first, TZ. smith was transmitted to him without label, but 
it is supposed to have come from the Pottsville of Ala- 
bama. The other, 7. truncata was found in the Pottsville 
(‘‘sub-conglomerate’’) of Campbell’s Ledge, Pittston, 
Pennsylvania. Lesquereux questioned the reference of 
this species to Taeniopteris.. Both of these plants belong 
to Megalopteris a genus characteristic of the Pottsville. 
David White” has also described a species, Taeniop- 
teris 2 missouriensis, which is from the Lowest Allegheny 
or Upper Pottsville. There is a superficial resemblance 
to 7. jejunata but a close inspection shows that its affi- 
nities are with the Pottsville Alethopterids such as 4. 
mavima Andrews and A.macrophylla Newberry. In the 
later paper White questioned the genus and remarked 
that “‘perhaps it belongs more properly in A lethopteris.”” 
It is within the range of possibility that such Alethop- 
terids, Megalopterids and the early bipinnate ‘Taeniop- 
terids have much in common. White’s plant should be 
designated Alethopteris missouriensis. 
Alethopteris, so far as known possesses medullosan 
stems and is thus pteridospermic. The botanical relations 
of the Paleozoic Taeniopterids are most uncertain. The 
term “‘pteridophyll”” is usually applied to fern-like foliage 
of unknown attachment. The weight of evidence seems 
to indicate that they are marattiaceous ferns, although 
Sterzel"” observed Taeniopteris abnormis Gutbier from 
the Rotlegende of Chemnitz with a species of Medullosa. 
If this attachment can be substantiated, a portion of the 
‘Taeniopteris group is pteridospermic. Zeiller™ was in- 
clined to agree with Sterzel although he did not examine 
the material. Both I.C. White and Sellards are reputed
