present in larger quantities in the fruit before it is entirely ripe. 

 Solanidin C;5.) H,.,, NOi, is also present. The symptoms are 

 stupefaction, staggering, loss of speech, cramps and sometimes 

 convulsions. Death is due to paralysis of the lungs, but few 

 cases are fatal. 



POPOLO (Solatium trifolium) 



This species is much more common than the foregoing, but is 

 also confined to the lowlands. It is an annual weed with small 

 whitish flowers and greenish black fruits (small berries). The 

 berries are poisonous but no cases of human poisoning have 

 been recorded. 



JIMSON WEED or THORN APPLES f Datura stramonium) 



A rank-scented, tall, narcotic herb with spiny ovoid-pointed 

 capsules and tubular- funnel-shaped purplish flowers. The seeds 

 of this plant are exceedingly poisonous and prove invariably 

 fatal when eaten. The alkaloids are atropin and hyoscyamin. 

 the active principle of belladonna. Persons have been poisoned 

 by sucking the flowers or eating the seeds. The symptoms are 

 nausea, dry, burning skin, dilated pupil, loss of sight, mania, 

 convulsions and death. Vomiting is not a common symptom. 

 The thorn apple occurs in waste places all over Honolulu and 

 makes its appearance usually after or during the winter rains ; 

 it is found on all islands. Mention may also be made of Datura 

 suaveolens and Datura arbor ea; both species are known in Ha- 

 waii as Angel's Trumpet. The large white pendant flowers make 

 them conspicuous and both species are poisonous. 



CASTOR OH^ BEAN (Ricinus communis). 



The well-known castor oil plant is very common about Hono- 

 lulu, especially in waste places. The seeds furnish the well- 

 known castor oil, a mild and safe purgative when refined. The 

 seeds contain 50% of oil and an acrid poisonous substance, and 

 three seeds have been known to cause death in man. The seeds 

 are ten times more purgative than the oil. Recently, in Hono- 

 lulu, a soldier died a few days after having eaten six seeds of 

 this plant. The oil is not poisonous, but the pulp contains an 

 acrid albuminous substance called ricin Cg Hg N.. O.. The seeds 

 have also caused death in horses. 



POINSETTIA (Euphorbia pulcherrima). 



The Poinsettia is also very poisonous, especially the latex or 

 juice, and gardeners have often been severely poisoned while 

 cutting the plants and handling them. A child is said to have 

 died on Kauai, due to poisoning caused by sucking freshly cut 

 stems of the Poinsettia.
