It is a curious plant, coming near Acoroidee or Flu- 
viales, at least Naiades are to be considered as Triglochins 
reduced to one anther and one carpellary leaf. 
From the complete separation of the fertile from the bar- 
ren carpella, we may expect complete separation of these 
bodies. Indeed there is such a tendency to separation in 
all the envelopes, and they appear so very distinct, that 
we may also meet with a plant in which all the whorls 
are dislocated. In this tendency it obviously approaches 
Aroidez. In its ovule it has a close relation to Naias, which 
has them erect not pendulous, as Lindley states the whole 
order to have. "This a much more developed plant than most 
of the Naiades, which require subdivision. The large size of 
the anthers of these imperfect aquatic plants is curious, as well 
as the structure of their pollen. The situation of the fertile 
carpella is curious and shews that these have an inverse ten- 
dency to ordinary growth, inverse to that if the stamina 
which diminish inwards, these again approach to Aroidez, 
the bodies interposed between males and females being bar- 
ren, the lower are more like stamina and the upper like 
carpella, so that the order of growth in such plants is pre- 
cisely as it is in this
