTHER PLANTS REPORTED TO BE TOXIC 
Tn addition to those plants discussed in detail, certain other plants in 
the Virgin Islands are strongly suspected to be toxic. These species 
are listed on page 91. Some of these plants are also capable of causing 
a ay injury, for example, Monkeypuzzle (Huphorbia lactea 
aw.). 
Since many of these species came to the attention of the authors 
during the later stages of this study, they were not included in the 
chick-feeding test. Their reported toxicity or their close relationship 
to plants known to be poisonous, warrant their listing in this study. 
There are, undoubtedly, still other plants in the Virgin Islands which 
are toxic but as yet not suspected.
