strobilus, consisting of imbricate, adpressed, lanceolate and pedicellate scale-, which arc deeplj 

 cut in a flabellate manner into linear lobes, and bear two seeds, one on each side of the pedicel. 



The stems belonging to this genus are like those of Mantel I la, only Longer, and tin 

 bases of the petioles are shorter and imbricated. The fruit is known only from tin 

 scales and seeds found associated in the same bed, and correlated by M. Pome 1, as well as 

 built up by him into a cone. He considers the genus closely allied, from the rtruofcure 

 of its fruit, to Dion. .

The second species from the same beds described by M. Poniel (C. Buvignwri) is pro 

 bably, as he himself supposes, only a variety of C. Moreaui.
