Incertae sedis 



In the present state of knowledge there 

 are a number of named forms which it is 

 impossible to treat systematically. The 

 various generic designations Hsted below 

 may possibly have a certain value but in 

 any event their significance does not ap- 

 pear to be biological. The names Spor- 

 ites (H. Potonie, 1893), Pollenites, and 

 Sporonites (R. Potonie, 1931) cannot be 

 regarded as having systematic value. 

 Forms hsted in these groups have no es- 

 sential biologic features in common, no 

 type species are recognized, and no sys- 

 tematic treatment is feasible on this ba- 

 sis. A morphologic designation apparently 

 would have served as well to record the 

 lack of systematic information concern- 

 ing most material of this character. It 

 likewise seems impossible to attach any 

 generic significance to the names Verru- 

 cosa-sporites (Loose, 1934), Elongato- 

 sporites (Berry, 1937), Punctata-sporites 

 or Zonala-sporites (Ibrahim, 1933). Such 

 problematic forms as have been listed 

 under these names must await future dis- 

 position.

In addition, the following types of 

 Raistrick and Knox may be listed, for 

 they too are of uncertain afifinity at the 

 present time. Some of these seem to be 

 worthy of more appropriate classification.
