900 SYSTEMATIC PALEONTOLOGY 



very close to the plant from the greensand of Niederschoena in Saxony 

 (Cenomanian) named Fucoidcs dichotomies by Keich and renamed Hali- 

 serites reichii by Sternberg 1 from its fancied resemblance to a recent sea- 

 weed Haliseris polypodoides Agardh. Bronn 2 also figures this plant ; 

 Eossmassler and Cotta refer it to Chiropteris, and Schimper transfers it 

 to the genus Delesseria because of its supposed resemblance to another 

 recent seaweed, Delessaria ruscifolio Agardh. Finally Rothpletz,* recog- 

 nizing its dicotyledonous nature and unknown botanical affinity, has pro- 

 posed that it be called Pliyllites reichii. 



There is no doubt but that the Raritan and the German plants are con- 

 generic but different specifically. 



Another somewhat similar form is Ar/tlia finntta Velenovsky 4 from the 

 Perucer schichten (Cenomanian) of Bohemia, which is compared with 

 recent forms of Jatroplia, Vitex, Cussonia, etc. It is hardly an Aralia, 

 and is probably congeneric with Fontainca grandifolia Xewberry and 

 Pliyllites reichii (Sternberg) Rothpletz. 



A single broken specimen represents the first of these in the Maryland 

 region.
