catch, are verj^ fugacious, small, yellow. The most peculiar thing 

 about the plant is the fruit. This, notwithstanding the earl}^ dis- 

 appearance of the flower, is quite abundant, and hangs on for 

 several months. It consists of a 4-sided pod from 3 to t cm. in length, 

 with 3-G cross septa, containing as many oblong beans, each of 

 which is imbedded in a light, greenish, dryish pulp. When dry the 

 pods are sharply angled, and the angles corky. From 4 to 7 pods 

 hang from a single peduncle. The stipules are even more fugaci- 

 ous than the petals, dropping off before the leaf is half developed.
