 This is a lofty tree, and the handsomest in the whole equi- 

 noctia flora, abounding with thick shady bunches of leaves, 

 and large handsome purple and white flowers, every where 

 mixed with them. The flowers open at night, and fall at 

 sun-rise : the birds pluck them off, and the ground about 

 these trees is perfectly covered with them. The seed mixed 

 with bait, inebriates fish in the same manner as the Coculus- 

 indieus, &c. It grows within the tropics, especially on the 

 shores of the ocean, and at the mouths of rivers in the East 

 Indies, from the southern coasts of China, through the Mo-

 than the stamina ; stigma obtuse, nodding. Pericarp : cap- 

 sule ovate, compressed, acuminate, two-celled, two-valved ; 

 partition contrary to the valves. Seeds : numerous, angular, 

 small. ESSENTIAL CHARACTER. Calix : two-lobed, emar- 

 ginate, coloured. Corolla , coloured less than the calix :
