126 Dr. GnoDENOUGH and Mr. Woodward'j Ohfervallom an 



with a ftrong partition running up the middle, anJ cluflcrs of feeds 

 adhering to the fides of the pods on the infide. In the hollow 

 cellular pods, traces of this difTepiment or partition are to be 

 obferved; one largifli and feveral very fmall filaments running 

 throughout longitudinally, and conne£ling all the cells. Whether 

 thefe cavities arife from their having fhed their feeds, or from the 

 abortion of them, may be an obje£t worthy of the attention of 

 thofe who have an opportunity of watching them through the 

 feveral ftages of their growth. It is obfervable that the leaves, as 

 they arc called, have all a rib or nerve paffing up the middle; 

 when the fructification takes place and the leaf fvvells, this rib be- 

 comes a partition line or diflepiment. 



The pods are very liable to be broken off by the force of the 

 waves. The plant often affumes a very difguifed form from this 

 accident; oftentimes not a fingle pod or leaf remains throughout 

 the whole frond. Here botanical experience affumes its due con- 

 fequence.
