1. The aquiferous system has a sylleibid-like or leuconoid organization, with eurypylous or Aphodal choanocyte chambers”

2. Indirect measures of ploidy level (number of chloroplasts per guard cell, stomatal size) indicate that aquiferous stomata could be endopolyploid relative to aeriferous ones.

3. This family is also characterized by a sylleibid-like or leuconoid aquiferous system harbouring eurypylous or Aphodal choanocyte chambers (Gazave et al., 2010)

4. Littoral's groundwater commonly keeps in the aquiferous system which is composed of multi-aquifer and feebleness dank layers, each layers' groundwater is exploited in various degree.
