genus was founded, and such an identification would consequently be very 

 misleading. Until the existing tropical Monocotyledons are more abund- 

 antly represented in our larger herbaria, or more complete and decisive 

 Cretaceous material is discovered, the botanical affinity of these anoma- 

 lous forms must remain undetermined. The name chosen indicates super- 

 ficial resemblance and does not imply actual relationship with the modern 

 genus Doryanthes of the order Liliales. 



Little reliance can be placed upon a similarity of appearance in dealing 

 with fragmentary remains of this sort, and the foregoing are mentioned 

 merely as indicating the presence of undetermined Monocotyledons of 

 large size in the Cretaceous floras of the world.

Description. Leaf fragments up to 6 cm. in length, varying in width 

 from 1.5 mm. to 4 mm., averaging between 2 mm. and 3 mm., slightly 

 keeled, becoming thicker and narrower proximad; midrib moderately 

 prominent. Lateral veins, which are parallel with it, very fine and 

 scarcely discernible except in the larger specimens. 



In common with other fossil remains of grasses and sedges this species 

 has no botanical value, except as an indication of the presence of plants of 

 this type in the Cretaceous ; it has, however, like so many fossils of vague
