DISCUSSION OF THE FLORA. 



SPECIES REPORTED FROM THE LOWER COAL MEASURES OF MISSOURI, 

 BUT XOT INCLUDED IK THE FOREGOIXG ARRAKGEMEKT. 



As was remarked in the introduction to this report, the descriptions and 

 discussions given herein reh^te onh' to species of which I have been able 

 to examine specimens from the Lower Coal Measures of Missouri. Fortu- 

 nately, nearly all the Paleozoic plant material from ^lissouri ever published 

 bv Professor Lesquereux was collected by Dr. J. H. Britts, of Clinton, 

 JVIissouri, to whose enthusiastic and continued researches paleobotany owes 

 a o-reat debt, and this material is now either in the private collection of 

 the latter or in the national collections. The latter include not only the 

 extensive consignments forwarded from time to time by Dr. Britts to the 

 United States Geological Survey and the United States National Museum, 

 but also the private collection of Professor Lesquereux, which passed into 

 the great collection of Mr. R. D. Lacoe, of Pittston, Penns.vlvania, through 

 whose generous patriotism and disinterested love of seieiace they were 

 transmitted as a part of the Lacoe collection to tlie L^nited States National 

 Museum. 



Two lists of the fossil })lants from the Coal Measures of Missouri have 

 been publi.shed. The first of these, by Professor Lesquereux, which appears 

 in the summaries at the end of the Coal Flora^ comprised an enumeration 

 of the species described or identified from Henry and Vernon counties up 

 t(i the date (1884) of the termination of the manuscript for the third volume. 

 I repeat in the following list the enumeration there given, the species 

 discussed or quoted as synonyms, etc., in the preceding pages being- 

 marked with an asterisk (*): 



* Alethopteris amhigua *A. Serlii 



*A. loncJiitica^ *Annularia longifoUa'
