Calla (Aroidere) ; Professor Nobbe thought that they belonged to 
Nymphteaceae. 
Dr. Potoni6, in a special paper on these fruit (op. rit.), figured 
and described them under the name Folliculites can'nafus (Nehring), 
on account of their close resemblance to the Folliculite. •* halteunonl- 
liPDiirnsis, Zenker, which he also figures. There can be no doubt 
as to the striking resemblance between the two figures given by 
Dr. Potonie; but hi.s figure of Folliculites is quite unlike the fruits 
supposed to belong to the same species ( = /•’. thalictroide *), which 
occur so abundantly at Povey Tracey and in the Isle of Wight. 
Zenker’s original figure of Folliculites is too bad to allow one to 
ascertain the generic characters ; but if his fruits were anything like 
the figure given by Dr. Potonie, it is difficult to understand how it 
has happened that the extremely different fruits from Povey Tracey 
and the Isle of Wight have been referred to the same genus and 
species. In the British specimens of “ Folliculites ” the seed is 
erect, not pendulous as in Poratloj-ocarfms ; but an additional 
complication comes in, for the internal structure of my examples 
of the so-called Folliculites from the Isle of Wight, though 
corresponding with certain specimens from Povey in the Museum 
of Practical Geology, is different from that of the specimens from 
Povey figured by Sir Joseph Hooker." The two British Oligocene 
fruits evidently belong to different species, if not to different genera. 
If the plant figured by Dr. Potonie is the true Folliculites of 
Zenker, the species found at Klinge and in Norfolk will probably 
belong to the same genus ; but I can trace no generic relationship 
between the well-known Folliculites of Povey and of the Isle of 
Wight and the plant from the Cromer Forest-bed, though the 
various forms under discussion may all belong to the same order. 
iSince the last- mentioned paper appeared Dr. Potonie has referred 
Folliculites (including Paradoxocarjms) to the Anacar discern. t It 
is not easy to see on what grounds this reference is made, and 
I still think that the most probable position is with the Naidaceae, 
close to Naias. If the relationship were with Anacardiacese, or
