230 FLORA OF LOWEE COAL MEASUEES OF MISSOUEI. 



Whatever tlie interpretation offered, the superficial characters of these 

 stems seem to be quite diff'erent from those of any of the existing L}'copo- 

 dineous genera. Consequently, in an earlier publication I proposed for 

 those trees with this type of embossed cox'tex the generic name Omplmh- 

 pldoios. The diagnosis of the genus, of which 0. cyclostigma is the type, is 

 postponed until the relations between the oval boss and the leaf cicatrix 

 are more clearly demonstrated. 



A specimen which I regard as representing a decorticated or Knorria 

 state of this type strongly resembles the Knorria of Bothrodendron, to 

 which genus ours is perhajis most closely allied. 



Loccdities. — The originals described by Lesquereux from Clinton, Henry 

 County, Missouri, are Nbs. 5501 and 5502 of the Lacoe collection, U. S. 

 Nat. Mus. Later accessions are from Deepwater, U. S. Nat. Mus., 60771; 

 and from Pitcher's coal mine, U. S. Nat Mus., 5636, 6024, 6030. The 

 Knorria fragment, of doubtful identity, is from Gilkerson's Ford.
