who in his Genera (liv. 5 and 6, p. 107), has described another 
specimen of Sternberg’s species, Noeggerathia foliosa: and fixed 
the genus thus: Mrondes petiolaie, pinnate ; pinnee obovato-cunet- 
Jormes vel obovate, lateribus petioli applicitis semi-amplexicaules, 
nervis numerosis teneribus, plerumque simplicibus ab ima basi adscen- 
dentibus percurse.* Géppert then describes two new species of 
this genus: WV. obliqua and N. Beinertiana. The figure of both 
r. Gdppert refers this genus. Brongniart, in his Zubleau des gen- 
res has described again this Noeggerathia foliosa and from the sim- 
ple pinnate form of the frond, the rigidity of the leaflets and the 
mode of nervation, he compares it to a palm or rather to the 
American Zamia. He has thus made a separate page the 
Noeggerathie, and places it between the Cicadee and the Converee. 
This Family contains only two Genera: Noeggerathia and Pychno- 
phyllum,t this last one replacing the Flabellaria of Sternberg or 
rather including only Flabellaria borassifolia Sternb. Mr. Geinitz 
in the Versteinerungen, &c., has apparently admitted Brongniart’s 
views. “He places the family of the Noeggerathie with the Dicotyle- 
donous plants having the same two Genera and refers to Noeg- 
gerathia a number of fossil fruits of the Genus Rhabdocarpos. Th 
variety of opinion and uncertainty of the characters of both the 
genera Noeggerathia and Cordaites, is perplexing indeed. Butl
