859. Pothos scandens. — Panukka, I cannot conceive why this 

 plant is ranked among Aroideae, Acoraceae being considered 



' distinct. If this latter be really distinct, pothos belongs to it, 

 and is the transition to genuina Aroideae. The chief distinc- 

 tion between the orders is the absence of scales in the one, 

 and their presence in the other. But if we look at their 

 irregularity in number and disposition, and the obvious fact, 

 that they pass so gradually into the stamina, that they may 

 be considered as these organs in an abortive state, there 

 is no necessity at all for the separation. Mr. Brown classes 

 with his usual judgement Pothus and Acoraceee, as they now 

 stand, among his last section of Aroideae, Orontiacese. 



It is a curious fact that though the ovula differ in situation, 

 in Acorus they are pendulus, in the present plant erect, that 

 in both the foramena point to the base of the fruit, or rather 

 ovarium. The reduction of the ovula to one coat appears 

 constant in Aroideae. The ovarium is 3 celled and as in
