Fig. 1 represents a knee, reduced to about one-fifth natural size, which 

 was detached from one of the stumps standing exposed on the beach at 

 Bodkin Point. 



Fig. 2 represents a " burl " or excrescence, reduced to about one-half 

 natural size, which was broken from one of the branches dug out of the 

 mass of debris at the base of the bluff at the same place. 



Occurrence. — Talbot Formation. Bodkin Point, Grace Point, and 

 Pond Neck. 



Collections. — Maryland Geological Survey.

Description. — These specimens are referred provisionally to this species, 

 for the reason that they also resemble very closely a number of figures 

 which have been identified as the closely allied species S. langsdorft 

 (Brgt.) Heer, so that it is a matter of considerable difficulty to decide 

 between them. Heer's figure of the latter (Fl. Tert. Helvet., vol. i, pi. 

 xxi, fig. 4) is practically indistinguishable from the former and both are 

 very similar to several forms of Taxodium, closely related to the living 

 T. distichum (Linne) L. C. Eich, which, however, are still either more 

 delicate or have leaves which are blunter than those from Maryland. A 

 specimen apparently identical is figured by Knowlton (18th Ann. Eept. 

 U. S. Geol. Survey, Pt. 3, pi. xcix, fig. 4) and referred provisionally to 

 S. angustifolia, but he says (p. 723) "It is likely that in a revision of 

 American fossil Sequoias this will have to be made a new species, unless 

 it can be correlated with some known form." 



Occurrence. — Sunderland Formation. Near the headwaters of Is- 

 land Creek, Calvert County.
