 Native of Java. From the capsule being 4-cornered it is pro-

 is perhaps a species of Myriophyllum, but differs from that genus 

 in the leaves being scattered.

Cult. The species of Ammannia being all annuals, and for 

 the most part natives within the tropics, the seeds of them must 

 be sown in pots, which should be placed in a hot-bed frame or 

 in a stove, and when the plants have grown to the height of 2 

 inches, they may be transplanted into other pots, 3 or 4 plants 

 in each ; these pots should be placed in the stove or warm part 

 of a green -house, placing each in a pan of water. Some of the 

 plants may also be planted out in the open ground, in a shel-
