630 STR YCHNOS 



Strychnos L. Loganiaceae. 200 trop. Some, e.g. S. Nux-vomica L. 

 (India, Ceylon), are erect trees, others are climbing shrubs, with curious 

 hook-tendrils. The hook is a modified axillary shoot ; the 1. in whose 

 axil it arises usu. becomes a scale 1. If the hook catch upon a support 

 it twines close round it and thickens and lignifies (cf. Clematis). Other 

 sp. have axillary thorns. A few have a i-loc. ovary with free-central 

 placenta. Fr. a berry ; the flesh is harmless, but the seeds are exceed- 

 ingly poisonous, owing to the presence of strychnine in the seed-coats. 

 From these seeds the alkaloid is chiefly obtained. S. toxifera Schomb. 

 (S. Am.) yields the famous wourali or curare poison, with which the 

 S. Am. Indians poison their arrows; it is obtained from the bark by 

 scraping and maceration in water. The seeds of S. potatorum L. f. 

 (clearing nut) are used to purify dirty water for drinking. They are 

 rubbed on the inside of the vessel, and cause precipitation.
