 refeiTed to other forms described in the preceding pages, thoiigh the names 

 have generally Ijeen omitted from the discussion for the reason that I have 

 not seen tlie specimens on v/hich the determinations were based. Such are 

 (1) the Lejndodendron Sternbergli, which, as seen in the collections identified 

 by Professor Lesquereux, was sometimes interpreted so broadly as to include 

 branches hardl}' distinguishable from L. lanceolatum, to which I am inclined 

 to believe the fragments from Missouri mny have belonged; (2) the Xejpi- 

 dostrobus Goldenhergii, which is no doubt the cone correlated in the fore-
